Zesto Andros PS-1 Tubes


I'm curious to know if anyone has tried NOS tubes and if so what were your results?

Thanks.

I received my Zesto Andros PS1 last Friday. A few days ago I put 4 new production Genalex Gold Lion 12AX7 tubes in the PS1. I think it was a nice improvement. I heard improvements in bass extension, soundstage depth and imaging. I was going to try some NOS tubes but the improvements provided by the Genalex tubes has me very satisfied. So far, I'm greatly impressed by the Zesto.
I didn't notice any additional gain with the Gold Lions versus the stock JJ ECC83s.
