[Boatanchors] WTB: 572B Tubes for Heathkit SB-200

[Radio AI2Q]

Howie, a few years back I replaced my Cetron 572B tubes with Cetrons from RF 
Parts. They proved gaseous and I sent them back to the vendor. Apparently 
their NOS old tubes suffered leakage. I then bought some Svetlana 572B tubes 
(Russian) and although they have a tad less plate dissipation, they work 
really well with great output.
