2a3 Tube Question

I'm using the ceramic base Sophia mesh plates and very satisfied. Great sonics.

Well constructed, well packed, and quick delivery.

I have no affiliation with Sophia.

I'm surprised nobody has mentioned any of the old RCA or Sylvania's??? Are these relatively poor sounding compared to the tubes mentioned above? thanx

Buying old power tubes is a crap shoot. Given the expense involved, most folks are a bit apprehensive investing in $500+/pair without a warranty.

The tubes might very well be NOS NIB but in many cases the seller has no idea how and where the tubes were stored which is critical.

All of course IMO.

Audiofeil, I hear ya but, how do they sound?

;^)

Sorry can't help you. All the 2A3 amps I've heard have used contemporary tubes i.e. KR, Sophia, et. al.
