PhoenixGold Rsd 600.1

[Gossen]

Hi All,

I'm new here but it seems to be a forum that i will like

I am searching everywhere for a service manual / schematics for the PhoenixGold Rsd 600.1 but with no luck

Does sombody here have it? Or maybe a schematics for one of the other Rsd class D amplifiers? (as they should be quit equal bulid)

the purpose of my question is that i have one that has blown the output FETs and i would like to be able to meassure that the rest is OK.

Best regards

PG does not release schematics but you could try and contact them thru their web-site and ask. Perhaps you will get lucky as they have been recently sold off to AAMP out of Florida <aka Stinger >. And the new Stinger/PG lineup is due to debut at CES next month.

The RSD line is fairly simple and straight forward D design. And if you have one blown output there may be damage to all the others. With what they cost, I would replace all if it were my place to be repairing this amp. As I recall they use a IR driver chip and I would be looking at that as a suspect also, as none of the fet drivers IC's are protected when an output folds over on itself....I have been inside every PG amp ever made including the RSD line up but I lack any printed info on the RSD line....Hope this helps some....C

Hi,

I have tried to contact them through the webpage but unfortunately no answer.

I don't think they are using any IR chip for driving, it looks like the FET drivers are build upon discrete transistors MPSA06, MPSA56, MPSW92, MPSA92 and MPSW42. In the same area a TL072CN is used, I suppose this if for the switch frequency?

I will change all (4) output FET's to new 42n20D (same as before).

I have been measuring on those discretes I mentioned above and i'm quit sure that many of those is broken (some i measure as shortcircuit and some as break) but i have problem in finding MPSW92 and MPSW42 any place near (farnell has those but with deliver from USA and this costs 200Sek delivery to Sweden and the transistor costs like 1,4Sek).

I cant find any replacement for those either (and as I understood it, is it not a good idea to replace with other in a Class D amp, correct?)

The history of this amp is that when i got my hands on it one or maybe two output FETs were smoked and two of the big 3900uF 80V capacitors on the rail were also smoked...

Any tips and suggestions on repairng is very welcome.

Best regards

Can you post a good quality photo of the board where the drivers are located (showing the face of the drivers if possible)?

Please tell me if it's good enough or if i should take som new.

I can't open the full size image.

I seems to have some problems with linking, i added new links wich seems to work better (but not full size unfutunly)

[Gossen]

I think its working now, use the link at the right.

The 1200.1 uses a IR chip. This looks just like a Sony D class amp design. I have been able to repair these with just replacing the outputs before. But on occasion I have seen driver damage that required driver repair.
Your location is the problem IMO. Old PG may or may not have a distributor in your country and they require that you go thru them. I have heard that they do not answer support requests outside the US, but rely on worldwide distributors instead. I do not have the document for this particular amp as it was a current release item and PG like other companies likes to keep current market items in house.
The parts your asking about list for 30 cents US, again I am guessing your location might be a possible cost affect issue.

Ok, I wonder why they used different solotons. This amp is acctually a Roadster 66 but after all I heard the mono amp is a 600.1 (and 4ch is a 500.4).
