Amplifiers

A Cambridge Audio A5 amplifier with a dead output channel required repairing. This amp looks very similar to the A500 amplifier, so lets take a look at repairing it.

This old AU-317 Sansui amplifier was putting strange clicking sounds on the speakers when the volume was turned up. This takes a look at the fault and how I repaired it.

A faulty Rotel A14MKII needed to be repaired as it was wired up for a 110v mains supply and was connected to a 230v supply. That’s never a good idea as all the transformer output voltages will be double!

A nice looking compact Nikko TRM-50 vintage amplifier came in for repair. This takes a look at it.

An old Kenwood KA-550D amplifier with sound problems came in to be repaired.

A Cyrus 2 amplifier and PSX power supply needed repairing. This is a quick look at it.

This old Quad 34 preamp was picking up computer noises when connected to a PC based audio streamer.

This old Hitachi HA-5300 required repairing as it had distortion on one channel.
