Coronado Oscillator problem
#4

Thanks to the both of you for the replies.

I did perform an IF alignment first and it didn’t take much to peak the transformers.

I probably checked R20 and will look at my records to be sure.

The dial was calibrated using the alignment instructions which called for fully opening the tuning cap. When the cap is closed, the dial is at it's lowest  reading.

The tuning cap for sure looks original. I’ll look at the oscillator coil to be sure but I don’t recall it looking like a replacement during my initial inspection.

Oscillator does run but my really good multi band radio is not working right now so I’m stuck with one that has a crummy dial.

I’ll post the further results this evening or tomorrow morning.

Sometimes I wonder whether the world is being run by smart people who are putting us on or by imbeciles who really mean it.
