Two Jamo MPA-101 amps not working
I can almost guarantee that you'll find bad electrolytic caps on the power supply board to be the cause of the problem. I've seen several of these with the same problem. The protect circuit stays latched due to excessive ripple.
Jamo MPA-101 2 channel amp quit working
Check the small electrolytics on the power supply board for high ESR, Very common problem on these amps. Protect circuit stays latched due to high ripple from PS.
My jamo d115 speaker tweeter distorts or rattels when any serious bass kicks in, how do you stop this?w
Possible this is a distortion from the Amplifier if the speakers are not damaged. however it is important to switch the speakers to confirm if the fault is relative to the particular channel in which case the amplifier is faulty. If not the speaker can be the culprit. All what is needed is to reduce the BASS level a bit lower when the volume is increased so as to allow the cross over to work. Also if teh cross- over network is faulty within the speaker the bass can vibrate on the tweeter.
