SA-9500 Recap

I am looking to recap my SA 9500. Is is necessary to replace the mylar and ceramic caps? Or are just the electrolytics the ones that need changing?
Thanks in advance to all the experts here.

just the electrolytics. but watch out for the low leakage/noise electrolytics. which will be about half of them in this unit.

no formal parts list as of yet, although I have done a few units....

and using the low noise caps makes an AUDIBLE difference.

this is a STARTING point, there are no replacement parts numbers nor any substitutions:
presence on the list does NOT imply replacement!!!

A few dumb cap questions

Thanks Mark, I will be putting together a list from mouser and digikey. I will post it when complete.

Now time for my first dumb question--When looking through the mouser parts list or even the list from the pioneer service manual, How do I identify the Low noise/leakage caps from the others so I dont end up putting in the wrong type?

Buzz
 
Look for these designations: CSZA, CSSA and CEANL in the part number list in the service manual, Mark also has them listed in his parts list. Read the PDF's in this post, it'll help you understand the designations. http://audiokarma.org/forums/showpost.php?p=3012505&postcount=11

The replacements for low leakage caps are either Nichicon KL, they show up in Mouser as UKL, or Panasonic ECQ film caps for anything under 1uF.

No, the 9500 I own is a SA-9500II, but I have the service manual for the 9500 and I never know when one will cross my bench, so I have prepared one in advance. I've done that for most of Pioneer's stuff, since I have most of their service manuals and the manuals are pretty reliable.
 
Thanks for sharing your list. That helps out a lot. I have found several replacements for the 2SC1451 in other posts from Mark. They are KSC2310 and KSC3503ESTU. Maybe he will let us know what works best for the Preamp section.
 
i have used both. successfully

KSC3503 will not have any possible heat issues

awh-041 vr1 10k multi offset
awh-041 vr2 10k multi offset
awh-041 vr3 100 single idle
awh-041 vr4 100 single idle

652-3296P-1-103LF

652-3386H-1-101LF

multi for offset for ability to finely set, single for idle because you would end up cranking forever to get there.


as for the two on the power supply board I believe they adjust UP perpendicular to the PC board.
 
Sorry, I completely missed that, I even mentioned it in my list and still didn't get what multi offset means! :withstpd:

Just placed an order for this BOM - thank you for making this so easy. The only part that was "backordered" was 512-KSD1616AGBU the rest are on the way!

512-KSD1616AGTA

actually: 512-KSC2383YTA although many parts lists haven't gotten updated.

should have spoke up sooner...

I just used Matt's BOM since I haven't done this before and made up a project for the SA-9500. I deleted the B/O item and replaced it with the one above. Nice easy way to get a project build list at Mouser. $48 in parts...today's prices is reasonable for a 'new' SA-9500.

Thanks Matt

thing is, lists are STARTING points, where each is to be visually verified as present and the SAME value before ordering...

I have done several sa-9500's, and have one of my own waiting for some TLC...
 
For the protection board, MattSD lists replacements for Q6 & Q7 but what about Q1-Q5?

awm-074 q1 2sc869
awm-074 q2 2sc869
awm-074 q3 2sc945
awm-074 q4 2sc945
awm-074 q5 2sa733
awm-074 q6 2sc945
awm-074 q7 2sc1384

AWM-074: Q6: 2SC945: 512-KSC2383YTA
AWM-074: Q7: 2SC1384: 512-KSC2690AYS

If I'm in there replacing the transistors, why not replace them all? Just curious as I'm a noobie.

Thanks,
Michael
 
q1 - q4 ksc1845
q5 ksa992

(look ^^^^ up)

until you have the transistor replacement layout thing down pat,
compounded errors just make it harder to get working,
when the need for replacement hasn't been proved.


Q6 and q7 HAVE been proved.
the 945 and 733 transistors come in ecb and ebc flavors - making their identification during replacement(mandatory) more tricky.

So, I was finally getting around to recapping my SA-9500. The filter caps I bought are screw type (but they do fit into the space perfectly) where the original filter capacitors have twin posts to which a number of wires are attached (both soldered and wrapped as far as I can tell). I probably could, with much care, manage to detach, and then re-attach to my screws, but wondered if there was a better way? Possibly even trying to sever the twin posts from the old caps so that I could re-attach the posts rather than each individual wire? Any help would be greatly appreciated.
