Recently picked up a Sansui AU-505 integrated amp. In overall pretty decent condition, except for one issue: there is a very strange static sound, only in the right speaker, and only when in phono stage.

Aux works well theough my Wiim mini player.

I know it’s not my speakers (Celestion ditton 33) as they were working fine before, and I know it’s not my turntable or grounding wire (technics sl1210).

Any other similar experiences? Any advice would be greatly appreciated. I like the amp and would like to keep it.
