I'm a musician myself but I'm always super intrigued and fascinated by... Well... This. Like are you a musician, an electrician or a 1980's nuclear powerplant operator?
ooohf tough one!!!
Why not all three?!?!
@@Xalnop Fair enough lmao
electronic musician
artist
I was already thinking how awesome this video was then you brought out that 1930s radio from an aircraft and omfg that made for some great sounds! Thanks for the great video and inspiration!
When McGuyver meets The Prodigy.
Bob England he duck-tape some dirt and plants and they all transported to Mars?
shot the first chunk of this vid last. notice the grim burn i got right next to my eye from where i tried hot gluing something upside down...... sheesh that was a close call! if that went in my eye it would have been long john samver
Safety somewhere! Preferably towards the front!
Gotta keep all yer fingies and lookies working to keep making cool sounds my guy.
Hot gluing upside down..
How do u get in that situation?😂
Are the solder fumes are starting to kick in? Please, FOR THE LOVE OF ZARQUON, LOOK AFTER YOURSELF!
Love your work BTW.
PLEASE if you tour the usa please let me know
As I travel through your entire video list, I can feel myself ever so slowly getting closer to picking up a soldering iron and building something like this. I DON'T NEED ANY MORE HOBBIES!!! LOL
Your channel is great! I like that I feel I know more about how to create the music after watching you, not just hearing the sounds appear. Your tours of your rig leave me feeling better, not depressed. Like I'll never figure this out. Keep it up dude!
This is a great video, because of the fact that, I once wondered what v c a was short for. Question answered and in a very artistic style.
Just want to add that I love watching your youtube videos, I've subscribed to your channel, please keep them coming....cheers!
I'm not at all a musician and I can't even put together a 3-pin plug but am a fan of 70's electronic music, at a time when musicians literally had to spot weld their own equipment/instruments and I am utterly fascinated by your videos.
Amazing stuff, I was trying a Valve distorstion pedal on my synths these days and you appesr with this. AWESOME DUDE. In my short experience, for distorition to kick in on a synth wave (triangle, sine, any basically) you need to push the resonance high and set cutoff mid to low, and find the sweet spot of gnarl by raising slowly the freq cut (303 basic old stuff) I do this with a microbrute and lots of fuzz or distortion pedals and works wonderfully
An oscilloscope would've been nice to see the abuse the sine wave took..... Beat that sine wave up!!
Now you have one patron more! Looking forward to the building live streams! :)
dude your like my favorite person ever.
Do a wavetable module episode please.
I’m subscribing just so I can watch more lunatic presentations LOL. Informative AND entertaining! Such a rarity on UA-cam these days!
Totally awesome, especially with that old radio.
That radio addition is so cool!
I love this guy he's totally nuts off his rocker
Awesome video, keep it up with this series. Would be awesome to see also easy diy drum modules
More vacuum tube projects! This thing sounds so good
This is badass homie!!! More please Sir!!!
I kind of love this thing.
Cool as always
Sounds great!
Jesus man you are an animal, I love the sounds you create. Much love from Canada, please visit!
whoa that is so cool!
Круто Чувак! С тобой как в другую эпоху попадаешь!)))
I'll definitely have to try building one of these, I'm working on building a DIY Modular Synth from some leftover circuit boards from a defunct Yamaha CS15D Synth.
old-school-Sam-style : love it ! :-)
im struggling a lot to diy an usable vca... so this make me a little envy. :) just joking... sound is getting better and better there. yessir! i like that distortion a lot, a real ear candy if u ask me.
Bananas as usual! Keep it up! 👽👍!!!
That sounds awesome, that radio rules. You could get an FM transmitter and use it as a wireless patch cable :D I love the sound of valves. Funny (not so much for me, but anywhom) how I'm like fixing to build a 9v noob modular with (almost just) a square wave and a distortion (because I simply LOVE square waves and I had a distortion pedal that I used on a old organ that was in a flat I used to live in) :/ Lucky me I've been scrapping for parts to make some of the simplest oscilators you showed us, so maybe it'll not be for nothing aftersall. I think this VCA will be like the first 12v thing I'll do, for when I start realizing that 9v isn't respecting my artistic integrity or something, because I just love the sound of filters and valves. Cheers
That is some next level acid there.
I'd maybe put some sort of protective cage around the valve because I doubt they are cheap, but I really like the sounds its giving!
Just what I’m looking for
There’s a fine line between insanity and genius. But if you go there you’ll find LMNC running down it with his pants on his head. Always entertaining mate :)
Well, I'm blown away once again by your video. Nice work man. If you've not already named the valve distortion module, how about 'danger valve' lol...
Hi Sam, great video. I had a look at the schematic and what struck me is that the bypass switch shorts the output of U2. Looking at the specs of the TL071 it appears to have a short circuit protection system build in, so because of that you won't blow out the opamp. I have one suggestion though. You might change the bypass switch into a double on. When in bypass mode, you could disconnect the tube's heating. Especially if you modular has a lot of tubes and they are not in use all the time, this may conserve quite a bit of power. It would take away the nice glow of the tubes though.
LMAO awesome thought of a name! sv 2.0 crunchinator!
one step more to the horinzon ... generators of sounds (Triangle square triangle) with valves? flangers for voices? Great job!!!!!!!
Finally, a volume knob that goes to 11!
Love to see you make a bit crusher next or something chip tune related
Very niiiicee! 👌🏻 me like
awesome
ooooooohhhhhhhh!!! i'm makin this ~
instruction song is a hit ⚡
Your a fucking madman. Keep building thanks for sharing
Very nice project you share! Got me interested in doing some DIY myself :-)
Quick question about the potentiometers, can I use 0,4 watt ones instead of the 0.5 watt you've linked to? Would it affect the sound, performance or will it give problems?
Thanks!
what if it was called the danger valve?
nice!
i'm on it !
I’m loving the rabbit hole of gorilla synths I found with you. However, if I could make a suggestion, as both a seasoned guitarist and synth tweaker, you should consider placing the tubes inward. They break easy. It’d be true horror show if a misplaced knob tweak snagged against one and it busted. Also, best not to touch them if it can be avoided. As the snobs say, it decays lifespan. Keep it up dude, you rock.
How beautifully chaotic neuteral
Hey Sam love your videos, I get kick and an education out of them! I’m more of a guitar player currently but looking to expand into this realm, I only have a Volca Keys synth and the plug ins from Studio One, do you have any recommendations on what kind of module synths/gear is a good starting place like DIY kits, also any references for learning more about circuitry online? I’d appreciate any guidance you can offer, thanks Sam and keep doing what you do!!
Bit lat to the party but suggest an ultra bright red LED running off the CV maybe located in the centre of the valve socket so the valve pulses with the cv or whatever.
Nice
cool!
I'd love to jam my guitar through that!
1:03 this new Streets album has weird lyrics, but I'm learning stuff!
@6:25 What do you have going into that droning synth sound besides the Safety VCA? Also, do you have a make and model on that 40's (It's from WWII) style aircraft radio?
What marker do you use for the frontpanel, brilliant video's. I am going to give it a try to make a synth myself.
Can the 12AT7 be used in place of the 12AX7 using the same pins? also will this work fine with 9 volts or does it require 12?
Edit: do i need a 47nf cap or can i approximate to 40? I dont think i have a 47nf
Would there be a way of adapting this (or bypassing the valve) to make a 'normal' vca? Great vid as always!
Do you have any Tips, or even complete circuits for a regular VCA?
I would need a beginners tutorial on where to even start... love analog synths
can the squelch switch be replaced with a pot to "blend" the squelch in slowly?

Haha cool you made a song out if the instructions.... that was super dope! Love the beat! The boom baps hit hard with good texture. What did you use to make that beat?
I'm in the process of building a power supply for my new solderless breadboad I bought from my local Jaycar Electronics store recently, the power supply will be able to supply up to +/- 15V DC at up to 1.3A, both the + and - V are independently variable, once I know it is working like it is supposed to, I will be using it to test my Safety Valve Tube VCA module build and verify if it works, I will also be using the power supply and solderless breadboard to check that all the other modules I'm building for my big modular synth, work as they're supposed to, if not, I'll be able to mod the circuits to get them working right.
Dat distortions, tones and combinations. Hearing this by any mean, knowing shit 'bout who made it, I'd immediately tell it's LMNC. It's you having your `sound`, or handwriting, if you will, I can recognize it in every track of yours. Or when you're having shits and giggles with new module you invented like a day ago :D See you soon again in Amsterdam, mate! Woo! Thanks
Samyyyyyy🎹👽👽👽👽 huggs from Greece bro...have a sunny summer n keep 🏄 on wAVes of music! :+E @;•]
Screwdriver handle with a socket adapter and a long socket (so you don't scratch your panel with the pliers)
cool.. question..WHat do you use for sidechain effect?
1:04 looks like a chemical prozess:D
KORG NUTUBE 6P1 plat vacuum tube will work on 18V with a heater voltage of 3V.
Take me to your dealer... (S)he must have some prima medicine!
It's the new 874JB99-NVX70001 Valvetronic Manipulator Mechanism Device. Or the 874JB99-NVX70001 VMMD for short. (I know the full title can be a little long winded.)
that 12ax7 is SHOOOOT! RIP.
I'd like to see a tear down of that transcended 2000 from last video¿?
Could you use this as a regular distortion pedal?
is that a saftey pin? u wyld bro
If I come-up with some more mods for the Tube VCA, I'll definitely post them here for other builders to try.
Okay, so I managed to finish building my new solderless breadboard power supply last night, worked perfect first time I switched it on, no loud bangs, smoke, or other abnormal behaviour, anyway, I used it to test-out my Safety Valve Tube VCA build, but my build didn't work as I expected it to, so I'll need to do some debugging, one thing I did notice is that the 12AX7 tube I was using seemed like it wasn't getting enough heater voltage, in the schematic, the current limiting resistor for the Tube Heater, R5, is a 27 Ohm resistor, after doing some experimentation with other resistor values, I have found that R5 needs to be at least a 14 Ohm/5W resistor (15 Ohms/5W should work fine) in order to get about 12.6V on pins 4 and 5 of the 12AX7 Tube (it needs 12.6V at 150mA to heat the two cathodes to the correct operating temperature), if you're powering the module off a +/- 15V supply, one other mod to the Safety Valve Tube VCA that I could recommend doing is to put a 47nF (473, or .047) capacitor (it's an arbitrary value I chose that seems to work well enough, you could even increase it to let more bass through) in between pin 6 of the 12AX7 Tube and R7 (the 150k resistor going from pin 3 of U2 (TLO71) to ground, doing this gets the TLO71 IC (U2) biased properly so that pin 6 of the TLO71 IC (U2) is sitting at 0V like it should be, rather than +11V, since U2 seems to be being used as an amplifier to bring the output signal on pin 6 of the 12AX7 Tube, according to the schematic, we want it to amplify without distortion, so that we get distortion from the Tube rather than the IC, so, the TLO71 IC needs to be properly biased so that pin 6 sits at 0V, one other thing I noticed with my Tube VCA build is that when in Bypassed mode, I don't seem to get any output-signal, so I'm going to re-wire the bypass switch so that it works properly, one more thing I noticed with my build is that it will self-oscillate at some point when you turn-up the level control, I'm going to see what I can do to fix that, one more thing, the Overkill switch doesn't seem to work as expected, when switched on, there is no output signal so one more thing for me to fix, this is not necessarily a bad thing, this is what actually makes DIY electronics a fun hobby, tweaking things to get a circuit working better.
Do you use the same type of speakers for both playing/performing and also producing? Or do you have different types of speakers for different purposes? Or do you use headphones? Do a video on speakers plz!!
Very SID like sound😇. One of the sounds sounded accidently like something from commander keen...
Hi Sam! I love this project so much. I've been inspired by you and developed a Dual (quad) Tube VCA Module. I'd love to send you one to say thanks for encouraging me to make modules.
How can I get one to you?
Very crunchy anarchist??
Is there an easy-ish way of converting a stock GMSN diy safety valve kit into one of these bad boys?
love your vids but im new to all tbis could yoh do a video that explains why and whatvand how its making the sounds so i can understand better
just search for modular synths on youtube..
The way this adds "squelch" to sounds could take the fart box to another level. Farts are squelchy most of the time.. Or maybe that's just me
the drawing on this video and the one on the website page are different. the level pots connection are different, could you check and tell us which one is right?
The beat at 8:34 made my gf in the other room think there was a tornado watch
I built one of these bad boys on a bread board but i cant get it to work.
The valve I used is the ECC83S - note the S on the end...
on the websiteit says use - 12AX7 (also known as the ECC83) - anyone have an idea if the ECC83S is okay?
Should work fine try bridging the 27r resistor with a wire or remove it
That tube at 0:56 there does it work because it's definitly broken and i'll tell you how i can see that the top suposed to be shiny like a mirror your's is white. meens air got in and oxidized the coating. just a friendly heads up! :)
indeed!!! i clipped off the top of that tube to see what it would sound like as it rapidly oxidised, wasnt that funky sounding :(
Can someone please get a medic over here? I got infected by Influenza Synthtronica
Lets build some synths :P Thanks for your tutorials!
So it is basically a saturator, right?
chirp chirp!
on some randome radio channel a guy is talking about football and someone else at the same time is making music with it
That's the way Rick Sanchez would make a tutorial
Could the BC107 be swapped for a 2N3904 or BC547? I was doing some reaching and apparently 2N3904 is a good replacement?
yep
i tied 2n3904 first didnt work as well but still worked
FIY you might want to fix your stripboard layout. You have the +12v wire for the level pot connected to nothing, I can see on your schmatic the level pot is connected to +12v very nice project by the way it sounds grate! Me being a fan of distortion. Keep up the grate work.
