Need help on opamp replacement

[ConradH]

Ah, sorry! I saw Sansui and thought that's what it was. Anyway, the schematic is for Sony so my comments still apply.

Next on the agenda would be cleaning the input selector contacts and replacing the speaker relays (causing left channel loss over long listening periods and sligtly weaker left volume)

You seem to be working backwards.. Address these issues and give it a good listening time before messing with the phono board.
Note @ConradH noted those transistors in the phono circuit may be something to address/ replace vrs a cap approach.

Yeah sorry about this, but it couldn't be helped as the relay parts are not available locally. I've yet to purchase them from Mouser, as I'm also currently making a shopping list (so I won't have to order again so soon for missing parts).

I'll get into the input selector contacts this weekend, I've only recently discovered it as I don't usually switch out of phono input. It just surfaced when I noticed the left channel gets distorted if the selector knob is turned towards the edge.

Thank you very much for your help @Binkman & @ConradH !!! I'll return for any updates
