What would you build with this transformer set?

martyh · 23rd October 2011, 05:00 PM

Peerless 16309 output 10K primary with Ul taps
Peerless 6048 PT 880V ct with 60v tap, 5v, 6.3V (from PP 807 amp)
I have a pretty good assortment of potted chokes to use also.
I was thinking along the lines of a 6CG7/ kt66 williamson (obviously) but that seems so boring.

Don't know much about peerless trannys but I do know they are good.

Are the output trannys push pull?

Is this your first build?

Having some specs on them will help us give you some sugestions.

Cheers Matt.

Thanks guys,

Matt, the outputs are pulls from a 25 watt Williamson amp. They are push pull 10K with UL taps to 16, 8 & 4 This will not be my first build, I have built a few amps and pre amps from scratch.

Tinitus, I would be worried about the high voltage required for the GM 70. I have built a few amps but 880V + full wave rectifier is probably out of my league.

I took an ambulance ride after getting nailed from hand-to-hand (across the chest) with 1087 volts (what the meter said before I took a ride). I imagine the only reason i am alive is because I wasn't connected to the supply long enough. I remember the horrible agony of the shock, then getting thrown back by my own muscle contractions. Then I remember getting up, taking a few steps, and then looking back to see if my body was still on the floor... I wasn't feeling too good, so I called 9-1-1 and took a ride to the hospital. They kept me under observation overnight and released me the next morning. I got VERY lucky, and I never forgot that lesson. I still work with such HV supplies, but I am rigorously careful at all times. I fully realize that I got a second chance, and may never get a third.

BTW, I'm not relaying that experience to try to scare people away from HV and tube amps. Quite the opposite - have the proper respect and use the proper precautions and you will be perfectly safe. HV is no different from driving, handling firearms, climbing a mountain, having casual sex, etc. As long as you are safe, careful, and responsible you won't get hurt

BTW, FWIW I would build either another 807 (or 6L6) amp, or maybe a class A EL-34 PP jobbie. But that's just me.
