Due to my age, I am selling my DIY GM70 amplifiers, I just cant move these around anymore and they don.t fit in my audio cabinet.
These weigh in at over 120lbs each.
Hand wired, matching high quality components
Monolith Magnetics 7K OPT
Monolith Magnetics IT transformer, gapped for 40ma
Large Chokes
Spare Edcor power transformers(I had them wound for more current)
Pick up in Florida only
Asking $3000
6E5P PreDriver
JJ2A3 Driver
GM70 output
Class A to 25W, A2 to about 50W.
Rod Coleman supply for GM70
Arduino for startup using 4 relays (90sec warmup)
Ground lift using diode bridge
Simpson amp meters for GM70
Multiple Fuse protection for OPT and amp

Looks well made. If it was mine, I'd be thinking bigger cabinet and leave it put. I'm sure you'll find a very happy buyer.
Build quality is really good, I’m a little ocd, all parts are hand matched. I already have low power diy amps on my Khorns.
The gm70 are overkill for those speakers and waf is low if I put them on top of cabinet.
Also making a smaller lower power version. Truth be told, I need a new project and don’t have the space for more amps.
This needs a permanent home since they are difficult to move.
I have several spare 6e5p tubes but no gm70 spares. Current gm70 set is new and has less than 20yrs on them
