[Hallicrafters] SX-32 audio amp question.

[Karel J]

Hi, writing this on my phone from the ladies clothing store. Please forgive
crappy formatting.

I moved fairly recently and have been working to get my hamshack up and
running.

My sx-32 needed some minor repairs and alignment. No problem, but I noticed
one of the 6V6 tubes was not lit.

The other was quite hot, and audio sounded OK. I slapped in a replacement,
and the radio is again happy.

Since these are two 6V6 in push-pull, do I need to worry about matched
tubes? They were the same brand, which leads me to think they may have been
a matched pair.

Getting on fleabay shows me a few options for tubes. Normally, I buy NOS or
good tested tubes from hamfests or a place in Vancouver. Anyway, I am
seeing these *new* tung-sol branded tubes.

Back from a few years ago, you could still get Svetlana 12ax7s (the winged
c logo, I think) and they were great quality.

So, should I bother worrying about matched tubes? If so, new or verified
used? Or NOS?

Thanks everyone.
