its an ECG123a. I am going to stop by the local surplus store, they have lots of old transistors.
Yea what threw me was the lack of other problems, just a little bit of horz postion (about 2" to the right), everything else worked perfect so like you I assumed the transistors were ok. was getting ready to replace the AFC diodes, checking them in circuit they looked ok. As long as I had the diode tester I did a quick sweep of the 4 transistors in circuit. When that one did not check I figured it was just a part shunting the BC, pulled it and tested again. I suppose if I had checked the voltages or waveform on that with the set running I would have seen it. anyway its all back together now. 121-447 GE-20 motorola HEP736 SK3124 ECG123a
