[ARC5] The 6U8 -

[Geoff]

That is used in many radios as the audio amp for the pentode section and get 
run hard in some, otherwise its just a good general purpose tube.

I have a pair of HP-606A's and after the initial overhauls they have been 
fine and used almost weekly for boatanchor service. The tender tube in them 
is the 12B4A which often develops H-K leakage; I stashed several NIB away 
before the audiophools discovered them. Adding a bucking transformer for the 
complete service bench a few years ago has likely reduced having to repair 
test equipment before I can repair radios and earn my keep! The bench now 
runs at ~110-113VAC.
