Hi ! I'm french, so I hope you'll excuse my english

We purpose to me a Phoenix Gold MAC 200, so I don't know this amp and I like to know if it's a good amplifier to plug with a MB Quart PSD 213 component.
I'm looking for quality, both dynamic and clearness.

Is this a good amp for this use ?

Thanks a lot 😉

PS : I've mailed Phoenix Gold to know the difference between a MAC 200 and a MS, that's their answer :

"The amp is a great unit and will function well for almost any moderate power purpose. I do not have a manual for the amplifier that I can provide you but if you look a the dimensions of the unit and compare it to the same size “MS” chassis amp, it is the same unit with a different power supply. The power supply in the “MAC” is optimized for 8 ohms vs. the 4 ohm rating of the “MS” so the 4 ohm rating of the MS amplifiers would be the same for the MAC except at 8 ohms instead."

Interesting answer they gave you denis. I love it how PG are so honest, its great!
Here is the manual for this amp:
ftp://208.187.38.55/Phoenix_Gold/Manuals/Amplifiers/MS_MAC_Amps/

and yes I think it would be good for those MBQ components 😉

Is it important ? What's difference between 8 ohms and 4 ohms power supply ?

Its important but it will be fine for your speakers which are 4 ohms. You cant bridge it into 4ohms or use it as 2 ohm stereo 😉

M50

I was wondering if anyone had the schematics availible for a Phoenix Gold M50.

Here is the amp I am currently working on... an a/d/s/ P640, 6x40 or 2x120 and 2x40

Motorola 1302a and 3281A to-247 output transistors, 8xNDP7060 Power supply FETs, bandpass and high pass active crossover network built in...

perfect for a 2-way active setup, bridge channels 1+2 and 3+4 for mids, and use 5 and 6 for tweets.

I have an M44 PHoenix Gold that I was working on and while I was un sodering a bad resistor I accidently ripped a trace on the left side of the resistor to the right on the picture shown.If someone could post a better close up of the area it would help me greatly because I cant find where the trace origianlly went.I was using a battery operated board sodering iron and apparently it wasnt hot enough.I have searched and search and havent found any good closeups of this board.This is still my favorite amp even though I have newer ones.

What I need is a closeup right in front of the two big blue capacitors.In front of the right one to be exact.None of the closeups for M44`s I found didnt show this area.

upping an old thread...

I recently repaired this amp, took some pics and I just had to post this.
