Hi, my name is XXXXX XXXXX will be assisting you today. I am a Master Technician that's dedicated to giving you the best Answer possible.

If you are new to the site, this is briefly how it works:

1. We will go back and forth exchanging information (if needed) about your problem until we're finished.
2. I will only give you the best possible Answer for your problem without the ability of actually being present with you.
3. Understand that I am a real hands on Master Technician and fix these issues everyday in my shop in FL.
4. Remember to leave a Positive Rating after we're finished to compensate me for my time just like you would at a repair shop.

* Favorable outcomes are always desired, but are sometimes out of both of our control.

I see that your Question is several hours old and am inquiring to see if you still needed help with this or want to cancel. Thanks

Remove the Speakers and see if it still overloads.

Check the ohm rating of each speaker. If there where there suppose to be, the amp is most likely back in it. There's removable transistors in the amp that get weak and overload over time. There should be 2 per channel and are screwed into the heatsink on the amp. replace them all at once and that should fix your problem.

It's not very hard to do. Just has to be done correctly. You'll need the replacement Transistors and thermal compound to reapply to it. The transistor's have to go in the same way they came out since the two pins are different. I'll need to know the part numbers off the transistors. There should be 4 of them total and 2 per channel. Both Channels use the same 2 transistor types.

Example:

Left Channel: Sample1 and Sample 2.

Right Channel: Sample 1 and Sample 2.

The Transistors look like this:

Let me know the part numbers and I'll locate the cheap replacements for you.

We're not allowed to communicate outside of this Q&A Thread my friend.

Can you take a picture of the inside and upload it here? Sometimes those transistors are hidden by a sliding cover.

I'm trying to locate a picture of the internals of that amp, but not having much luck since very few of them survived the years. I've worked on 100's from that time frame and they all had those style transistors. I'll attempt to continue searching for a picture to better help you on this unless you have an Electronic Repair shop nearby that can point the Audio Output Transistors to you. It should take them all of a minute to do so. From there, you can give me there part numbers and I'll locate the replacements for you.

These systems use crossover's that make the standards of normal speaker wiring completely different than the norm. What was the ohm reading from each speaker? If one reads a near short than that can cause the overload to trip red. Let me know what each speakers ohm ratings are by using a multi-meter.

200 OHM setting is ok. We have to test them out of circuit so remove one of the speaker wires on all speakers then test them. Otherwise, we'll be getting false readings from the crossover and amp circuits.

Ok, look on the back of each speaker. It will tell you what Ohm Rating they are. i.e. 6Ω, 12Ω, 16Ω, etc. What are they?41098.8619111921

Ok, all of them are reading good except for the 10.1. Disconnect that one and see if it continues to overload.

Sorry for the delay. Yeah, the amp's needs work done on it. It's not the Speakers or Crossover's. If you can get me the numbers on the transistors, I can help you order them.

Sounds great. You can send them to experts@pearl.com and they will forward them to me. Let them know that it's for Carl L.

Ok, I'll let you know when I receive them. Haven't gotten them as of yet.
