Hello all,
I have discovered how much fun tubes can be, and am in the process of
planning one or more transmitters to go along with my 2-tube
regenerative receiver Ross, NS7F


Forgo the handbooks and look for QST magazines from the
40s thru the early 60s. Many larger libraries have the bound
editions... At worst, look for some used QST on CD editions
from that era.
