Left channel not working , and general service

There is no output sound from the Cambridge Audio 640P phono amplifier.

Amplifier powering up, but making very little sounds. The cause may simply be the tubes, or there may be an additional problem. The amp takes 2X ECC83 & 1x EL84.

I have an Audison SRX3 car amplifier that went into safety mode a few times before working again after a few hours. It's now permanently in safety mode after I raised the volume, and won't work. The car's wiring, fuses, speakers and sub are all fine. I suspect it was due to overheating as it was in a tight, unvetilated area in my boot. Is there a chance to have this repaired?

Technics stereo amplifier

I had a carplay installed in my Renault Kadger 2017, but the car has a factory bose amplifier .the amplifier does not power on as it is designed to be powered on from the original head unit . This is because the factory wiring expects a specific signal or power configuration from the original head unit, which aftermarket units do not provide by default. so i understand there is a solution to fix this is by Manual Bypass Using Speaker Wires or if you have a better idea

Please repair the circuit on my car amplifier. It is a Mercedes Logic 7 amp.

I have a Lexus gs450h and the drivers side speakers are making a fuzzing noise and all the speakers go on a lower volume than before even if hits up on full blast , sometimes they will go back to normal for 30 mins and then happen again

The amplifier is playing ok. There is a minor 'fizz' noise when the amplifier is switched on. The meter level seems to indicate that 1 channel is more powerful than the other. Some controls make scratchy noise when adjusted. Overall check to ensure that the amifier is performing as it should.
