While you were looking for somebody else to do it, LOCAL, I waited to see what turned up.
Now that you are contemplating DIY territory, here I am...
If you wish, you could compile a list of the caps listed in the service manual in the format I have used for so many others and I will list the appropriate replacements from Mouser.com 's (mainly)) Nichicon line.
If you don't have a downloaded service manual, PM me an email address so I can correct that.
Once you have the manual, the parts list is a bit cryptic,
and what I detail below has to be done anyway:
for example on the Power Amplifier assembly
GWH-139 you will find under "capacitors":
CEANL 4R7M 50L C101,C102
CEANP R22M 50 C125,C126
CEA 471m 6L C133
CEA 101M 25L C134
cryptic huh?
the key:
C101,C102,C125,C126,C133,C134 are identifiers for a SPECIFIC capacitor on the schematic diagram, and pc board layout drawings.
Using them you will find (either from the schematic or LOOKING at the board) that
CEANL 4R7M 50L C101,C102 is a pair of 4.7uf 50v capacitors,
the CEANL part decodes to:
Capacitor,
Electrolytic,
A=radial leads (both out the bottom) ,
NL = low leakage special capacitor.
I would list that in the form I have used for many models here as:
GWH-139 C101 4.7uf 50v CEANL
GWH-139 C102 4.7uf 50v CEANL
now
CEANP R22M 50 C125,C126 will translate out about the same:
they are a pair of 0.22uf 50v capacitors,
the CEANP part decodes to
Capacitor,
Electrolytic,
A=radial leads (both out the bottom) , however
NP = non-polarized capacitor.
I would list that in the form I have used for many models here as:
GWH-139 C125 0.22uf 50v CEANP
GWH-139 C126 0.22uf 50v CEANP
getting a bit shorter:
CEA 471m 6L C133
GWH-139 C133 470uf 6v CEA (plain vanilla cap)
and:
CEA 101M 25L C134
GWH-139 C134 100uf 25v CEA (plain vanilla cap)
With that finalized list (where I supply the replacement parts numbers) then "published" here, everyone can benefit.
I have done several sx-3800's, even have one of the shelf that's waiting for the installation (final installation) of a volume control. I even have gone so far as to convert all the small lights in the push buttons (that are SO hard to get to) with LEDS...
The format is (one component per line) started with this in the service manual's parts lists:
CEANL 4R7M 50L C101,C102
CEANP R22M 50 C125,C126
CEA 471m 6L C133
CEA 101M 25L C134
and ended up with:
GWH-139 C101 4.7uf 50v CEANL
GWH-139 C102 4.7uf 50v CEANL
GWH-139 C125 0.22uf 50v CEANP
GWH-139 C126 0.22uf 50v CEANP
GWH-139 C133 470uf 6v CEA
GWH-139 C134 100uf 25v CEA
after which I ADDED the parts numbers of the replacement capacitors, as well as the replacement's value and voltage:
GWH-139 C101 4.7uf 50v CEANL 4.7uf 63v 647-UKL1J4R7MDD ( 50 to 63 deliberate - closest available, 50 was on order)
GWH-139 C102 4.7uf 50v CEANL 4.7uf 63v 647-UKL1J4R7MDD
GWH-139 C125 0.22uf 50v CEANP 0.22uf 50v 598-DSF050J224
GWH-139 C126 0.22uf 50v CEANP 0.22uf 50v 598-DSF050J224
GWH-139 C133 470uf 6v CEA 470uf 16v 647-UPW1C471MPD (no typo, 16 is deliberate)
GWH-139 C134 100uf 25v CEA 100uf 35v 647-UPW1V101MPD (same here, deliberately from 25 to 35)
These are the types of capacitors in the parts list that are part of a recap:
CEA, Capacitor Electrolytic (A) radial
CEB, Capacitor Electrolytic (B) axial leads (counter-intuitive huh?? a "B" for AXIAL???)
.......Both CEA and CEB can have NL or NP following to make it special...
CSSA, Capacitor Solid Aluminum (A) radial
CSZA Capacitor Solid Tantalum (A) radial
sometimes they may use a triple letter, triple number code for something NOT in their usual nomenclature
like ack-035 - the finned tuning capacitor. but SOMETIMES it can be an electrolytic cap that needs replacement, so include them and I will check...
AS A BONUS with my doing this, besides ending up with a spreadsheet of this, I also generate a Bill Of Materials entry block of the parts numbers to be ordered, sparing YOU the need to type in dozens of alphabet soup entries, instead you copy and paste a block of text into Mousers BOM entry feature (free registration needed). like this:
647-UKL1J4R7MDD
647-UKL1J4R7MDD
598-DSF050J224
598-DSF050J224
647-UPW1C471MPD
647-UPW1V101MPD
although I admit this would work, but changes are more problematic:
647-UKL1J4R7MDD|2
598-DSF050J224|2
647-UPW1C471MPD
647-UPW1V101MPD
