I recently got my hands on a pair of UTC LS-58 output transformer and plan to use them with PPP 6B4G's . The output inpeadance is 2500 Ohm CT or 1500 ohm CT what other output tube could be used with out using four of them , i know PPP 5881's or 6L6GC would work but is there someting that would work into 3K PP that won't go over 40 watts .

I'd love to try 2A3's with this these, but more like 10 watts. Enough?

6B4G's are 2A3's with 6 volt filaments , i have a pair of the LS-57 that i'm building push pull 6B4's for 10 watts


Going to build two mono amps with the LS-57's

Hey Mark- that LS-58 with the weight written in sharpie (sorry about that) looks familiar.
Good Luck with your amp project, I'm glad I was able to provide you with one of the LS-58's.
They are one beautiful looking output transformer aren't they?
Send me a list of other Transformers you are looking for so I can keep an eye out for ya.


Thanks
Kevin

Hi Kevin ,

Whats funny the other LS-58 came from another forum member in a trade . will send you a PM .
The packing job you did was superb .

How about the 6AS7G?

Will still need 4 per channel , but i do have 8 of them squieled away . i was thinking of using them to regulate the power supply .

No, since there are two triodes in each bulb, only two tubes would be needed per channel.

Has anyone listned to the $50 chinese 300B tubes

Haven't, but if they are recent from Shuguang, bet they are really good.
