Rectifier Rolling in Tweedle Dee Deluxe and Tweedle Dee Champ

[akuster777]

I'm still a bit of a beginning-intermediate builder, but I've been advancing thanks in no small way to the knowledge on this forum.

Anyway, lately I've been chasing tone in my four tweed amp builds:

• a mojotone 5e3 build
• a tweedle dee deluxe build using a PT from an old Magnavox turntable monoblock
• another tweedle dee deluxe build using a Mojotone PT and with a switch to enable a solid state rectifier
• a tweedle dee champ build in a deluxe chassis and cabinet

I built these one to three years ago, and I had settled into using NOS 5Y3 rectifiers without really experimenting or tinkering, but recently I found the tone of the deluxes to be too saggy for my taste. So, I swapped in a bunch of rectifiers that I had on hand and took measurements to try and match more closely the voltages in the Dumble specimen.

Attached is an excel file of the voltages I've found with various rectifiers. Noteworthy is that my dee build with the old Magnavox PT needs the GZ34 to get the voltages close to the specimen, whereas the Mojotone PT gets voltages closest using a NOS RCA 5Y3.

A QUESTION: Does anyone know the B+ voltages for the Dumble tweedle dee champ specimen? I can't seem to find them in my search through old posts here.

I'd appreciate more experienced thoughts and experiences with dee voltages....

Best wishes to all,
Andrew

The Champ B+ is the same as a stock Tweed Champ. There is really only a couple modifications to the stock circuit.

Thanks, Charlie Wilson!

Are there any other publicly-available voltage readings for other Dumble-modified deluxes aside from that specemin?
