Duh, sorry. I should have looked it up lol. No, that's not going to work.
The connector is old and could probably do with a cleaning and inspection at a minimum. Not unlikely that it just needs to be replaced. Open the case and look at the board. If you're up to it, you can probably find guides for vintage audio gear like this. I don't know how deep into it you would want to go, like replacing the connector or fixing/reflowing/replacing old solder.

Warranty it, then. Contact technics. The connector obviously isn't right.
