Hi el nino.
Skip the 8080 preamp, it's not cleaner than the 5010 one.
Make 2 5010 preamps, simply use one clean and one overdriven.
That way you design only 1 preamp PCB.
Only change is that to make it easier getting cleans, you should use a 22k LOG or AUDIO type pot for the clean channel volume ... and of course you don't set it on 10 !!!!!
The power amp is fine.
You'll also need to design some switching, but a DPDT relay makes things easier.
One section switches preamp outputs, the other shorts the unused channel internal audio path to ground, to avoid parasitic coupling.
It's annoying to have a clean sound and hear a weak distorted signal in the background.

if you don't mine, would you draw a schematic sir? That's very helping a lot
thank's & regard

...and there you go, the voice of experience.

you absolutely right sir,

Here's my current design for the 500 watt bass amp I mentioned in my previous post. Like to get it all down in the computer before hacking things together.

that's awesome man!!!
I think i will consider p27  preamp but the pwr amp is nice design Thank's for sharing

@mr. Fahey & mr. Roly
this is the plan sir, marshall 5010 as dist. Channel & valvestate 8080 for clean channel to efect loop then the nice design of esp p27 power amp, powering with -+15v for preamp and -+35v from 25-0-25 3ampere is that good enough sir?
Btw thanks 4 the link sir, the problem is i'm fired from my job because my boss don't like her daughter have relationship with me & my bank acount is closed now, so i cant shop online for now & i just can to buy component from my local radioshack ;-)

hello mate, i'm back...
I'm planning to build marshall lead 30 or 5010 from 80's to go with Rod Elliot project 27 pwr amp... Question is
1.is that a good match for blues & rock playing?
2.how to add another switcheable clean or metal? preamp?
3.any sugestion for clean or metal preamp opamp based,because it's hard to get jfet in indonesia
any sugestion will be very helping me,
best regard  Nino

you mean this?
i don't know your problem, but any senior in this forum will answer you

i've got an idea of making eighteen from ROG to go with tba820 on 9volt as a practice amp, but i plan to add ROG big daddy dist. in front of it as a boost channel like this:
guitar => big daddy (bypass on/off)=> eighteen=> pwr amp
question is, could it work? Or any suggestion for better design?
i love the tone of eighteen & metal sound of big daddy, that's why i choose them
regard's  NINO

thank you sir, i found this layout from google...
Can i use it? Or its need some mod?
It's very kind if you check it, if you dont mind... Thank's again sir

hi guys, i'm planing to build an ESP Project 27 power amp, can i power it with DC -+25volt and 2 ampere trafo? How much watt power can i got from it? Thank's
