Does anybody know who can fix these? I need a new power supply.

As long as the board is not burned up any so-so tech can rebuild the power supply. Its just mosfets , drivers, and gate resistors normally. Not really a big deal unless you get a ding-dong that can't follow the simple rule of replace the parts exactly.

NOW, by my experience about 90% of the time you will have blown outputs along with the symptom of a blown power supply. The only time I have seen just a blown power supply was in single battery none stiffened 12 volt systems... But maybe your lucky and the supply is the only issue... oh and yes I have done this before

Have you given PG/Rodin a call to check there rates ? I'm a bit out of touch with them myself, but they used to a pretty good option in the past,,, But I am not up to date on their current status service wise... But they might be worth a try.
I would go that route if I wasn't inclined to do it myself like I am....

pg is outsourcing repairs now and the price is pretty high....better off finding a guru on the forum...there are a few who can pull it off on here and it would be cheaper then pg these days.

so do you generally just look for burned components and follow the tracer path down to see whats what? I have a few amps that I am really tempted to do myself as it doesn't appear to be power related...signal issues and found a bad transistor...

You might want to contact PG regardless, to figure out what their Canadian repair center is.

They changed Canadian distributors only recently, so I wouldn't be surprised if the repair place moved as well.

I was told they would be out-sourcing the repairs about a year or so ago by a insider at the time. I was not sure if they had going that way.
recently they wanted to charge a friend of mine $270.00 to repair the frontend board of his TI-900.7. Nothing wrong with any of the amp channels just a shorted op-amp on the RCA board and they quoted him $250.00...For that kind of money I could almost rebuild it from ash's

...
But I already have a few favors coming in I need to take care of them right now, so it would be at least a week or more before I could even consider taking in anymore work.
I got backed up a while back and I don't care to do that again, I hope you understand.

Plus your customs people like to take advantage of its citizens. the last repair I sent back to Canada the client had a $60.00 tax charge from customs even after I repacked the amp in the same box it came to me in and with all the original paperwork from its Canadian origin...< double boxed of course> The client wanted me to supply extra paperwork for a customs dispute that should have never happened in the first place... Just a big pain for him and me also as I was disturbed by the fact that Canadian customs would do such things to their own citizens.

As for tracking down the damaged components, its pretty simple really, but if your not used to doing it and lack the proper tools and training and experience it could become a nightmare.
I have a fairly long history in car audio repair, especially amps so it something I can do almost half asleep. Its actually a bigger pain to take apart and reassemble then to to repair, once you have done a few dozen...Also the time required to re-qualify the amp to spec is also never really talked about by anybody, and it does take time to burn in and retest the amp to spec for reliability.

Most likely you will need to replace all the power mosfets, all the gate resistors, and all the driver transistors for the gates.

Q61 & Q63 & Q78 & Q80 are A06 transistors
Q62 & Q64 & Q79 & Q81 are A56 transistors
R325 thru R332 & R371 thru R381 are 30.1 ohm SMD 0805 1% tolerance resistors.
You will need to check R22 and R61 and R62 and R437 for open condition, they should read 1 ohm at 1% tolerance 0805 size.
Power fets:
Q65 thru Q72 & Q82 thru Q89 are the power mosfets. I have seen RFP70NO6 devices used here mostly. upgrade devices would include the following IRF part numbers IRF-1010 and IRF-3205. I have all of these and they may be found using the links below to do global parts search worldwide:
You should get +&- 40 vdc rail supply and +&- 50 vdc Aux supply along with a clean stable +&- 15 volt supply for the frontend board.

This amp has dual power supply's and is configured as a left and right sided design, so there is a left Aux and rail supply for the left side of the amp and a right supply for the right side. only the +&- 15 vdc rails are derived separately one from each side I.E. the left supply has the +15 supply and the right has the -15 supply. So both supply's must be working for the frontend to have balanced DC voltages present and or course proper operation.

Either link is helpful but i use both as needed....hope this info is helpful to you.

I've been doing the PG non-warranty repairs at PG for the past 6 weeks. The flat rates haven't changed.

They changed in 2008 sometime....

I believe it USED to be around 125 or 150...(can't remember) to repair 900.7's....

now its almost double.

I sent in my 400ZXTi last August because it was going thermal in only a couple of mins. Obviously something was wrong, they repaired it at PG as I talked to Phil and someone tech with a European type of accent about it. I paid somewhere around 120.00USD as far as i know you can still phone the tech department, get an RA and send it in for work. As far as rates they are what they were last year according to the web site i looked at last week.

( Shakes his head at PG's rip off rates )

You can buy a ZX400Ti BNIB right now for $200 shipped

so what.... doesn't matter too much to me. i was only stating what it cost me. they also gave me brand new windows for the 400 and 450 and a conversion kit for my 450ZX as well(the fan and resistors). to make it a V.2 these things i paid nothing for. i know it was repaired properly and it's only 120.00 dollars.

Did that include shipping ?

Or parts ?

Or labor ?

you should read the fine print on the new " flat rates "

Stryker · Post by **Stryker** » Sat May 16, 2009 5:49 pm

at the time it included everything: parts,labor return shipping. i don't know about now only what it cost me last year.

REFURBISHED AND REPAIRED ELECTRONICS
HAVE A 90 DAY WARRANTY.

FLAT RATES DO NOT INCLUDE THE COST OF COSMETIC PARTS, CIRCUIT BOARD REPLACEMENT, MANUALS / LITERATURE OR REPLACEMENT OF ORIGINAL PACKAGING MATERIALS.

UNITS WITH CIRCUIT BOARD DAMAGE, MODIFIED UNITS OR
WATER / FLOOD DAMAGED UNITS WILL NOT BE COVERED UNDER THE FLAT FEE PROGRAM. THESE UNITS WILL BE EVALUATED AND A QUOTE FOR REPAIR WILL BE GIVEN.

IF A UNIT IS RECEIVED THAT IS NOT COVERED UNDER THE TERMS OF THE FLAT FEE PROGRAM AND THE CUSTOMER CHOOSES TO NOT HAVE THE UNIT REPAIRED, THE CUSTOMER WILL BE RESPONSIBLE FOR ALL RETURN FREIGHT AND HANDLING CHARGES.

sounds like some pretty standard fine print to me. I wouldn't say those limitations or flat rates for repair are unreasonable either. Parts and labor for a repair on electronics has nothing to do with the current asking price for the equipment on ebay. It may very well affect my decision as to repair or replace, but I think PG offers a fair price for good service. In fact I think it's a steal for factory service on just about every model or item they ever produced over the last two decades. What other manufacturer even comes close to that level of service?

thats all I was trying to say....just saying what my experience was and it was good. they had my amp back to me fairly quickly and threw in some extra's when i told them my fan in my 450ZX was missing a few blades and needed new windows

All I'm saying is you don't even want to know how cheap that was to do.

What I'm saying is the actual repair costs....are much lower than the rates they are charging....at their repair rates....I would be more inclined to buy a new amp.

I hear ya. Some of the rates on the less expensive equipment can definitely make someone consider the cost effectiveness of repair. At the same time, I would fully expect for their expenses related to a repair to be much less than what they charge. Just because someone profits from providing a valuable service doesn't make it unfair to the customer. We all have to make a living. And in this case, it's a technician that knows PG equipment like the back of his hand and provides a very valuable service to all of us who love Phoenix Gold.

dBincognito · Post by **dBincognito** » Sat May 16, 2009 8:18 pm

You would also have to take into consideration....the whole win some/ lose some.....I'm sure they don't profit from every repair.....and any profit only helps to keep the company alive.....I'm all for it....but I think at the rate on the 900.7...I might lean toward a new RSD....and sell the 900.7...or see if I could get it repaired by someone in here.

Stryker · Post by **Stryker** » Sat May 16, 2009 8:53 pm

lol..... i wouldn't have a clue how to do what they did to my amp. i also still have the fan and resistor in a bag cause i don't wanna F it up and it came with instructions

. i think i got my money's worth in some ways

Hi Roland, I have sent you a PM......C

I have never in the past doubted PG's repairs or policies. In fact I use them to set my own rates by in the past.
To my business knowledge PG has had very fair rates, as do many other companies. this fair rate policy is based on a desire to build customer loyalty in the product lines and to keep past customers happy and satisfied in a way to promote positive corporate growth.
So I have sent you a PM with a cut and paste of the email Jennifer sent my client.

So maybe this is all a mistake, If so I have sent you a apoligy in the PM, and I am making one here in public also.

Perhaps we can work this out as my client may still want the amp repaired, and my time is very limited currently.
I have looked at the amp and disconnected the frontend RCA board ribbon cables and the amp fires right up and has all of its proper rails. And if the frontend board is connected back in circuit it faults and one of the 15 volt rails drops to like 3 volts, indicating a shorted frontend board issue.....
I do thank you for your response and any headway we can make in this matter...kind regards Cecil

Also for what its worth some of PG's amps are a 'Time Sink" to repair. Especially the show quality amps. There is a huge amount of time required to maintain cosmetic quality in one's workmanship on these amps. Or the entire purpose or restoring one of these amps is shot out the window.
PG has always made some of the finest looking amps, both inside and out and when a tech works on these a ton of attention must be given to detail and quality craftsmanship.
I myself have spent many hours above and beyond the repair service just trying to maintain the "good looks" of PG amps.
Like I said in my prior post ' You will spend more time taking the amp apart and reassembling it properly and cleanly then you will likely need to actually repair the amp"

I did not mean to stir things up around here. if I did so then perhaps i can get it straightened out
