I have a guy locking at it that service the new Phoenix gold amps. Does any of you have the schematic for the mq430 or is it possible to get hold of?
It has som kind of noise in the channel thats not working right and he might need the schematic to now what to look for.

The right channel puts out about half the power of the left and if i measured as if bridged it shows the same as for the left channel. All this in stereo mode, if i put it in bridged mode it works as the front part and both channels at the same level just mono signal and dubble as bridged. Could thi...

I say the difference was pretty clear on most of them. just as Eric said the PG and the Rockford are some what close, the other ones sounds more dull in comparison. Then again I'm going to put the RF Prime in my car so non of them sounds bad, just not as good as the PG ones. I am a bit of a hifi ner...

enough to notice. did not hear it when i tried the front channels.

Hi. I have tested a few smaller amplifiers from a few different brands and still think PG amp sounds clearer than the others I tested. It is of course subjective , but it has nothing to do with the brand. The others sound great but not as clear in my opinion. Amplifiers in question is. PG MS275 PG M...

Hi.
Just tested a MQ-430 and the right rear channel sounded lower in volume than the left.
So is there a trimpot or something that can fix this? if so where is it? don't want to mess with the wrong thing.

Thanks.

Have ordered the fets and the resistors. I hope i can fix this now.

Is it possible to measure them were they sit or do i fooling my self. Did try and got about 47 ohm´s.
I know it´s cheap stuff but don´t want to mess with it if i don´t need to.

As i understand this is the resistors but they are 47ohm resistors if i´m not wrong here.

Thanks for all the help so far.

I try again. is there anyone here that can point out the gate resistors for me. Not that in to electronics but i think i can replace the broken parts if i know what parts to replace. Thanks

The caps are now replaced and the amp is working fine.

Thanks Eric

I guess it´s the caps i marked thats need replacing.
in that case i think its already done.

Hi.
I´m planing to recap a M25.
What capacitors should i change and what is suitable replacement?

Thanks.

Got my M50 from him and it worked great and i got it fast.

Bought a ms275 of him and I'm very happy.

Thanks guys. Can you point out the fets and the resistors in the picture it would save me a lot of time.

its open.

I have a mps 2240 that i open up today to check the caps. I never tried it after i bought it so i didn't realised that i had a bad one. So one of the "lines" in the board is burnt of as you can se in the picture and what i want to know is it possible to fix this with a little wire and what...
