Re: MS2125 Capacitor Rating Question
still no reply for Altser. Ive emailed and left voicemails. Anybody know where he is? Im moving soon and dont want these amps to get lost in the boxes, Id rather send them out and know where they are.

Re: MS2125 Capacitor Rating Question
Another update, just sent an email to ALTSER about taking a look at the amps to give them a clean bill of health. The Orion HCCA-D2400 I had running the subs now has blown a few FETS, and its a craigslist buy, so definitely out of warranty. I might be sending all 3 in. Thats gonna be a heavy box

Re: Whats the deal?
or someone took a nice top cover off a broken EQ and put it on that one that might have been damaged. I have an MS2125 that has second gen (with master/slave ports) on a gen3 PCB, so I have 2 empty holes on my endplate. Came that way when I bought it. I agree with wooferdog, use the diagram to make ...

Re: isolator questions
not sure if someone said this already, but ive never liked the diode based isolators. They have anywhere from .5 to 1V drop across the diodes, and get very hot under high amperage. I have always used the PAC-200 solenoids to switch batteries on and off. You can run as many as you want in parallel. I...

Re: Stickers, Logos, and Emblems
Im not really planning on mass producing them, but if guys want one for a back window, plexi, or install Id be glad to give them a good deal on a couple. Most of the files I have are older, and Im always looking for other variations and clean pics of all the PG logos. Im working on digitizing the en...

Re: Stickers, Logos, and Emblems
if that was a monochrome image its totally doable. the problem with a picture like that is all the details, and the colors. I put it in my 3D software, and doing it with the relief of dimension doesnt look very good. If it was black and white I could do a simple outline engrave cut and it would look...

Stickers, Logos, and Emblems
Hi all. Not sure where else to put this but if its in the wrong spot mods please move it. I have a collection of OLD PG stickers that are bad, they wont stick anymore, and I need to remake them. I have a plotter, and I have already scanned and converted the old stickers. I know I can make these for ...

Re: Let's see your stash
Figured Id show what I have. An MQ430, Ill have to get the Serial Number later. 2 MS2125's. One is a REV C1, and the other is a REV E. Serials 213075 and 214708 respectively. I bought the REV C1 off a work buddy about 8-9 years ago, who about 15 years ago found it under a work bench at a shop he was...

Re: MS2125 Capacitor Rating Question
I only powered the amp up momentarily to make sure there were no big issues before I put the sink back on. There was no load hooked up, or inputs. none of the fets or transistors got even warm to the touch. The ones that did get hot were in the middle of the board, on the input stages. The voltage c...

Re: MS2125 Capacitor Rating Question
UPDATE! ok the amp idle current was reading off. my crappy meter on the power supply was around 4A (analog 20A meter, no numbers), but the Tektronix said 1.4A give or take. I had 2 bad vias on the input caps, all fixed now. The 5W 620 Ohm resistors at R345 and R346 are getting extremely hot after ab...

Re: MS2125 Capacitor Rating Question
Eric, thanks again for all of your info. I got all the caps done on the 2125, the 4 rail caps, and the 12 input caps. I also replaced the 2 resistors with 5W models. All I could find in that big of a value were wirewound hopefully that wont make a difference. I got the amp fired up without the sink ...

Re: MS2125 Capacitor Rating Question
Eric are you talking about the input caps on the MS430 or the MS2125? The caps on the MQ arent leaking, but are still the original 2200uF units. Should I just do them anyways?

Re: MS2125 Capacitor Rating Question
Eric, I took the stickers off the caps on the MQ-430 and they were just bubbles. I wasnt sure if the caps were vented on the top or just the bottom. Since none of them are leaking I will close it back up and plus it back in. Just ordered the caps for the 2 MS2125s from Digikey. Cant wait to have my ...

Re: MS2125 Capacitor Rating Question
ok so ive been mistaken, ive had my speaker amp in the yukon for so long i forgot that it wasnt a MS275, but its a MQ430. I pulled the bottom cover off and all the caps look great, no leaking. They have the same 220uf 16V input caps that the 2125 has, is it worth replacing them now, or should I leav...

Re: MS2125 Capacitor Rating Question
well i tore down the amp the other night and it looks like someone has been in this particular amp before :-(. take a look at these pics. there is a bunch of corrosion and what looks like melt marks or arcing marks on the plastic insulator. 2 of the pads on the bottom side of the amp by the input ca...

Re: MS2125 Capacitor Rating Question
i totally understand your worries about the DIY crowd. This is something I can easily handle, my only issue is finding time. I work 80 hours a week and have a 9 month old at home. What would any of you guys charge me to do this to both 2125s and the 275? I just had the other 2125 at PG about a year ...

Re: MS2125 Capacitor Rating Question
could have been. i never took the bottom of the amp off until i had to fix the buss bar issue the first time. Im going to get some copper bars and try to make some like the originals, i dont like the 4ga jumper i did to fix it originally.

Re: MS2125 Capacitor Rating Question
these amps have never been lower than 2 ohms, and i dont beat on them. they have 2 120mm fans pushing cold air directly on them, and they have never gone into thermal shutdown. I am VERY experienced with electronics i just dont happen to have schematics for this amp, and there has been maybe some mi...

MS2125 Capacitor Rating Question
Hi all, been a long time follower of the forum, but a new member. I have 2 MS2125 amps, and an MS275, and absolutely rave about them. One 2125 is in my theater, running 4-12" subs in a big ported box, running on a 50A power supply and supplemented with 2 kinetic batteries. The other is in my Yu...
