I picked up this great high end tube record player this past week that works great. It is a Voice of Music unit and the amp runs a 5Y3GT with a single 12AX7 for a single pre and phase inverter into push pull 6V6s.
The specs on the
-Power Transformer
545vac @ .077a
5vac @ 2a
6.3vac @ 1.3a
-Output transformer
looks to be
6600 - 4ohm
I have a nice empty Fender Frontman 25 cab that will hold a 10inch speaker, maybe a 6G2 Princeton or any suggestions?
Thanks
Picked up some good transformers, any ideas for good builds?

Re: Picked up some good transformers, any ideas for good builds?
77mA @ 545ac limits the choices.
Older iron was usually conservatively spec'd.
Might squeeze an 18 watt variant - it was running 2x6V6.
Good Luck,

Re: Picked up some good transformers, any ideas for good builds?
Yes it was running 2-6V6 5y3 and 12AX7 do you think I can squeeze another tube in there like a 7025 to do a brown princeton? I know that original had like 600 @ 70ma I recall...that is pretty close. Worried about the heaters though too. Everyone seems to over shoot the original specs this is cutting it close on the other end.Bob S wrote:77mA @ 545ac limits the choices.

Re: Picked up some good transformers, any ideas for good builds?
I'm by no means an expert.
With new iron I tend to over spec. the PT.
Having said that, an extra 3mA or so on B+ is nothing.
300mA on the heater supply isn't much - I'd go for it.
But that's just me.

You can probably build a very nice low power amp with a pair of EL95's.
