Can someone suggest a CW only, all tube tranceiver for me? Nothing
QRP, more like between 20 and 100 watts, no transmitter/receiver
separate boxes, and no SSB transmitting capability. I want glowing
tubes and CW, in one box (power supply, of course, on the side).

What you describe is what I've been seeking for 30+ years. There ain't none
made. So I built my own. Three of them, in fact. My latest one runs 100 watts
out on 80, 40, and 20, has RIT, cascaded 8 pole 500 Hz filters, beam deflection
mixer, no AGC, dial drive/capacitor from a BC-221, and lots more. The only
semiconductors are a pair of 1N34s in the SWR bridge.

807s in the final, 866As in the power supply....

The HW-16 comes close, but it is not a *true* transceiver - it's a transmitter
and receiver in one box with a common power supply. You have to re-zero the
external VFO every time you QSY.

Suppose you started with a Heathkit SB-101 (the 102 had a solid
state LMO), and removed the mike amp tube. It would be a CW only
tube transceiver, 2 6146's give you 100 Watts out.

You could cascade two Heathkit 400 Hz filters, using the space for
the SSB filter and just jumpering around the switch.

Relatively compact. 1 kHz readout, great stability. No RIT though.

You can probably buy a fixer for about $150.
