After 3 years I've re-started my 2480 and I have no playback. I can see the tracks going by but not on the Master or Track meters. All settings look correct and I'm baffled. Any suggestions?

Try reloading the song. Sometimes this will work, although often your experience is indicative of failing capacitors on the main board.

Replacing them is not a horrible job and the board need not be removed. If you are comfortable with the solder iron it takes a couple hours. Each component on the board has an identifying number; I have a list of those numbers to replace. Recapping will also likely cure any crackling you hear in playback.

Usually, replacing the 100mfd 6v caps(48 IIRC) will do the job. I used 100mfd 16v radial lead caps for the repair.

DK, What is the number of that board? I bought another unit several years ago for parts. I might be able to swap it out. I'm comfortable with soldering vintage electronics but these things are the micro stuff and I'm not comfortable with those. I did a Marantz 2325 in 2017 and it came out fine although it's back on the bench right now. I also did the input resistor 'fix' on the 2480 twenty years ago when it was new. The only board on the second spare unit that was ruined was the inputs, I think someone dumped a drink into it. I'd gladly & gratefully take any info you're willing to share. Thanks!
