Oh man! This first board was a snap with the desoldering station.
No going back now!

FWIW snip your leads first then solder.
Interesting! I'll do it, but for my own edification, what's the reason?
tensleep.... sorry not to side track away from the current topic but I currently have a 2230 that I will be restoring as soon as I can get all the parts together. I followed a cap list here on AK for the last 2 I restored and that list calls for much larger values on the Filter/Coupling caps, but I’d like to stick with replacements closer to the original values for capacitance on this unit. What value caps did you use? I’ve tried to find the proper diameter caps on Mouser with the original value with no luck. Would you happen to have the part numbers for the large caps that you used?
G.T.

These devices are on the foil side of the P500 board - are they ceramic caps, or something else?
Tom, are those film capacitors across the terminals of each big cap original or is that a design add-on? If it's an add-on, what is their function? Thanks!That is not the power supply filter, but one of the output coupling capacitors. The 2.2Ω resistor should be wired in parallel with a small coil.

Those are film 'bypass' capacitors. The idea is that they negate the effect of any inductance present in the big electrolytic capacitors.Tom, are those film capacitors across the terminals of each big cap original or is that a design add-on? If it's an add-on, what is their function? Thanks!
