Pioneer SPEC-2 recap and restoration thread!

I think I may have modded the case. Refresh my memory where the ARS-028 (LY2-DC48) relay is in the Spec2. I still have it I will look.

Large relay mounted via screws to the meter amp assembly board. Thank you for checking.

It looks like I modded the old cover to fit the new relay

Hi all and thank you mattsd for the thread. I'm ordering parts and have a couple questions:

1) C1: 4.7uF 35v CSZA: 505-MKS2B044701K00KS 4.7uF 50v- This seems to obsolete, but Affinity For Artifacts on eBay has some. Should I get them there or is there a better source?
2) It looks like KSA1015YTA's are obsolete. Are KSA992FBU's the correct substitute for both the Meter and Amp boards?

The KSA1015 have a higher collector current ratting , could be important here.

Thank you, it looks like the same eBay seller has those also, so I'll get them and the film caps from him.

Is echo war's Spec 2 thread still available? I used to do my Spec 2 . There are some relays that should be replaced.

If you're talking about the reed relays, yes it is and I did them already. Thanks for checking. I started this thread when I got it- Spec 2 Idle Current and Meter Weirdness
