Contact PG. They might still have some in stock, but probably not. Still worth a call or email though.

mq430 gain potentiometer

Post by The Golden One »

thanks for the response i read some where on the phorum there was an upgrade for those potentiometers. but no one elaborated on that so i will probably check with phoenix gold.but the new tech guys arent the best of help maybe there not as experienced with the older amps. thanks

The upgrade is for the x-over control, not the gain or bass controls (or so I have determined from all the PG amps I have owned).

mq430 potentiometers

Post by The Golden One »

i wonder would the upgraded potentiometer work for the zpx2 my sub out adjustment is in sad shape. i have to turn it back and forth and then hope for some sort of output. not good when setting things up because it goes from no output to weak output to maybe full output. just wondering

If they are the same as the input/bass pots in a MS-amp, I have a few new ones in stock [bought from Phil at PG].

They are the same as any MS amp produced later than the grey series.
These pots can be adjusted by hand, as where the grey series-pot are bigger in size, and adjustable only by screwdriver.
I replaced these bigger ones frequently by the smaller ones, using newer endplates.
They both fit the boards of any early, and later models MS amps.
How many do you need?

im thinking the gain and bass ones are the same well i know they are on the 430 how ever not sure about the 450. as some amps bass knobs are half slotted that wouldnt make any difference except for in the dark adjustments.i wouldnt want to dip to far into your supply but i may need as many as 12 but what ever you could spare.also moms would have to help me out on the transaction. shoot me a price plus shipping u.s thanks alot.

did some more in depth research on the net on potentiometers thing is i would have to buy 1200 of em for the ones i need.i guess if i did that i would have a life time supply of em come to think of it a life time supply for several people.also it seems that different board revisions like rev g 275 has 50k for gain and a half sloted 10k for bass same for rev c 430 but for the rev b 430 there all the same ecept no rating they all say 103b pa then one odd ball says 103b ya just to add more to my confusion.

I only found three of them, so I'm afraid you'll have to find some other source for those....1200 is a awefull lot!
Will check over here if there is a replacement available.

well thanks for trying who knows maybe something will turn up ive not given up yet.and you may need those for something else i have a feeling some things will only get harder to find for these amps.as the people that built these amps are doing there own thing or are they maybe there just in the background watching our every move.

its really not so simple as just those 50k and 10k ratings unless they were sourced form phoenix gold. because if you try to enter the guide lines in on the order chart on some sites there are like 10 different factors that they ask for.the stuff they asked was way over my head it seems like only enstein could figure out.
