Old School First Gen US Amps Merlin 2000wrms MD3D Amp Guts

[the_garynator]

Picked this up a while back, was cool to own an amp that I remember lusting over back when they were new. I actually bought it because the ebay ad listed it as a 3kw amp and didn't realize it was only 2k until after I hit the buy it now button. I figured since it was my mistake, even though the amp was falsely advertised, that I would resell it.

Long story short, sold it on ebay to some kid who screwed it up...he opened a case, I won, the guy sent it back to me for some reason even after I said he wasn't getting a refund. Cost him $25 to ship it back LOL. Either way, turned out he screwed it up pretty bad but I'm hoping to repair it at some point.

19lbs of amp goodness

Now for the Guts

On another note, if anyone is familiar with amplifier repair, I'd be curious what it would take/cost to fix this thing. I'm proficient in soldering on PCBs but I'm not sure where to start as to diagnosing what is bad and finding the parts to replace.

Some pictures I found around the internet, figured I'd add them in here so that most all the information is in one location

14.4v rating Oh well, the capacitor bank looks right on the mark for a solid 2K, I'm sure it's a great amp.

[finkster]

That's a huge case for that board lol. I wonder if it's more for cooling.

[8ight]

Probably for looks and the cooling is a nice byproduct.

I see you listed it has 3 40amp fuses. But I see 3 40 amp fuses on the outside and 3 40amp fuses on the inside.

I'm I correct?

i dont see what you're talking about...i just see the 3 40a

5th and 6th picture from the top, just below the speaker terminals on the inside of the amp you can see the orange fuses. Well in the 6th pic, it's above the speaker terminals.

Yes, that's what I saw. Sure do look like fuses, right?

Opps, I missed that...I copied the specs from somewhere and didn't notice..I'll update the post.

As for fuses on the inside, I seem to recall it having 3 40 amp fuses internally, but I may be thinking of a different amp. I'll check tonight when I'm out at my shop. I'll grab some pictures of the carnage if I have time too.
