Wiring on the Mains Transformer might be a little whacky but it’s completely different than the ones in the Metropolous Kits. this is a Metro Chassis. Dax

I have all dimensions written down

Just wanted to share my progress building a ‘78 Style 2203. I’ve always loved the 4 input look with rocker switches. doing that just for looks. My first complete build, most parts are from Valvestorm With the Trannys from Mojo, and they are monsters!!! when I’m done, I’m taking a trip to my...

I’m building a 2203 from the ground up. No kit. Gonna build slowly. But I need a couple items. I can’t believe how difficult it is now to Find Transformers!!! Was hoping for Heyboer OT and PT. Any advice? Anyone selling? Looked at new MM, Jesus $340 each!! Also, I need a back panel for a Metro...

I think you are correct!!! But I don’t see the 500pf cap.

Can you be a bit more specific? B+ Rail? Which ones are these?

And I had to move the NFB to the middle. The board was a project.

I’m going to build a 100 watt MV from the Ground up. My good buddy David Hopkins is gonna help me mod it into a fire breathing monster!!! Just started on the board. I’m no expert. And it’s not finished. Any advice or critique would be much appreciated. For example: I’m using 2W metal film...

Hello to all. I have ‘76 2203 with a board built and installed by George Metropolous himself!! The man!! It seems to have a resistor on the board that is not on any Board layouts. Anyone have any idea? Thanks Marked with Arrow

Mine sounds killer with no jumpers! Straight in to Treble channel. It does have the Hot Mod V2. Really really great. I don’t even know why I’m messing with it. It’s in a 100 watt big box.

Well I listened. I raised the board properly and replaced the .0033 with a .022 Sozo. And…. I don’t dig it. It got a little more thick, but also became a little more loose, flubby. I guess Marshall kinda knows what they are doing. I think I’m going back to .0033. I like tight!! I mean other...

Looking for a damaged, beat up, flogged JMP 2204 or 2203 to rebuild, I’ve got the tweaking/modding bug. Post here, message me, however it works best, just seeing what’s out there, thanks.

Why does my Studio vintage use a .0033?? Isn’t that trebly as all hell? SV20H

May try this once I ring out the Component starts and destinations. Non destructive, not too invasive and removable

Boy, if I just had a Schematic, I’d connect my .022 to each leg destination. Leave the .0033 in there. .025 is no big deal. I shined a light underneath, just can’t see where each leg of the .0033 goes. Somebody out there maybe know?? I’d be fired up to figure that out.

Well I figured it out and it’s kinda strange. The V1 .0022 Coupling Cap I’m looking for is a .0033!!! I always put a .022 in my builds here (Albeit I’ve only done 3) that’s why I’m here. I’m a Marshall nut, but not a master at Amplifier Circuits. This thing is mounted balls to the wall flush to...

I’m looking for the V2 cathode .68 and also the .0022 in this board. Anyone have the locations or a darn schematic?? Thanks I need a pro voltmeter I think. Dax

I’m really dying for a Superlead or 4 holer of some sort. But this just came up near me! 1983 2204 in almost mint condition!!! Opinions on 2204 vs 1987 or 1959. Thanks

Why don’t I see The Diode/Rectifier Section?

I’m really thinking about pulling the trigger on this Jewel!!! Very clean! Any experience with these? But it looks like some Caps aren’t there in the V1 section far side of the board, and some odd Midrange Pot components. Need some expert advice, it’s Canadian, 8 or 4 ohms only. Maybe kinda rare...
