A friend of mine was impressed with how well my dad's old Pioneer SX-535 sounds after I fixed it, so he asked me to check out his Nikko 8085.
Here it is opened up. DeoxIT fixed all the sound issues. A couple channels didn't work and the left sounded all staticy, but after spraying all the pots and switches and turning // flipping them it sounds good. The sound is clear, even on AM and FM.
I did notice the tuning needle for FM doesn't hit the best sound in the middle. The best sound is a little to the left. Can that be adjusted?
The remaining problems are cosmetic. Here you can see most of the radio signal guide lights are dead. I hadn't seen these bulbs before -- I thought they were fuses at first. I'm not sure where to get these or what they're called. I pulled one out.
Bulb dimensions
Length: Approx 29mm or 1.1875"
Diameter: Approx 6mm or 0.25"
The bulb has 8V0.3A written on it.
There are also dead bulbs for the STEREO, FM, and PHONO lights.
This is the stereo light bulb. I've not seen this type either. A very gentle tug was all it took to tear the corroded guts out of it.
The caps all look really old, but it sounded fine, so maybe I don't need to touch them?
I was initially going to look at replacing and upgrading these bad boys, but again it all sounds good right now. DeoxIT did all the work for me!
The final cosmetic issue is all the knobs and switches have like little marks and some kind of brownish residue on them. Is there a good cleaning product I could try?
