Hi all,

Could anyone point me in the right direction? I am looking for JBL S64AMI
and/or S53AMI power amplifier for 12" JBL PB12 subwoofer. These amps die
after ~1 year of use and I'd be interested in finding a supplier for them...
If not, then I'll just repair mine, but it would be nice to know if such
supplier exists. Thanks!

Please e-mail: viperz (at) mail (dot) com

The only source that I know of is Harman(JBL). The S64 is currently out of
stock, but they are expecting more. The S53 is in stock. We have many of
the Infinity subs in the field with the S53 modules and have replaced
exactly one, in a unit that was blown up by lightning. Most of the problems
that we have seen have been C6 failures, not bad modules. What makes you
say that they die after a year of use?

If the module is bad, it is an expensive part. How have you determined that
this is the problem?

Hi Leonard,

Actually, looks like I was wrong. I just saw a message in this newsgroup
describing the same symptoms as mine in the same subwoofer. Anyway, I opened
the sub and the schematic of actual amp is different from the one that I
have in the manual. Instead of S64 I have 3 FET transistors with thermister
sitting on large heatsink. All 3 transistors are dead (I don't know what
happened to this amp), plus one of the diodes is also dead. That's all what
I have found so far.
Is there any place where I can get repair manual for mine? On the PCB it
says "Revision C", but revisions of design in the manual have versions in
numbers, not letters.

Also, could you be more specific why that specific capacitor (C6) fails?

I went to Harmanaudio.com website today and it does not show that they have
any parts for PB12.

Eugen.

Actually, checking I find that the c6 failures are not in this model. There
are, however, several service bulletins on this unit. The site you went to
does not have service parts, only accessories and manuals and consumer
replaceable parts. The service site has all parts listed and most should be
available, but you have to be a servicer to have access.

Contact Harman Consumer Group at 516-496-3400. They may sell you a service
manual. They might refer you to a service center.

Little update:
My sub was made in Dec.2002 (yeah, and this expensive beast is already
dead), so service manual is old compared to the sub. JBL dropped IC-based
power amp idea and moved onto FET-based power amp... Hopefully, I will be
able to locate newer service manual now

If it was made in Dec. 2002 it has to be under warranty. Why are you
messing with fixing it yourself? The electronics have a 1 year warranty.

I got mine from liquidators, so I don't think I have any warranty on this
sub.

It's so weird. I asked Harman if they had latest service manual and person
from parts department was really kind to send me a short version of service
manual for free, but... it's the same manual that I have! I mean S64AMI is
in this manual too

I just found out Friday that the S64AMI and S53AMI output modules are

JBL is making accomodation deals to customers on another model sub.
