New AB763 build, need transformer advise
« on: July 31, 2016, 09:43:38 pm »
Hi,

AB763 Deluxe Reverb 2 channel with mids and a post phase inverter master volume and GZ34 rectifier

I finally got around to starting this project. I have all the parts on hand except the two transformers and a turret board. I will order a Hoffman board.

I am considering ordering all the transformers from Hoffman. I was unable to figure out the MFG for the Hoffman PT 041316 and OT 041318. Price is not too much of an issue...well Mercury Magnetics is a bit too much for my budget!!..lol

Any thoughts on transformers?

Thanks,

Billy

BTW...I built the chassis myself from 1/8" aluminum...a real mind bending afternoon of G Code writing for my little CNC mill...lol

Between fishing, flying, and fooling around with guitar amps, somehow 70 years got behind me. Shorter of breath and one day closer to death as the song goes.

Send Doug a pm. Both of those should be fine. I'd rather have an OT with 4, 8, 16Ω speaker taps. Don't forget choke and reverb transformer.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
