have re-capped numerous 892XA/B Supplies ...at this age they all just about need them before the PCB gets damaged.
Yes they are a pain to get out ....be careful on removing the switch "extender" ....the plastic is old and breaks easily. ?? The RF I/O has to come out first.
I usually just re-cap the low voltage caps ....the two high voltage ones never seem to need it though I have replaced? a lot proactively .
Make sure you get the cap on the low voltage input PCB ( mounted on the side )
You can usually lay the power supply on the top to do a final test before installing so it will have the correct load as well.
