Default identify this amp/board please...

Found this in a shoebox wit a dew others from over a decade ago. well, possibly '02-03 at the least, but doubt it. No heatsink yet, but ill keep looking. The terminal attachments look like old school usamps, but doesn't match my 99 200x. components mount vertical,too

Looking at the transformer coupled hi-level inputs, single layer board and self modulating power supply, I would guess this is also a JENSEN from 89'-94'.

Does it tell you what size fuse is to be inserted since the fuse is missing?

no, it does not. i was not able to find a pic of a jenson internals in that era that uses the transformers and has vertical mounted components.. the original parts are mospec bd907/bd908outputs, and i have no idea on the power fets. i'm guessing something allong the lines of irfz42's. possibly i could use some spare "good used" ones i have laying around and see what happens. i also have 44n's and 48v's..

edit: only have one 42, so that's out..

Sorry to kick this horse, but I found this searching for something else and I can identify it.

It's an OEM'd amplifier that was used in 'Frontier 70w x 2' which was a brand Sears sold. The Sears model had a 3 pin power PLUG for power. It was also used in a white pyramid amplifier but I forget the model #. That model had the power terminal system on this particular PCB. It was a simple design but was pretty clean. Fuse is 15a and those are NOT the stock parts in the PS.. LOL!

Ok, back to finding what I was searching for.

*EDIT* Found it. Pyramids Legacy division. The LA220 - Legacy LA220

*EDIT 2* Since you're wondering why the end cap is grey, but the frontier was black and the legacy was white: Optimus Amplifier & HERE & HERE - Pyramid also OEM'd radio shacks amplifiers. So while they're all the same, this one you have is probably an optimus.
