Hello all, New guy here. I'm attempting my first build, and I'm seeking some advice. I'm no stranger to amplifier circuits and how they function, but this is my first scratch build of an amp. I chose to build a 2204 circuit in a short box using the Granger Amps replica of the ST1 iss. 202 PCB. Yes, I saw the many hand wired layouts. But for authenticity's sake, I liked the challenge of trying to build it the way Marshall built it first before delving into modifications, hand wiring, etc. Sourcing transformers during the covid crisis was a REAL challenge. So here's a rundown of what I've managed to assemble: Heyboer Drake-wind OT Classictone Choke Mojotone Low voltage JTM45 PT 300-0-300 Yes, I'm aware those PT secondary voltages are low for this circuit but its what I could get on short notice. Call it an experiment I guess. The problem I'm having is I haven't been able to locate a good layout for using this board in a scratch build. Yes, I know it is much like all the hand wired layouts in form, but if there were a visual reference I could use to assist in connections between the board, the tubes, caps and transformers, I'd feel more confident about what I'm doing. I can read and understand the schematic, however translating that schematic into a functional layout is not one of my strengths. If anyone has a cheat sheet for wiring up an original ST1 board, I'll owe you one. I spent the better part of Saturday populating the board by cross referencing the schematic with gut shots of old JMP 2204's and looking at hand wired layouts. The real ST1 board has component values and indicators as to what model they correspond to silkscreened on it. The reproduction does not. So it took a little longer than I had expected. Once that was done I installed the transformers and caps, wired the heaters and decided to stop until I could get around to making this post. So please, if you could just take a look at what assembled so far. Is there anything that sticks out as wired improperly? I'm 95% sure what I've done is correct, but you guys have the experience here. If I screwed something up, I'd much rather address it now. Ok, lets talk specific questions. 1. Grounding. The Metro amps 50w build guide has ground points that seem to be all over the amp. Bus wire on the pots, grounding lugs on individual cap can mounts, all that. I've read a bit about Star grounding everything to single point, and also the Larry Method, which seems to make a lot of sense. But again, being new, I felt I should inquire about personal experience you guys have with the pros and cons of various methods of grounding. What works best for a quiet amp that sounds great? 2. Presence pot value. The 2204 schematic has a 25k pot and a resistor in the NFB network, while other Marshall amps used a 5k pot. I've read this can leave an amount of DC on the pot, causing it to be scratchy when turned. I don't really turn my presence pot while I'm playing. So... in your opinion, which presence circuit sounds better? Thats all for now. I'm sure there will be more questions. Thank you for taking the time to read this. Advice is welcome and much appreciated.
