Pioneer sx 3600 eletronics replacements.

[Mrcoolest123]

Good day everyone!

This is my second time asking for guidance on the forum, and I hope you all can help me to some degree.

My pioneer sx 3600 receiver is having problems. The phono left channel is dead, and my mono switch is broken.

I suppose the problem lies on some capacitor or resistor that has gone bad after all those years, (and exploding the main amplifier cap by powering it on 220V when it was supposed to receive 110V two years ago when i got the machine may have accelerated the problems) , so i decided to do a full replacement on the components of this unit.

I already read the service manual and i'm relieved pioneer engineers numbered all the pieces to facilitate service, but they forgot to put the components electrical values, so that's a problem.

i found an old thread about another guy having problems with the AUX port on 2008, and found some values on there, (which i put under here to verification):

CEANL 2R2M 50 C85,C86 —---- ) 2.2 UF/ 5O V

CEANL 100M 50 C96,C97 —------ ) 10 UF/ 50 V

CEA 100M 50L C64,C66,C77,C102,C103 —------) 10 UF / 50 v

CEA 220M 25L C100,C101 —---- ) 22 UF / 25 V



These are the ones I have values for. I don't know if they are correct, but that is a beginning.

My questions are:

# Is there a way of knowing the UF and V of the pieces by reading the manual ? because at my current understanding i can't see it, and i intend on doing other replacement works soo knowing how to find them would be good.

#Resistors and Semiconductors seem to have a different kind of classification, can i read them too in the manual?

Thanks for spending time helping me.

PS: English is not my main language, so I'm sorry if all my problems are due to a language barrier.

Hello everyone!

I want to give you guys an update on my pioneer capacitor problems.
I found this official pioneer manual series called "turning fork" that give the answer to all my previous problems. So if you are lost like me, give it a look!

But I still don't understand why some caps have an L at the end of the description and others don't. If anyone knows the answer it would help a lot!

Hello, I would like to see a screen shot of one the "L's" you mentioned, however I believe it is a reference to an Electrolytic capacitor. They typically look like cans and in this case would also be called "radial" because the leads come out the bottom. Please know that most of the folks on here have forgotten more than I know and you really need to read this forum and use Google first and then ask some questions. Then be respectful and courteous and the help will pour in, but you have to start to build a foundation so you can understand the basics. Since you indicated this was plugged into 220 VAC I suggest you look at the power supply first.

I suggest creating a new post in the Pioneer Forum. The Tape forum limits the eyeballs on your issue There's also the DIY forum, where the "L" question might find answers. Perhaps you are looking at an inductor?-they are often labeled "L"

Do look for a service manual at HiEngine.com-membership is free and they don't spam. Service manuals are all over the map for documentation. Sometimes the schematic lists the value of a component, sometimes, only C136, and elsewhere in the manual is a list of part numbers with their corresponding values. In most cases, the value is visible on the component as well-for resistors and caps, at least.

Is there a way of knowing the UF and V of the pieces by reading the manual ?

Yes, the capacitance and voltage values for the electrolytic capacitors are shown on the schematic in the service manual next to the capacitor number. The same is true for the resistors although in this case only the resistance value is shown. The notes shown on the schematic provide additional details about the resistors and capacitors used in the circuits that are shown. There are also notes on the schematic that show the types of transistors (industry part numbers) that are used in the circuits.

But I still don't understand why some caps have an L at the end of the description and others don't. If anyone knows the answer it would help a lot!

The “L” in the part number doesn’t seem to indicate anything specific as far as the associated component is concerned.
