I've had my R392 for 25 years or thereabouts. It works well, even on SSB.
Originally I took an old tube socket apart and used the contacts to
connect power and speaker. Afterwards I saw that Fair Radio had the
connectors for about $20 so I eventually got one.
I'm powering it with a surplus 24 volt voltage and current regulated
supply. It limits at 5 amps so the tube filaments come up gradually. I
built a speaker box for it that also holds the power supply and a 600 to
8 ohm matching transformer for the speaker.
If you need any, I have some spare 26A6's. I also have a non-working
392 for parts.
Feel free to contact me for more conversation.
