Set of RCA Tube Handbooks
This is a complete set of RCA tube handbooks. They have a super amount of detail,
and were used by my Dad at one time to design his Ameteur radio receiver/transmitter
or transciver back in the days of tubes.
Curbside pickup is preferable. If requesting shipment a charge will be applied
for packing, and shipping. I will need to price through Canada Post.
