i have motorola am receiver that has a pcb connecting all the wires to tubes and components.
alignment with signal gen says to connect hi lead to pin 7 of converter tube, but tube socket is soldered to pcb ,no terminal on pcb.
what is the practical way that this is done.
i don't think i can get an alligator clip to hold on the pcb.
thanks
john

Make your own test terminal, by soldering a short lead to the pin 7 PCB landing or socket pin, on the upper side of the board.

I agree with the test socket adapter except in the case of an oscillator or converter tube, in which case I would take Fifties approach.

Be very carefull applying heat to those early PCB boards. There is a tendency for the traces to fall off when heated. Personally I would use a test adaptor.
