Thanks for the pointer. Just finished the osc test with another radio. Was able to track the signal, staring at the top (1500), going down to 1260; 1250 was faded in/out; then nothing detectable farther down the dial. Think my 89B code 123 is at least Run 7 with det-osc #36 and speaker K-21. Believe there was also some work in the past (before it adopted me) due to having a 5Y3W rectifyer vice an #80.
