how good is the sun audio sv2a3

Excellent amplifiers.

Harvey Rosenberg(aka Dr. Gizmo) had been saying great things about Sun Audio SET amps for years, before he died.

I'm just getting around to building mine. I noticed from looking at the schematic that it appears that this amp runs the output tubes pretty hard. Anyone have any experience with how long NOS 2A3s last in this puppy? I am also planning to experiment with a parallel feed output topology. Have my order in with Kevin for a pair of Lundahl plate chokes gapped for 60ma. Having a problem trying to figure out where the Jensen parafeed caps will go. These suckers are BIG!

sun audio sv2a3 updated report. i purchased the grande 6 and the eh 2a3 tubes after reading sam tellig's review. waited patiently for the tubes and speaker for 4 weeks break-in period. it is hard to put in words the pleasure i derived from listening to this combo, not to mention that these set up did not cost me as much as my previous systems. is this the end for me? maybe, but we all say that. upgraditis healed. thanks you sam.

Just want to update that after trying so many pairs of amp, I really like Sun Audio 2a3, with NOS RCA tubes. They are VERY good.

Which speaker cable do you hook with your SV2A3? I just ordered one and waiting for it......!
