Manny's Vocal/Instrument Amplifier

I messed with the amp for a while, but I don't do well when I don't have a schematic. This amp sat on my bench for quite some time pushed off to the side. I don't like having non-working stuff occupying space on my bench so after a while I tried messing with it again. While working on the amp, in the back of my mind I'm thinking, who really wants an old transtube pa anyway other than someone who's into Manny's nostalgia.

Around the same time I started looking at trying to pick up a Marshall head. I don't have a Marshall in the collection. Then I saw the prices and remembered why I don't have a Marshall in the collection. Even the Marshall kits are a grand. Then I'm like, hey, the Manny's amp runs on EL34s and it's the crappy ss preamp that I'm having issues with. The light when off in my head and the Marshall amp build began.

I decided on a JCM 800 Master Model 50w MK2 Lead 2204. There are lots of schematic, layout, and build information on this amp which is just what I needed.

I ordered a pre-made turret board from Mojotones. Then assembled the board myself. The rest of the parts came from regular suppliers. I reused the PT, OT, power tube sockets, bias pot and bridge rectifier from Manny's amp.

I had to work out some bugs upon initial startup. I replaced one wrong resistor, and installed a missed cap. Then I had to redo the wiring to the pots due to squeeling. Now it sounds great!
