Hey all,

Nice to see that after my 7 year absense the congeniality factor here is
unchanged g.

For years, I have been noticing in my RCA tt-4 a tube designated 5556. The
specs for same make me really want to have a go at this one, but I have
never seen one for sale anywhere, and am beginning to wonder if it was ever
even produced.

Anyone seen one of these critters?
