I am a Randy Fan and this is one of the most fascinating videos concerning his equipment I have ever seen. Thanks for sharing your knowledge. Respect Sir.
Absolutely loved the nearly cleans you got when you'd finished tweaking: reminded me of Lou Reed's New York album probably partly because of the chord progression you were playing but there's a very distinctive guitar sound on that album that this nailed for me.
I really love the content of you channel and appreciate your work and honesty. One question off topic, what do you think about tube amp attenuators, in specific the last generation of products with reactive load technology . They seems now widely used but from a tech point of view are they healthy devices to use with our tube amps? Thanks for everything !!
Are you rebiasing that preamp tube, Lyle? Grid leak changes? Cathode resistor changes? Maybe changing out the anode dropping resistor? A combination of all 3? Changing one of those 68Ks out? Heh heh heh! There are a lotta little tricks. It sure sounds wonderful now! Those cleans are to die for.
One of the things I find funny is the fact that Rhoads used 6ca7's not EL34's. Even if they are interchangable, there is a difference. Marshall knows this fact and yet still put EL34's in his signature amp lol. They took pics of the inside of Randy's amps and all of them had big bottle tubes. I've never even seen big bottle EL34's. Another issue is Randy used Altec Lansing 417-8H speakers...which are no longer made and haven't been since the 1990's. You'd think a modern company would make an equivalent to that speaker that would be as affordable as any Celestion speaker. I personally feel that when Rhoads died, the cosmos literally and actively buried his sound....specifically his live sound. He had a very specific Les Paul from an era that didn't last long, he had a pedalboard that was custom built and most if not all of the pedals were modded, he used speakers that we can't get anymore unless used. Intricate details of his gear was either buried or lost through time etc. It's just bizarre!
I like to put a cross line master in all my old amps, if there is an existing hole in a good spot.. Only for the time I have them. If they ever get sold, a couple minutes with an iron and they're gone. The suck in terms of useability (I am sure there are ways to address the touchiness), but for home use and not drawing noise complaints I think they are a useful way to bring volumes down. I have never felt compelled to use an attemuator.
I came up with a design of a cross line master volume with a dual ganged pot! 2x100k using one side with a capacitor to roll a bit of highs at lower volumes (form less harshness). The pot is cutted on the extremes so that on 10 its completly out of circuit. Sounds better than a Lar Mar master volume (which I think is bright at low volumes)
SM57 on a Veteran 30. No EQ, compression, reverb, or any other processing. And I didn't touch the tone controls throughout. Removed variables, but the amp could shape things more if needed. In a studio this would all be tweaked, which is what we are used to hearing.
@@PsionicAudio I can concur on this. Distorted Marshall type amps almost always end up with a lot of studio EQ added to them at around 7-8khz to add some bite to the sound. They always sound a bit muddy when recorded.
Gotta remember Randy goosed it with a MXR Distortion+ and a MXR EQ (with a good about of cuts and boosts), so if you’re referring to Randy’s tone, that’s HUGE part.
@@PsionicAudio I don't know about the Red Box, but it looks like it's more of a speaker sim which, going into a speaker, would make it sound bad. But the Suhr or UA, or any other attenuator shouldn't do any big EQ things like the Red Box.
@@PsionicAudio The Iron Man II is perhaps also one you might look at. The UA is quite nice for recording but for pure attenuation through a cab, the Tone King is quite nice indeed. YMMV. Cheers, Alan Tomlinson
since i'm new to your channel, old as dirt and dumb as a rock i would like to get your professional opinion about an amp i bought in 1987 and never used .... i never used it because it's very loud and it's called a marshall silver jubilee with 2-12 inch speakers .... it weighs as much as my old ampeg VT22 and that earned me 2 hernia operations .... is that jubilee the same as a JCM 800 ???? is there a mod to make it less bright ??? thank you
The silver jubilee is a unique circuit and one from '87 could be very valuable in today's market. Sell it, get a smaller lighter amp that suits your needs, and you'd probably have enough left over to get a new guitar too
@@PsionicAudio did that already sir.... the bands i play with now play very small places i fell in love with a fender super champ xd, 2 channels that work great for the stuff i do.... also have a marshall DSL made in UK that i can use for bigger gigs ....still have the echoplex i bought from danny gatton a million years ago ...thank you for your quick reply and advice
@@davidisenberg125 three thumbs up 👍👍👍! One for Danny Gatton, one for an Echoplex, and one for Danny Gatton's Echoplex! One of my few regrets musically is that I never got to see him play. I bought tickets to see him, but he canceled the tour, and a few months later he was gone. A tiny loss for myself, however, compared to the loss for his daughter and family.
@@goodun2974 it was'nt one of his personal ones, he kept those under lock and key because they were grey and had tubes... the one he sold me was a SS one and i think it was around 75 bucks... i loved it when he said i don't use distortion boxes and we would tell him the amps on 12 and it only goes to 10 so you kinda don't need a box.... what an amazing player and guy....
@@davidisenberg125 , I actually bought a Roland Space Echo a while ago (the pro version with balanced inputs) that I haven't had a chance to play with; it's missing the tape so I'll have to buy one or have somebody make one for me. They're supposed to be a somewhat more modern version of the Echoplex with additional features.. I am told that the dub reggae guys particularly like them. I brought some test equipment and other stuff with it but I don't think I paid any more for it than you did for yours.
I give out an awful amount of stuff. I keep some tricks for myself. Besides the clues are in the previous video's last schematic. Figure it out and you'll learn more.
In defense of Lyle and everyone else protecting their investment…Lyle owes us nothing and does not need to give away all his secrets. It’s fair to accept what he shows and teaches us is more than generous. If you follow closely and have a decent understanding of the subject, he gives so many tricks and tips away. Sharing is caring doesn’t work since there are many people waiting to steal someone’s idea and market as there own.
Well, I don't think that this is how we move forward and progress as a community. I don't think that Lyle (although I'm not confortable using his first name without knowing him personally) has anything to gain by hiding anything. I would even argue the contrary. Anyway, I don't mean to offend anybody. I'm sorry if I did and I apologize. I like to see other people actual physical implementations when possible but I understand Lyle is not required to share his. Moving on.
So why do you put tape over your unbelievably special "secret"? I'm not getting pissy. It's just that I have seen "techs" paint over components. So that you can't see the values. Because their circuit is SO AMAZING. And you know how theirs companies out there "cough, cough VHT" who will not give a Schematic because their circuit is oh SO special.

Beautiful. One amp to rule them all! I spent 35 years searching for this much versatility. Never found it.
I am a Randy Fan and this is one of the most fascinating videos concerning his equipment I have ever seen. Thanks for sharing your knowledge. Respect Sir.
I just scrolled through a year's worth of videos to find this and , blue tape hahah...
Man the amp sounds MEGA. The mids on this thing are like butter now!

You're so right.
That clean sounded so good !
The gain drive on the lower setting with the bright car sounded pretty good too !
So glad I found your channel. This stuff is all fascinating.
This one’s way over my head. But I think I followed some in general terms. You’re work is fascinating.
Great sounds!
the end result sounds pretty damn good . Nice work .
Very good video thank you for doing this amp I have been wanting to get to see inside one
This was fantastic stuff. Killer sounds and far more flexible than your standard Marshall
Jeez, that amp sounds good!!
I really love the content of you channel and appreciate your work and honesty. One question off topic, what do you think about tube amp attenuators, in specific the last generation of products with reactive load technology .

All comments help, thanks for the hard work.
Very versatlie!

I wonder the gain if plugged into the low input of channel one cascading into channel two. Possibly the 47K in series replacing the 1.2k

Good old Larry with his jokes!
@@BradsGuitarGarage Glad I could make somebody laugh. Keep on rockin', Vlad!
Cleans are key gain can be your enemy just enough gain to get the job done, like controlled from your volume control
Is it important to use a high quality humbucker guitar to get the proper tones during set up? Thanks for the answer.
I swear I saw the finish on the acoustic guitar peel off in the background...
why did Marshall add the additional 1.2k grid stoppers on V1A & B? the earlier RR revision didn't have them apparently
to get rid of any potential for parasitic microphonics! Ideally, you want the grid resistor residing on the valve, as the 1.2k's are!
Don't hear, I can't shout you!🤣🤣🤣
Lol!
Love the cleans! The distortion is a bit muddy for my ears.

I think the customer should be quite happy with that. I would be.
You should make a simple attenuator, or buy something like a Suhr Reactive Load to test all your loud amps at a reasonable volume.
I have a Redbox, just don't care for the sound. Looking at Suhr & UA.
@@PsionicAudio You might also look at the RedSeven Amp Central, for my money it's the best sounding reactive load (also has a resistive load).
@@PsionicAudio I don't know about the Red Box, but it looks like it's more of a speaker sim which, going into a speaker, would make it sound bad. But the Suhr or UA, or any other attenuator shouldn't do any big EQ things like the Red Box.
No, I use the Red Box with a dummy load.

Thank God for JMP 2203's. The RR /AFD / YJM all money grabs by Marshall Bletchley IMO.
THIS
sqqquukweeeerttt... oh good lord what will we do next help me help me
El from TAD clearly requires a higher level of load.
Nah. If you have a bias voltge of -36 in a 1959 and the tubes are @40% dissipation the tubes are weak. The JJs were bad.
@@PsionicAudio
Well, yes . I'm just listening. You know better)
Soo, by making the "tweaks", really, this amp is no longer to Randy Rhoads/Marshall-spec, but a better sounding (in your opinion) Marshall?!??
Small rant incoming. I will say I'm a bit bummed (but mostly surprised) by the whole blue tape shenanigans... Sharon is Karen, no?
I give out an awful amount of stuff. I keep some tricks for myself.

That .0047 bright cap is the key to that type of sound IMO. Amp sounds pretty good good job. ☺️
