Single Ended Triodes (SETs), the ultimate tube lovers dream.

2A3 Options

I've posted about my single ended triode amplifier in the past. It's got a Mullard EF37A driving a JJ 2A3-40, with a 6CA4 rectifier and a CLC power supply.

Output transformers are Sowter SP-02, and power transformer is a re purposed RCA Victor console stereo transformer.

I shuffled this amp into and out of my system over the years, because although it sounded good with some types of music I could never get good synergy with any speakers. It wasn't powerful enough for my Tannoys, and I never really thought it got the best from my La Scalas either.

I recently rebuilt some Sansui SP-3005 speakers into brand new cabinets, and decided just to try the SET amplifier. The synergy is unbelievable... finally I "get" what all the fuss is about.

Just for some fun, anyone have suggestions about another kind of 2A3 besides the JJs I could use? Seems like a pretty easy Christmas gift to buy myself, and I wouldn't mind having some spare tubes now that I know this amplifier will finally get some miles on it.
