[ARC5] Ebay Transactions

Id also be interested in hearing details about that portable tester.

Back when I was building quite a few amps for others and using the then 
freely available AM/FM BCB pulls, I built a tester that ran at up to 1000V. 
The HV, bias and filaments were Variac controlled and compared the static 
anode currents with the various published curves.
Results were tracking very well with those that worked at or close to full 
power at HF/6M since at the much higher HV used for transmitting the tubes 
were much more efficient.

Not portable but bench top and over the years I added several more sockets. 
A big 10" diameter round "muffin" fan on top and a smaller one below kept 
seals happy for the relatively short near full dissipation tests.

Noisy but effective and also doubled as a regettering jig.
