- All tube preamp, killer tone! My diy project based on iconic 2203/2204 circuitry. Preamp section only, with additional MOSFET line output buffer!
Thank you for watching!

Very clean work! Ever thought of posting links to parts or files? Exactly what I'm looking to build!
sounds excellent
This is awesome!! I wish more rack gear was available that had a classic look: toggles, indicator lights etc ie more amp-like aesthetics.
Sounds excellent as well!!
Man tha is awesome !!.........nice job !
Amazing biba
Awesome!
Sounds killer
cool suond!
Yeah dude. it would be nice to build one of those.
Hey! This is awesome! I’m curious about the mosfet buffer and how you handled the power supply/what you used?
Really awesome!!! I'm waiting schematic!!!
Schematic is classic 2203 peamp, without any changes 😊 only added mosfet output buffer after eq
@@Recording_Dailyyou just used 2 tubes for it? Like no phase inverting part of the schem?
@@bonecaodoposto9454 cara, eu que ele usou apenas 2 válvulas. Tem o esquema do preamp do jcm800 na net e é apenas com 2 válvulas. Eu não entendo nada de eletrônica, mas estou querendo fazer um preamp.
@@MsCybernet eu estou fazendo um de plexi 1959 com 3 válvulas e phase inverter, ja estou com todas as peças e placa prontas só falta juntar tudo na lataria
Достойно звучит! Отлично звучит пред.
Looks & sounds great! I would have bought a kit if there had been one [ I know it's an old post ] Do you have a file for the faceplate?
Звук огонь, а что делает мосфет на выходе? У меня есть преамп по jcm 800 но по оригинальной схеме на 2 лампах и на нем нет ручки presence. Какие модификации нужно сделать чтобы так же было?
How/where in the layout did u add the presence control?
Nice ! I intend to make one too. What kind of power supply did you use ?
Very simple filter with few parallel 47uF caps and series 1kOhm resistors after bridge rectifier. For filament 7812 or lm317 I don't remember now
Nice! What voltages are you using for the mosfet buffer?
Hi! High voltage, same as cathode follower cascade✌️
That faceplate is awesome. How did you do that?
This is simple printing on 1mm aluminum, "gold" anodized faceplate. Easy to find in any city I believe
Where can I see your schematic and build list?
What poweramp you are using? Very sweet sounding and good looking build.
John govan , straight to line input, impulse 4x12 greenbacks
It's IR greenback + sm57 from Amplitube (without power amp emulation)
@@Recording_Daily thanks. This is awesome. Hope you can share the schematic+ mosfet buffer you've added.
Звучит отлично. Запас по гейна больше чем на стандартном 2204, но при этом баланс частот сохранен как по мне. Можете написать какие элементы были изменены по сравнению со стандартной схемой для того чтобы увеличить запас гейна?
Добавьте 100нФ во параллельно катодному резистору во стором каскаде. Можете поиграть с номиналами. Также 680нФ в третьем каскаде даст небольшой прирост усиления
@@Recording_Daily а 100нф параллельно 10к во втором каскаде не сильно порежет низы? Обычно вроде рекомендуют ставить 0.68-1мкф в параллель к 10к, чтобы с увеличением гейна выделить верх и середину. Но я не пробовал не знаю. Просто интересно не сильно ли срежет низы 0.1мкф?
Killer sound! Can you post link to schematic you used?
marcelduh666 it's ordinary jcm800 preamp schematic, with little mod and mosfet buffer. I'll try draw it and share
@@Recording_Daily that would be so great. Thanks
Sounds Great!! Can you share some info about the mosfet added after Eq or at least a simple schematic ? Thank you
Can send you email
what did you use in the unit in place of the power section . Was it a 12AU7 ?
No power section. Only output buffer after preamp eq
Sounds great. Did you build this?
Yes, some diy in free time
Yes 👍
Great idea !!!
Do It for sale !!!
Hei bro...is there hum sounds...
What with the les paul with the rosewood fingerboard?
LP Custom Lite 2013
Hey great job, did you buy this as a kit?
Could be, let me know if you decide ✌️
@@Recording_DailyDid you make this yourself? It looks awesome, as if Marshall themselves made it.
What's the song at 2:00? I'm pretty sure i've heard Johan Segeborn playing it a couple of times.
I don't know, but you're right 😉 Johan likes to play that🤭

It seems Last Child, by Aerosmith
Hi!! Can i buy one?
Yo duuuuuuude, where can I get one of these? Save Us!!!!
How much would it cost me to have you build this and send it to me?

layout¿ Schematics? I want to do one for me WOW!
Just follow classic 2203 scheme. After eq add any mosfet buffer for correct line output level. Good luck 👍
@@Recording_Daily Nice! What voltages are you using for the mosfet buffer?
Normalno )
Koneshno
Hello friend do you produce to sell this rack. Thanks.
Could be if you decide
Great....please schematic?
Markim Mustaine I'll draw and share soon
@@Recording_Daily show my friend..i look forward ro it!!! Thanks
Can I just pay you to make me one and ship it to New York? Check out my UA-cam channel where I review guitars, amps and pedals when you get the chance. If you can make another one, please let me know! Thank you so much!!
