Gregory Reverb 1500?

[Rhodesplyr]

Anyone ever seen a schematic for a Gregory Reverb 1500?

A customer wants me to repair his, and there's a voltage dropping resistor between two lugs of the power supply cap that's heat-damaged to the point where you can't read its value. It also has one transistor in the reverb circuit that no longer has any identifying marks on it.

Thanks!

Here's a hand-drawn circuit of the preamp/driver and reverb driver circuits of the Gregory Reverb 1500.

I've never seen an guitar amp input circuit quite like this--in terms of the number of components before the first gain stage.

And note that the reverb pot is the cathode resistor for the first 12AX7 section.
