either will work.

The 50k resistors, how critical is that value, I have 47k and 56k will either of these work? I guess I could use 2x100k if needed. Bill N7OQ

Bill Here are a couple of old things i saved re getting the GBS-8200 workings with 8924 from the old Yahoo groups. There is also one on power supply repair plus some notes on power supply caps I

Hi group, I want to replace the CRT monitor in my 8924 and bought a GBS-8200 board. Well I saw a picture where they plugged it into the green (Y) rca jack on the 8200 board and this worked to a degree

Thank you everyone, I’ll order 105 degree caps and do a recap. So far everything else seems to be working. This is a great forum. Bill N7OQ

As others said, it is most likely the capacitors.? About 90% or more switching supply problems are the capacitors. I had an 8924c that acted similar.? I took a hot air gun from a SMD rework station

there is a write up in the files section ...or at least there used to be from the old hosting service. usually you are missing the green led on the rear of the unit which is the 15 volt standby

It is a very common issue with these power supplies. All the electro caps go faulty. Especially the little ones on the small boards. You need to change them all for 105 degree rated caps. The old 85
