Yes sir that’s all correct - using the CW and X mode.? No key present.

Any other possible reason?

The radios history is unknown.

Be sure that the SIDEBAND switch is on "X-CW".? If you're tuning in CW mode, you either need the KEY jack to have nothing plugged in or close the key contacts.? Likewise, if you transmit on SSB and have a key in the KEY jack, you need to close the key contacts.

I went through the tune up procedure and everything looked good until I got to the last step and the plate current never goes above .1 on the plate meter.

I have set the bias with the PS per the manual.

I checked continuity on the relay (both TX/RX) - it was good on both tests and I see it engage on transmit.

The system receives quite well - especially after tune up.

Looking at the bottom it looks like all the electrolytic capacitors were replaced.? The large electrolytic multi section was replaced by three capacitors under the chassis.

All tubes test good.

At this point I am stumped - unable to get any power out of it.

One other odd thing - if you turn the TX gain up past about three ticks while receiving you can hear an oscillation tone.

I have lots of test gear and have restored several other tube transceivers, receivers and transmitters so this is not my first "radio" LOL.
