Help Identify YAMAHA amp

Junie · 29th July 2011, 06:58 AM

Good morning to all.
Well another digging and found the below amp module, i know it's from Yamaha but I don't know what model it is.
A schematic is very helpful indeed if you can send it to my mail at juni_macs@yahoo.com
Any help will be greatly appreciated, have a nice day ahead folks.

I think it's a Yamaha PC2602 driver board. But you should check if it's true.

Thanks pradigmshift

Anyone got a schematic? I'm planning to use this amp for my JL 12W6V2.

Has been sent. Could you explain JL 12W6V2?

It's a Sub by JL audio, it was installed in my car a year ago.
Thank you very much for the schematic mate.

here's a link of a subwoofer JL Audio 12W6v2 Subwoofers - Car Audio Subwoofers

Nice sub! But if used in a car, it may be better to use a class D amp instead of AB? Idle it will use around 50 Watts...
The boards do look sturdy enough to use it.
With this amp I would use the voice coils in series if you bridge the amp.

This looks to be a mono module, no bridging possible.

The SRBP board will probably crack when used in a car. Also i'd say there is a transistor missing - Q115. You'd also have to build a switchmode supply to convert the car's 12V power into a suitable symmetric supply to run the amp.

I'm planning to use the sub in HT not in car. I don't want to use it in my daily driver car anymore as i'm driving 200km from sunday to thursday and I have three colleauge coming with me too so it's quite heavy to have it in my car.

I created another thread for the enclosure design, please shed me some ideas, many thanks.

Hi jaycee, the missing tranny is 2sc4793, a counterpart of 2sa1837
