Us amps.....But which one is it?

[foreman 10+ year member]

Ok, guys, a couple of us stumbled onto this, i'm assuming older US amps all black amp with the logo etched....Now, on the left side of the amp, it has the gain, US amps name, rca's and a 3 knob vari-loud feature.

The right side has the power and speaker terminals and power/prot. led's.

Amp is normal hight and width, but approx. 20" long.....No markings on the board either(plexi bottom) so i'm stumped.I'm betting on it being an older usa-200, but thats my guess.Anyone else before i test it????????

the older us amps iirc with the smaller model #'s didnt have any knobs my guess is a usa 1000 or 2000

take a pic of the insides. i have the usamps 150, 200 and have seen a few other models, i think i can tell them apart by now.

Pics coming now.Also, no way its a 1000 or higher, amp is under 24".........

looks like a 200 to me..

heres a pic of mine, the 150 has less caps and looks smaller, the models higher up have more stuff, thats how u can usually tell, funny eh?

but i don't have that variloud thingy like u do, mine might be older. mine does have USA-200 printed on it though.

Korndog, how long is your 200? I think its a 200 as well, but i'll actually have to test it i think........I'm amazed though, NO markings whatsoever on the amp, aside from the name, no model number anywhere, board, side, nothing......

16" long. i remember seeing some of the promo 200s (purple funky colored ones) w/o anything on them either.

hey, if it turns out to be a 200, could u test it at 1ohm mono? i'd like to see what it puts out and if its stable.

Hmmmmmm. Might be an older 300 or 400, cause its roughly 19-20 inches........I wont play with it at 1 ohm, just 2, its not an hc, at least i don't think it is //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

19? r u measureing just the top heatsink part (like i am) or including the mounting and terminals, cuz with the terminals i get roughly 19. everything on the board is in the same quantity and order, even same color. steping down or up from the 200, they don't use the same quantity or same things, for example on the 300, the caps are fatter and flatter. on the 150, there are about half the amount of caps.

models with the vari loud feature use higher models numbers than the old but then again thats a thin chasis lol like my old 600 (newer chasis than that though) looked like that but it had a wider heatsink (didnt think it was 20" long either though i know the 400's were longer than that (not talking vlx) but they never had anything else to them no x over or anything
