After auditioning dozens of speakers, and finally settling on a DIY speaker, for my near-cube room (4m x 4m x 3.5m H), I found a commercial speaker that conquered the room. It is the LSA1 from The LSA Group. It sounds very good, and is currently being driven by my vintage Harman Kardon 430.
However, I wanted a tube amplifier to ultimately drive this, and after selling my Anthem Amp 1, I'm left with flea powered amplifiers that definitely does not have the power.
So I wanted to embark on another project and to be more sensible, I will use a pair of 300B tubes.
The question is, should it be PSE or push pull? I have not heard any of the topology and does not know advantages of one from the other.
Can anybody enlighten me?
I also wanted to salvage the Lundahl LL1660S/10mA that I used in my last 300B to be used as either interstage or phase-splitter. The questions surrounding this would be, should I use it with single ended to push pull, or push pull to push pull (should I opt for push pull finals).
The other goal is to get as much power output as possible, and I've been playing with TubeCad that can do PSE, and I can only get 18W out of the 300B pair with around 200Vpp, with positive grid. Is there a way to do some 20W or more if I use push-pull?
Please bear with me as I'm a total newbie when it comes to push pull or PSE stuff.
