I'm progressing on my workshop move and will shortly do some radios and modulators based on the ECH81
At 12V, 24V, 90V and 200V HT
See

Feel free to add thoughts and stuff for me to try.
There are huge quantities of the NOS Russian version.
At 12V, 24V, 90V and 200V HT
- AM for Audio and 405 Video
- Old style TRF with headphones, the Hexode as SG and triode as detector. Second ECH81 as audio amp.
- Can one work as push pull output (150mA to 200mW), with Hexode "triodised"?
- What else? Theramin music maker?
