The Heathkit HW-12A is a single "mono-bander" 80 meter CW/SSB transceiver with a 200 watts P.E.P. The "final" power amplifier is based on a pair of 6GE5 tubes.
This transceiver was first introduced in 1966 and was sold until 1974. The HP-23 power supply, which was rebuilt for the SB-101 can be used to put this radio into service.
The 6GE5 tube was created for genereal usage as a Beam Power Tube used in horizontal-deflection amplifiers in television receivers of the era.

I followed the calibration and alignment procedure outlined in the manual and found the needed adjustments to be clear and straightforward. The is no pesky, final neutralization in this rig and alignment is vastly simplified because the rig only has one band to complete.
