Adcom gfa-5802
Hi
I have a gfa-5802 on which the power led is dead. Since I do not have the service manual, and the schematics I got my hands on, does specify what LED to use I wonder if anyone knows the ratings of this led? The schematics indicates a 2volt difference on each side of the led.

Probably a standard red LED, that's what they drop.

What is the size for the main supply capacitors on GFA 5802?
Four 22,000uF at 100VDC. These are large cans with screw terminals. Finding replacements
that fit mechanically may be difficult.

Yes I know the electrical values. I bought one recently and it already has a replacement in on the channel which hums. I was hoping for the physical (mechanical) values (diameter/height/distance between terminal screws).

If you can see the mfr part number on the replaced cap,
it may still be available for purchase.

Yes it's this part in the BOM on the service manual.
Out of stock. Will dissasemble the unit then report here with the size measurements.

As per this post ADCOM 22,000Uf 100V Back in Stock the size is 63.5mmx117.5mm can only and they can be replaced with these: E36D101LPN223TDB7M United Chemi-Con | Mouser Romania

Replacing custom made power supply capacitors can be difficult to source and expensive (4 of these will cost ~$120 with shipping). Need to factor that in to see if it is worth the repair vs possibly buying another unit.

Confirmed mechanical size and replaced with mouser part above. New ADCOM black caps 22000/120 are a tad bit shorter than the originals.
In my case one of the resistors for input ground 10R was burned up, was like 22k when measured. Replaced and everything is well now.
Also replaced the 4700/16v for Panasonic FC 5600/25v, the relay with 16A piece and the thermistor.
