As far as I can remember it was fairly simple – as per the third photo in the album (the one with the red tape). The 50ohm resistor is soldered directly to the centre pin of the GR-874 and the two diodes to the ground. Despite the warnings in the manual about disturbing this RF cavity, my peak detector seemed to test ok after the repair. I had no choice anyway as the 50 ohm resistor was broken in half. I was just careful to select the new resistor to measure as close as possible to the correct value.

Great! Thanks for that, pretty much exactly what I was looking for.
Do you remember what the other side of the cavity looked like with the connection to the input jack?
