X1200.1

444 FED · Post by **444 FED** » Tue Apr 03, 2007 10:54 pm

Well I recently made a trade to aquire an X1200.1.

Well tonight at work I placed it on the bench, connected power, and at least expected the power LED to come on. Nope, it did not.

So I thought maybe on some off chance that the LED was burnt out, opened it up, and checked for voltage at the LED connector, nope, nothing.

When I power the remote connection I get a small click out of the amp, it seems to be the small relay between the power connectors and the control board.

On the output I only get some mild "static" as best as I can call it, when I connect or disconnect a speaker with it "powered", which through some circuit tracing almost seems that the aforementioned relay is connected to the output stage.

Now what I was looking for was a schematic of this amp, since someone has already been into this amp and have "repaired" certain parts of this amp, which from what I can tell, looks to be all connected to the correct points. There are a couple burnt traces, one being the trace that would be the feed back to the relay, there has been a jumper wire added here.

I can't see any obvious problems.

Anyway of getting the schematics for this amp? I really need to decide if this amp is worth attempting to repair, otherwise, I will want to reverse the trade, and I don't want to leave it too long.

TIA

PG does not release prints, Sorry. They go to a fair amount of trouble to support your repair needs.
Just go to their website and look for support and then under warranty they list current flat repair rates which include return shipping, unless your outside this country. Call them with a debit card and they will issue you a RMA#, and give you there return shipping address to the repair group. There prices are very reasonable. I know because I charge a fair bit more so I can pay my building rent monthly.

I am very familiar with the amp your talking about myself as I tinker with amps everyday at work. The hardwired trace you describe sounds pretty horrible. I would reverse the deal, and keep looking for a new amp or a better deal.

PG can just about fix anything but when a amp has been abused like you describe yours to be, well my common sense would say put it back where it came from and keep searching.

I wish you well on your quest. Please feel free to pm me if I have left you with any burning questions.

Happy Trails

Yeah I read about the lack of schematics being released in another thread, but was hoping that rthere was still away to get them.

I just wanted to be able to provide my repair tech with them, so he would look at this amp almost right away, if he had them, he doesn't much like reverse engenering, which is understandable, I don't really care for it either.

I was also a bit disapointed when I saw the "repairs".

I don't know that I want to reverse the trade, well I do, because then I would have my brand new working amps back, but I haven't seen one of these around before, and would compliment my Xenon front amp well (I have a few, 100.4, 200.2 100.2 or a 200.4, depends on which one I decide to use.).

I'll check the PG site and see what's what, but I don't know that I'd want to spend a few hundred dollars to repair it.

Welcome to the Phorum.

Pity about your amp. The X1200.1 is a real beast; if you get it working I'm sure you will love it.

If you're going to do anything with it, look for cold solder joints. This was an issue on a bunch of the early model Xenon amps, which they later improved the QA on. This was fixed under warranty for most people, but because many of the amps were leaked to the eBay grey market, quite a few went without being fixed.

Flat rate is $135.00 shipped back to you, I don't know of any cheaper way to keep your amp running. Its a shame you traded for a abused piece of equipment. I own three Xenons, and I can fix my own. I bought all three broken, and so far I'm just out some time on getting them running. And man do they all three run.
Total cost so far is about 17 cents to repair my three, but it does take a bit of time on my part to completely go through one and set it up the way I like them to run.
PG should be able to take care of your needs. If I wasn't so inclined into electronics i would send everything to them. but I do this sort off thing everyday for a living, so its all good to me. After 20 + years its just another day at the park.
Good luck on your amp, PG really is your best bet.

They won't ship back to you being in Canada. Repairs here are done by Trends, who haven't been fantastic when I tried to get my powercore fixed a few years back. Who knows, maybe they've changed. Worst case is that PG ships to someone trustworthy in the states, and they ship to you. This is how I get all of my repairs done now. There are many of us on this forum that would be willing to help you out, if you decide to go that route.

Bump for me,

If for some reason you do not get your X1200.1 up and running I happen to have a BNIB X600.1 left in my arsenal that I am trying to part with.

I do however concur with contacting PG for service. Also note that certain revisions of the X1200.1 had a pop delay circuit mod which did include cutting a trace and adding a jumper wire, but there should also be a small "daughter-board" circuit in the corner opposite the speaker terminals. If this does not sound like what you are seeing then it is likely a hack repair.

Im very tempted to buy that last 600.1 for a few years down the road

824 watts for $250 is peanuts

But I have no more moneys

I called Jason at Trends today and chatted for a while. He said that I could send it to them, but it would go to PG in the States anyway for the actual repair.
I think I would hate to send it to them and have them say they won't fix it for me, without replacing the circuit board, because I can guarnetee you it's a hack repair. There are definatly two burnt traces, one "repaired" with a jumper wire, that is actually made from two other wires.

And another trace re-made from solder.

I think I'm just going to go back and get my amps back, as long as they will trade me back, which I can't see them saying no. If they do say no, well then I'll fix it somehow, maybe time to learn how to diagnose and repair the internals.

So now I just need to see what happens.

If I end up keeping it, well I'll defimnatly lean on you guys for some help in finding this myself.

Thanks.

I'll see what I can do if I have time, before tomorrow.

Fed if you can get it to work, then that would be an awesome amp. You won't be disappointed.

Well I took it back and reversed the deal. I got my X200.2 and X100.4 back.

He then offered me the amp for $200 as is. It's tempting, but I don't know what exactly is wrong with it, or how much it's going to cost to get it working again.

I've sourced out a couple others for not much more, but shipping would add considerably, that are guanteed to work, they have been previously repaired as well.

On the flip side, I mentioned that my repair tech could probably look at it and get it to work. He seemed interested in me getting it repaired for him, but I wasn't able to get a hold of the repair tech when I was at the store.

I'm really tempted to just buy it for $200, but it just seems wrong to buy a known broken amp that will not even turn on.

If it would at least power up, that would be a different story.

Sorry no pics of the "repairs", I didn't have time to take it back apart again.
