Default Iv got a 100w OPT That needs a circuit

Hello Guys,

I have a Massicore 100watt 4.5k output transformer (43%UL taps) that I need to put to good use.
There are many circuit diagrams on the web, mostly using kt88 tubes but the decision it tough....

I am basically looking for :
-high power
-low complexity

Can you guys recommend some of your favorites?


Thanks all

I had a similar transformer and used 4 off EL34 in the output stage.
You just need some front end amplification, tone control and phase splitter and you are there.
