Heathkit SB-230 linear mods
Has anyone tried to use the conduction cooled 8560 tube (common in older
Motorola Micor,
etc VHF repeaters as a replacement for the conduction cooled Eimac 8873
tube?
Both have similar specs and I'd like to keep the conduction cooled feature
of my SB-230.
tnx,
Doug/WA1TUT
