Hi all.
I have 4 NOS in box Brimar tubes labelled 6A3, but with monoplate structure. Happy to take reasonable offers. Also willing to trade for some nice output transformers, or who knows what else. Happy to offer a full-satisfaction money-back return policy if you are a diytube poster with a lot of posts. I can ship from 65616 if you can wait until mid-September. I'll be passing through Europe soon also if you happen to live in the old world, I could ship from the continent. Cheers.
