Thanks Chester. The SX seemed like a good deal, but I didn't know how newer amps stacked up against the old school stuff I'm use to running. I'm also waiting to hear what mods Mr. Mantz did to the 2 RX's.

After getting a MS-2125 that needed repair, I've been learning about PG amps. I was offered a brand new SX1200.5 for $185. All I know about it is that Mr. Mantz(Zed Audio) designed it for PG. The seller also has a RX500.1 and RX400.4 modified by Mr. Mantz for $250 for both. How do these amps rate am...

Thanks a lot guys. I've been reading all the threads I can find and watching youtube videos. I'm really enjoying learning and appreciate all the advice from members. I love the custom build threads members have on here as well. The only problem is I'm getting addicted to PG amps!! lol I have about 5...

While researching and trying to learn as much as possible, I found vwdude's list of parts in another thread. He recommends Nichicon UHE1C822MHD's for the caps instead of the Nichicon UHE1C562MHD6's. The only difference I see in specs are the MHD's are 8200µF compared to the HD6's 5600µF. Besides bei...

That amp is well worth fixing. The repairs should not be too difficult. PG boards of this type are easily damaged with too much heat from your soldering iron, so keep that in mind. You will need to replace the 12 power supply input capacitors, as yours are leaking. You will also probably have to re...

How do I measure the transistors correctly? Each side has 044N's but they have different smaller numbers below the IRFP044 on each one. What's the Panasonic number for the caps? From reading, it seems they have a much longer life. What would be the replacement parts for the SF302 and SF302A? Lastly,...

I sent you a pm about the Buss bar. If I can afford it, I'll take it. Let me know what you need for it.
Thanks.

Thanks for the input Eric. I'm glad to hear it can be saved. I'm a huge fan of old school car audio and on a tight budget so fixing the amp myself would be awesome. I'm curious, I couldn't see any fluid by the caps. How can you tell mine are leaking from the pics? Or are you just assuming that becau...

Other than 3 of the 4 Mosfets being burned and the ground bar, I couldn't find any other damage. The SF302 and SF302A don't look damaged but I defer to the experts here for advice. I essentially got the amp for free, so I don't mind putting some money into it if it can be fixed.

More pics.

I'm new to the site and amp repair in general. I'm looking for some advice on a MS-2125 I recently picked up. I have a bunch of old school MTX Thunder series amps(2300, 4320, 4160, etc.) and some need repair so I was looking for cheap used amps to learn on. I got lucky and bought a MS-2125, a Kenwoo...
