It ought to tune right up on the WARC bands, using adjacent band switch
position. First, you need to find out if the plate choke resonance is parked
too near any of the WARC bands. I have no idea what choke is used in that
amp. A little grid-dipping will tell you what you need to know.
BTW, I have picked up 8122's on E-Bay several times; NIB, for an average
of $50 per pair.
