Pentagrid, thanks for the reply.
I did the tests as you described and I could not get any signal on the AM radio tuned to 1mHz positioned near the mixer chip.
But I did get a signal at 84mHz when the mHz knob was set at the 29 mHz position.
Test gear, I do have an oscope, a vintage HeathKit signal generator (restored and works well), a cheap signal tracer, and Multi-meters.
Also another issue I should mention with this radio is that the 1Mhz tuning dial does not move properly. Rotating the large tuning knob to the left the drum display stops at the 200 mark.
When rotating to the right it goes past the 1000 mark to just beyond the small triangle. In observing the related tuning capacitor I do notice the capacitor plates do not fully open nor fully mesh at the ends of travel.
Also i feel a slight resistance in the knob when approaching both ends of travel. I read in another post that lubrication may be the problem but that did not seems to help unless the lube was not applied in the right place.
Do you feel this issue should be addressed prior to the lock light issue??
Brian
