My recently acquired Sony TC-580 is not playing tapes with any amount of quality. It is overall very clippy and buzzy.
In order to fix this, I bought a vintage Sony HE-2 head demagnetizing tool to demag all 4 of the heads, and also cleaned all 4 with isopropyl alcohol on a q-tip. Lots of brown came off on the q-tips so I'm guessing they have become somewhat corroded from sitting in a non-temperature-controlled Florida garage for who knows how long. Especially the record/erase head from the looks of it.
I followed the HE-2 instructions and didn't touch the heads with the tool. I just depressed the button from about 2 feet away, came in for about 5 seconds and waved the tool across each head, the came back out and let go of the button. The deck was not powered on or even plugged in.
Will the sound quality return to normal with another few passes of the demag tool and maybe another cleaning? I cleaned them the first time until no brown came off.
I'm fairly sure the demag tool is working as well; it buzzes when I pass it close to the heads.
The playback heads are contained inside of a bit of shielding around each head, so it was somewhat difficult getting the demag tool in there without touching anything. I may not have gotten close enough?
Or do I need to completely refurbish these heads and maybe lap them to smooth again? Or maybe just replace them entirely if I can find replacements?
Any help with this would be great. Although I own another reel to reel, that other one has never worked, and never will work, and mostly just sits around to look pretty. I've never had to refurbish tape heads besides cleaning and running a demag cassette through on a cassette deck, either.
So consider me a newb.
I'm not slouch when it comes to vintage gear repairs though, but mostly stick to turntables and amplifiers.
Cheers
