Reconnecting reverb wiring to a Marshall 4210

Post by Geeze »

Like a fool when I cut the wires I didn't mark or record which of the reverb tranny's pins the return is wired to. The schematics are enigmatic.

Anyone know or have a gut shot of the reverb tranny on a 4210 or 2205?

There is not a red and Blue wire off of the reverb driver trans, as that is the primary / high voltage side.

The primary side will also test out at a far higher resistance then the secondary side.

Hi Steve,

Can you translate that into electronic dumb ass for me?

Are you taking about the reverb pan and questioning which end / cable is the return side?

Hi Steve,

I'm looking for which tap on the Reverb tranny the return wire is connected to. I took a pic when I bought it but can 't see where the wire goes.

Thanks for your help!

Here's a 2959 Lead with the same transformer. I'd guess the red lead goes to the PI node and the blue to the driver tube plate. The coax goes to the reverb tank input.

The first rule for taking anything apart that you are not intimately familiar with is making notes my friend!
Many times the 2 minutes spent doing such saves hours!

Taking notes and lots of high resolution photos prior to taking things apart OR modifying/changing anything,
