Don't socket them as they will fail due to the heat from the power supply. They need to be soldered in only.

> hey folks, got a question: i was looking at my PSU on my cs80 yesterday, and realized there's 2 4558 opamps. i have had these fail in 2 other yamaha synths, so i was thinking of replacing and socketing them, in the interest of preventative maintenance.
>
> while i have the PSU out, is there anything else in it i should consider replacing? i recapped the PSU when i got it, so those are not of concern.
>
> thanks much. i know it might sound fussy, but its really my main synth now, so id like to keep it as healthy as possible.
