What makes you think this? Kinda just sounds and looks like a multi position mid boost switch …Reeltarded wrote: ↑Sun Jul 30, 2023 4:25 pmA capacitive divider is the 6 pos switch. I am almost positive. It is on the signal side of the circuit with no DC to block at this point. I have provided a link with full description of splitting AC with caps.
2 poles, 6 positions. I count 7 caps. The largest brown cap (at left side) is bridged all positions on A (signal) side of switch.

Based on the co-ax wire used, and the discoloration of the heat shrink, I'm guessing this amp was done a long time ago, like maybe in the mid-late 1970s?
So this is three Dumble amps that Dennis Herring has sold off now.

Re: Dumble modified Fender Vibrolux Reverb
Whenever dumble started using the tan Draloric resistors within known amplifiers would be a good time stamp estimate

Re: Dumble modified Fender Vibrolux Reverb
Is anyone sure this is Dumble's work? IMHO this looks like a Rivera modified Fender, especially the 6 position mid switch. I have had a couple of these come across my bench back in the mid 70's when I was living in SoCal. It could have been how they recorded it, but the ones I played sounded much better than this example. The $45,000 price tag caused me to laugh a bit.
