This nice little amp was brought in with the reverb tank missing, apart from that the input jack was a bit hit and miss and the whole thing was in a bit of a mess. I was able to get an appropriate reverb tank from Hotrox, the input jack was a bit harder to source […]

Quad power amp in for repair and service, there was a constant background hum, the main filter caps were well in spec so I moved on to the amp modules where I found several caps way off value and a couple were open circuit. I’ve had to order a couple of them so have put
Little Dot valve preamp and Sony Electrostatic speakers in for repair, lots of humming and popping. The speakers checked out fine, part of the problem was the poor quality of the leads being used, but mainly it was being caused by the cheap and nasty phono sockets used for input and output on the preamp,

What a classy amp, made in Sweden by EBS and a few years old now. It was suffering from an annoying hum, even with no instrument plugged in, I traced this to poor earthing on the preamp panel which relies on a good contact between the chassis and the metal bodies of the potentiometers, I

This is a very good quality CD player produced between 1993 and 1995, it’s a very well put together item and weighs more than you might expect due to the heavy gauge of metal used for the chassis and casing. It came to me because it wouldn’t read a disc, this was due to low
Next up, an old Sanyo radio cassette in need of a refurb, all was going well until I found a tooth missing on one of the idler gears, unfortunately not available as a spare part any more so if I want to keep this old thing going I’m going to have to replace the missing
I’ve had this linear drive turntable sitting in the corner of my workshop for several years, it was given to me with a few other items by a customer who no longer wanted it. So eventually I got round to looking at it, first thing I noticed was the original transit material was still attached
