slybu Posted May 22 Report Share Posted May 22 My bro found this amp in a house he bought, not tested it yet to see if it works but will get round to that this weekend. cleaned it up since it was very dirty. are these amps any good or they just junk that doesnt even make rated power?

crispy_chick3n Posted May 23 Report Share Posted May 23 i remember these... good for something small... single 10/12 maybe a pair of 8s. i wouldnt expect to knock the block down with it, but if it works it should put a couple hundred watts out Quote This page is crispy_chick3n approved. © crispy_chick3n inc Link to comment Share on other sites More sharing options...

slybu Posted May 25 Author Report Share Posted May 25 turns out there is a fault with this amp. had a speaker connected to it and as soon as amp is powered on the speaker cone is pulled down and stays down unless amp is powered off. keep amp powered on too long and speaker smokes. good thing im testing it with used old speakers from junk yard and not my main sub. not sure what this fault is or how it can be fixed. fuse doesnt pop on the amp either. and i used a 10amp fuse to be on the safe side.

slybu Posted May 25 Author Report Share Posted May 25 I suspect this amp is putting out dc voltage on the speaker outputs. Need to check what it could be. I suspect transistor maybe Quote Link to comment Share on other sites More sharing options...
crispy_chick3n Posted May 25 Report Share Posted May 25 youll spend more time and effort than its worth fixing that amp. sometimes thats just the way it goes. when you tested it were the RCAs plugged in?

slybu Posted May 30 Author Report Share Posted May 30 no, i didnt plug in the rca's, just had the + and - connected to a car battery and one 4ohm old car speaker connected up. i like dabbling with electronics in my spare time so may give it a go at some point to see if it can be fixed. the gain knob being set at max was probably a good indicator of how the previous owner ran this amp.
