Hey all,
I want to thank again everyone that helped me proof the Sunn Model T layout a few months ago, I plan on starting that build in the very near future. In the mean time, I wanted to draw up a layout for a Marshall JCM800. I know that there are plenty of layouts available already for these, but I wanted to draw a new one up to help me practice reading schematics a little more.
here is the layout:

here are the schematics I referenced:
OUTPUT/POWER SUPPLY
PREAMP
and because those were pretty hard to read, I also used this to get some values, disregarding the power supply and bias supply:

thanks in advance everyone!

found a couple better schematics to help cross reference with the layout I drew up.

these might be a little different then the ones I initially was making the layout off of though. I need to update the resistors on the line out on my layout I see.
If I could get someone to put an eye on this I will be very thankful.

thanks kacernator,
there are a lot of JCM800 layouts already on the internet. However, the main reason I wanted to do my own layout is to help me practice reading schematics.
I have been a "paint by numbers" amp/pedal builder for a few years now and want to step up my game a bit.
thanks
