Thanks Fraser, indeed great info on that thread, thanks a lot.
I had a look at my 2LO osc by following your document. I didn't remove the blue cable from the feeder before applying 11.3v (which was not a great idea).
Oscillator was almost right, 4MHz off, but very unstable. I adjusted it and then I noticed output power (which was around -10dBm before) was very low (-40dBm).
Reassembled the unit and now it's completely deaf. :-(
I had a look at the bias voltage to ERA-1 and ERA-5 and they're completely off - 3.8volt for ERA-1 (max should be 3.6) and 2.8 for ERA-5 (range is 4.5 to 5.3).
Looking at the actual bias resistors present on the circuit, ERA-1 has 68 Ohm and ERA-5 29 Ohm. That looks to be very low for Vcc=11.3v which I applied
Is the actual Vcc when powered on 11.3? Maybe on 3162 it's supposed to be lower?
It looks at least ERA-5 is toasted, but I think it was fine before my messing around. I hope I didn't break more things by applying power with the blue cable connected to the passthru
Thanks,
