Just a quick thanks for the info. No time at the moment to have a good look, but will later on. The schematics will come in handy for sure. I know I have been getting the legs of the transistors mixed up. The photo posted might be off an FT7B as I only have two RF finals.

I coloured the supply lines to make it easier to follow.

The link will expire on the 31 May 2019, but if anybody else wants it after then, pm me and I will email it to you (approx 7.5Mb file).
The permanent 12v will be the collector and the 0.7v line (if opposite the 12v one) will be the base. Other two are emitter. |
Terry, thanks for the info, at least I can identify the lines now. Are those voltages correct though?? I want to ensure that the power hasnt just been turned all the way down before I start pulling things apart, but not sure what controls the RF out.
