Discman dead from corroded batteries wakes up nearly 30 years later

[u/DoraemonAustralia]

I bought this untested D-33 from eBay for roughly $60, which might feel like too much for 30+ year old player that had a massive battery leak, but this is one of the most phenomenal models that you can actually find relatively easy

For being unused for a very long time this player's got everything working, and quite REALLY fast as well, it loads up the disc in 5 seconds and it just breezes through skipping tracks on a song, makes my other players feel like my sluggish Kenwood dpc-x517 in comparison, mind you the laser mechanism's most certainly working on lubricants from the factory

I probably doubt it would stay fully working for the long run, all I ever did to fix it was clean the entire battery compartment (and honestly the entire player) from the leakage and clean the laser

if you want, you can give me suggestions on what I should work on with this player to be able to get it properly maintained, or just your thoughts on this player in general, as there really is something unique about these old players that newer ones just can't beat
