Re: Where to find OA2 tubes for Frist Sound Amp?

OA2's are a very common 150v gas regulator tube, should be very easy to source thru any tube vendor. $4-5 tops. They last a long time, they are not all that different from a neon bulb.

National is a rebrander, so the tubes were made by someone else. Any brand should do fine.

I really doubt the sonics would be at all affected by the 0A2 as long as they are regulating correctly.

Then again, I'm sure someone will believe otherwise...
