got the following transformers lying around and would appreciate suggestions on possible applications:
-100W plexi OT 1k7 primary, 8 and 16 ohms secondary
-80W twin OT 2k/4ohms [or 4k/8ohms or 8k/16ohms]
-40W universal OT 4k/2,4,8ohms [or 8k/4,8,16 ohms]
-20H, 320ohm ac30 choke
-8h plexi choke, 110ohms
-4h fenderish choke
- unidentified BIG PT. Secondaries: 900VAC w/center tap, 6.3V & 5V (came out of 50w amp w/el34s with ca 600VDC)
I'm considering the following three builds
- using the big PT with the twin OT into a 16ohms load for a 8k primary impedance with a pair of el34s/6550s with around 400-450v at the screens at 600v at the plates
- a 20+W build with the 40W OT running 6v6s/5881s/kt66s at 8k into 16ohms load
- a 100w vox ac100 or plexi hotrod with the plexi 100w OT
Any ideas or suggestions?

Re: Transformers lying around - ideas for amp builds
Roe, I am making a 50w Vox killer with a selectable second stage as either 12ax7 or Ef86 + cascade.
My test says I need to fiddle with the values before I cut the board up, but it is Big JuJu. Going to rock. Look up Selmer Zodiac. Great amps.
