I got a new amp today.

Re: I got a new amp today.

So I think I'm going to order parts and let someone else solder them in. I'm good with pups and pots, but ya these multi pin things look difficult.

These are what I ordered.
Plus some fuses.

I'll post up the amp working again, hopefully in the next couple weeks.

Cool.

The ceramic resistors not so hard but they need to be done too [ I'm going to keep stressing this ]
The resistors are actually .1 OHM = OR1

Please don't ignore this or you may waste all your effort. I'd explain electronically why but I doubt you'd understand, but it is critical.

If you can't find 7 watt ones , ten watt ones will work.

I was going to congratulate you on your new amp. Maybe I will just hold off for a bit.

Should've gone with the ol' faithful MG100hdfx

I had one of those come through with a blown chip here a few years back

Quick correction . The resistors are actually .1 OHM

Re: I got a new amp today.

Funny guy.

But those new code 100 models suck bad from what I've gathered. I haven't played one myself.

It's crazy how different the guts look today versus the plexi/metal panel eras.

Re: I got a new amp today.

So many questions and options here:

The website that has the modules only has 3 in stock.... F.
I Can't seem to dig any more up from any source. $136 for 4 modules.

OR I could just buy the chips, they're like 11 bucks each and either solder them in myself... (Risky)
Or take the modules to my local music shop guy and pay him to do it. Cheap!

Then if I get it running.... Do I keep it and never trust it and always be concerned about it?
OR sell it off?

I suppose knowing what I now know about these amps, I could just be very careful with it's operation.....

I could sell it off for $200 as a broken amp and still be good with that, the way that whole deal went down...

I do enjoy a challenge and learning more about amps and how they work.

My old Peavey sounded pretty good the other night ha ha ha less headaches for sure.

Some one experienced in soldering would be the go, those multi pin chips can be difficult.The ceramic resistors not so hard but they need to be done too [ I'm going to keep stressing this ]

Is that the new Marshall PC? Does it run Windows 10 then?

GV you are the man!

Re: I got a new amp today.

Yes, from what I've been reading, you can't change anything with power on or kaboom. Which makes the amp worthless in a recording situation ha ha. Or a testing new stuff out situation....

The resistor on the other end was identical to the one pictured, so I assumed the middle one was too.
I can look when I get home tonight

May as well presume it is the same, most likely. They're probably damaged from from previous blowups
Anyway those three need to be replaced too if you do a module fix and they're pretty critical when it comes to correct operation.

Re: I got a new amp today.

So here's what specifically happened when it blew.

I had decided to try my e1 legendary amps in the effects loop.
As I was working with the levels and whatnot on the amp 1 clean channel, I reached around the back and there's a switch/button to add db or -db in the effects loop.
I pushed that button in and snap! I saw the spark from the fuse go, and smelled a burning smell.

Went to hardware store replaced the fuse, (amp apart now on the bench) and plugged it back in and tried to power it on.... Bzzz fuse snapped again and smoke from the two ic units I am pointing to in pix.

Don't know if that tells you anything but that's what happened.

It appears they're really touchy when swapping things around and respond like I described further back. I'm guessing the guy that sold it to you did a fix but missed a few things. It looks like if you change much around while it's on or off, and there's power in the caps [ even after it's been turned off ] , they want to blow up.

It appears if you have it on [ in working state ] , turn it off and change speakers without the power draining right out first , they'll blow up. Also very easy to short the outputs.
