Hello everybody,
I have finished with the restoration of the 86. I would like to mention a few points:
1.- Capacitor block: I have been very careful when removing the housing. You have to raise it a little. With a thin knife, the cables are cut between the block and the plate where the cables are welded underneath. In this way we avoid desoldering the cables and avoid damaging the board. I have put them NON-ELECTROLYTIC.
2.- The inter-stage transformer between valve 27 and valve 26, the primary was cut off. I have totally disconnected it. I have made the coupling to resistors, following the instructions in Ron's writing. Fantastic !!!!.
3.- The primary output transformer (the one below the speaker) cut off. I have replaced it with a 125A following Terry's instructions.
4.- I have carried out the calibration of the neutrodyne capacitors by means of a special coupling. One of the legs of the filament was not connected.
For the rest of the restoration ..... easy. No problem.
The radio sounds great.
