looks like the AF amplifier is fine now, using abt 3 mA at 12V, Xtal oscillator uses abt 5 mA at 5V. Quite a bit lower power than the FT-817.
Having only one power supply in the shack for experimantation, I need to find a 78(L)05 in my pile of components, so I can test the XO and mixer. I wonder if the output of the XO is sufficient to drive the relatively low impedance (abt 2kohm) of the mixer. but guess it will.
No more soldersmoke for today. maybe a bit of reading for now.
