Western Electric 422A tube.

Pretty rare these days.

Dated 1954.

Well balanced.

Old style grey plate.

Heathkit TT-1A tested!

Both plates test at 2450!

Great substitute for 5u4 Rectifier.

This tube should sound great!

See photos for values. The plates are almost spot on exact matching.

Please ask any questions if need be, e.g. additional testing etc.

Tube will come well packaged and fully insured!

Cheers!

Of note: I may just have one of the rarest Western electric vacuum tubes made with an engraved base..hmmm ;)

Please inquire.
