I've not been into R/C stuff, but I am into 'submini' tubes.
I recently built a 5-tube regenerative receiver for the 49 meter band using
5678's for the 2 stage tuned RF amp, detector, and first audio amp. A 5676
serves as the final audio driver.
Can you send me a schematic you used? I must have 20 of those, as well
as 1AD4 and 5672s. I was forturnate that someone gave me a bunch of them
and I've found them fun to play with. I've done a single tube regen (160m)
with it and stuffed in a small tin. I run it on an AA cell and three
9v batteries.
