I have an old Heath SG-6 signal generator. It uses two triodes.
I'd like to convert it to solid state. The switched coils, varible cap
and dial mechanism are very nice. Any suggestions on what kind of
oscillator circuit I should use? I imagine the difficult part will
be coming up with a feedback circuit that will cover the 160 kHz to 50 Mhz.
Any ideas? Has anyone seen any articles on this kind of conversion?
By going solid state and adding a few buffer stages I'm hoping I could make
this thing a lot more stable. 73 Bill M0HBR CU2JL N2CQR

You should be able to replace the triodes with FETs, this was done
occasionally when FETs first became available. You'll probably need to
fiddle with some of the component values. Don't forget to reduce the HT
voltage. 8-)
