10 Years of Action!
 
4 Attachment(s)
And my PPI 4125 decided to take a break :( LOL

My Amp after 10 years of "Doing Work" decided it had had enough. A small puff of smoke and she fell silent. So I did some asking around on DIYaudio.com and it turns out their is quite a few guys that still repair these old amp's and "Mod" them in the process. I found a guy that will go threw my amp and fix whats broken and then Update it and Crank it up!!!! As if I needed more volume. He say's that replacement parts are quite common and much better than the originals. Most of the stuff that breaks can be replaced with better parts. Here are some pic's of the Dammage
The Frist 2 are of the Tower amp that smoked.
The 2nd 2 are of the Hull amp (Still working fine) But I figured I would get it cleaned up and tuned up and overhauled at the same time.

They will bench test it and set it to factory spec's or better and provide a output data sheet

How much does that cost? Much less than a new amp?

It looks like a transistor or two in the switching power supply died. Common. If the circuit board traces aren't damaged then those transistors are typically less than $10 each + labor. It's a good series of amplifiers and worth it to repair....especially in the off season.

501's Im not sure of the cost right now. I was told around $200 if the amp need total rebuild.
I picked up a used on from a buddy for $250 as something to have while these are at the shop . So if I can get these re-built and tuned up for under $200 then I guess I'm doing good.

I don't even know what Amp I would go with in the event I had to replace these. They have worked great so far, and not having to re do the amp mount's for new amps and switch wires around for a new amp is well worth the $ to me.

Sent one for repair about 5 years ago...guys were in AZ. They did a great job. Probably found someone that used to work for PPI before ii was sold.

Loved those amps man!!!!

Zapco 1000.4 :) if replacement is needed.

My Amp repair guy is saying Like $125 to repair the amp. That seems more then fair. I can buy another Used one for around $250 so for 1/2 the cost I can have this one fixed up and possibly made better. No Idea on what the cost is going to be to go threw the other amp. Shipping both amps with in California was only $35 so that didn't Drive cost up to much.

Too bad I didn't know about this long ago. I had an Xtant 1001 that I took into a local repair shop. He didn't have the expertise to do anything about it. I paid like $75 for him to look at it and I never ended up going back and getting it. This was easily over 5 years ago, so it's not like I could walk in there and get my dead amp back now.

Sadly, I have a Phoenix Gold V8001 that I bought off CL that was in protection mode from the first time I hooked it up. But I don't think that one is necessarily worth fixing as the equivalent 2 channel that I bought as a replacement was $146 new.

DavidAnalog 10-15-2013 10:27 AM

$125 is about the minimum repair flat rate for an amplifier which is more than fair.

Here's a little history on the PPI.
The original Precision Power amplifiers were very good. However, there is zero connection to the current overseas company using that name. Jeff Scoon (original owner of PPI) and Bruce McMillian (PPI chief electronics engineer) sold/left and formed a new company call Xtant which basically used the same amplifier topology. Again, a very solid product. And again, Jeff and Bruce moved on, the next time in the late '90s to head up the electronics division for JL Audio where they created the JL Audio Slash amplifiers based on similar designs. The JL Audio Slash amplifiers along with Audison upper end amplifiers remain as two of the very best sound quality amplifiers in the mobile electronics industry.

David: Let me give you a little history abut my PPI's I bought them from a store 10 years ago and put them in my boat and have beat the hell out of them. End of Story!
:)

But your story is better Thanks for the brief history lesson, Please tell us why you know so much old school Audio triva!

An old school motor head could tell you which Chevy had a 327/375 with 4-bolt mains and 2-inch intake valves. I can't remember. But as an old school audio guy I recall related trivia.

Here is a pic of the Burnt amp in the middle of its repair. It looks like he did a great job at cleaning it up.
