Technics SA-5760 recap

[PaleAleKing]

Good morning,

After searching the forums, I did not see a recap / upgrade BOM or other list posted.

Yes, I can refer to the SM and get out the calipers and spec them myself, but my problem is time.

There are the kits on that auction place, but goodness, they are seriously marked up!

If a kind AKer has such a list and would be willing to post it, I would greatly appreciate it!

Cheers!

I've done two, don't have a list because I keep 90% of parts in stock, but IIRC R708 gets pretty dang hot, I might have put a 7W in there. Relay is LY2-0-DC24, and I'm pretty sure there's some transistors on the driver board that need to go, the dual input pair for sure and the predrivers I believe.
The main caps always seem to gut badly for some reason....

Thank you! This helps.

I think I already spotted R708, it looks like a real cooker.

I wonder what the derating is for the main caps? I've barely started working on it. Maybe they cut it too close, otherwise imagine how much bigger the chassis would have to be. It's already a monster!

Once I get this beast stabilized, I'll take some IR photos to identify other hot spot / trouble areas.

i’ve just acquired one of these receivers so any info you can share on the rebuild would be appreciated. thanks

i was looking for R708, the big black area on the pcb helped me find it!
