About a year ago I bought a somewhat haggard but complete and functional SX-980 at a yard sale. I've been busy with grad school so it has sat neglected until now!
I'm by no means an expert so advice and corrections are much appreciated, especially since this is the first Pioneer I have tackled. Being a hobbyist and not a pro, I find that slow, methodical, and well-researched work has led to good results in the past so that's what I plan to do.
My plan is to perform the following:
1. Thorough cleaning and de-ox (complete)
2. Replace broken bulb sockets and bulbs, repair broken acrylic lamp holder
3. Replace electrolytic and tantalum capacitors
4. Replace larger power supply board transistors due to heat issues
5. Upgrade/replace power supply board transistor heatsinks
6. Very carefully clean and re-grease output transistors
7. Replace any other suspect components as they are found
8. Repair and possibly re-stain damaged wooden case, polish faceplate
I am working up a capacitor/component list and will post it this week. As per Mark the Fixer's recommendations I am planning to use Nichicon UKL to replace the CEANL, CSSA, and CSZA caps and UPW for CEA.
I have a few questions before I begin:
1. Is it worth it to replace the caps on the tuner board? They seem to be in decent shape and the FM function works well. Just trying to do a cost/benefit analysis since it may need an alignment afterwards.
2. Are there any other "while it is apart" components I should replace? I am considering replacing the diodes and resistors that are in the discolored area on the power supply board but am not sure if it is strictly necessary. See attached picture for details.
