A Marshall guitar amp came in recently, the only sound it would make was an awful screeching, the fault was traced to a failing preamp ic, luckily a common and easily available component. All up together and sounding good now.

A Hitachi HiFi I had in a couple of months ago, it meant a lot to the owner as he and his wife had bought it many years ago, but it now needed a lot of attention. First problem was it only worked on one channel, this was down to the volume control, it needed stripping and cleaning but also one of the wipers had come loose from the body of the control and had to be glued back into place. I started here because if the control was not repairable it would have been curtains for the whole unit...fortunately it all went back together and worked very well.
The tape decks needed new belts and a good clean of the tape paths, the take up clutch on one of them had blown apart but luckily all the bits were still inside the unit, so it was just a matter of rebuilding it.
Then I moved on to the turntable, it was very hard to move which was being caused by congealed grease inside the spindle, that was stripped cleaned and regreased, a new belt and stylus had that working well and all that was left was to clean all the controls and give it a good test.
Now back where it belongs with it's grateful owner.

A kenwood HiFi brought in recently for repair, there was just a loud hum from the amp, so my fault finding started there, not easy to get into but it was full of dry joints, the speaker relay had tarnished contacts and the glue holding the main capacitors in place was probably conductive and had to be removed, none of that cured the hum though, I didn't think it would but it was stuff that needed to be done. The cause of the hum was the phono preamp ic that was busy cooking itself in the corner of the panel, I replaced that and the two fusible resistors in it's + and - supplies, the hum was now gone. On to the tape deck, new belts, full strip, clean and lubricate, then the turntable needed a belt and a stylus and a quick service of the gummed up auto return mechanism, the cd mech was given a good clean and service. What a job, it's taken a couple of weeks to finish, working on it in between other jobs, good to get it going though, it hadn't been used for years but maybe now it will get the use it deserves.

That's the 1958 Roberts Radio completed. The circuit board had snapped in half and had to be repaired and bridged, one of the output transistors was faulty so I replaced the pair of them and a Thermistor had burned up, that was replaced with an original part all the way from Malta. The last thing to do was set the quiescent current, box it up and send it home.

This was once a system used to distribute the rf output from a sky box around multiple rooms, over the years it had been added to a couple of times and now it was just an unreliable mess. The main 8 way amp was doing an ok job but then there was a Global Tv Link amp that had been added and was now destroying the signal quality to the rooms it supplied, then there was the Vision distribution amp that was just hanging there and over amplifying the signal. The Sky box was long gone and all that was needed now was a decent distribution amp to even out the signal to each room, as it stood there were four levels of signal being sent round the building, one low level signal from the 2 way masthead power supply, an ok signal level from the 8 way amp, no signal from the non working Global Link amp, and an over amplified signal from the vision amp...what a mess! Anyway, before, during and after photos of replacing it all with a good quality amp.

A couple of audio projects to kick off the week, firstly the new output transistors were fitted to the 1950’s Roberts radio, still waiting for the thermistor to arrive so that’s been put to one side. Then on to the Mordaunt Short speaker with the broken connection plate, over the weekend I managed to coat it with epoxy resin which seemed to have hardened nicely and I was able to refit the binding posts and crossover network, also put to one side until I find some time to reassemble and test….busy week of service calls already booked!

A couple of retro systems kindly donated to me (saved from the skip) that I'll be working on over the next few weeks / months. Not high end but not rubbish either, I should be able to turn them into something nice!

On the bench this morning, an old Roberts Radio from 1958, someone had put a 9v battery in place of the correct 6v, although I'm not sure this was the sole cause of it's demise because, judging by the crack in the panel, it looks like it's had some rough handling. Well having repaired the crack I've now found leaky output transistors, Mullard OC72's, I can't remember ever seeing those transistor types before but was able to find some good second hand ones online, then there was a thermistor, part of the base bias circuit that had overheated and fallen apart, I didn't hold much hope for finding one of those, a VA1040, but by some miracle found a supplier in Malta with a few in stock. So I'm just waiting for these parts to arrive before I can carry on.

Well I do find myself in some 'interesting' places! The reception in this building was very poor and a good place to start fault finding was in the cupboard containing the aerial amps, it would either be the amps themselves or the signal coming down from the aerial...wherever that was, and that was where the fun started. The signal was not coming down from the aerial so the search started to see if I could find it. There was a redundant one at the far end of the building which was nothing to do with the problem, I was then told there was another aerial only accessible from a hatch onto the roof, it didn't turn out to be that one either, but while I was up there I spotted another one hiding behind a chimney. It was invisible from ground level and it required a long ladder to reach it but once up there I could see the cover had come off the masthead amplifier and it had filled with water, miraculously it was still working but only putting out half the signal it was receiving from the aerial, well by the time this weak signal had travelled down a long length of cable to the aerial cupboard there was nothing left, a new masthead amp sorted the whole system out and I was very pleased to be back on ground level!

First up this morning is a speaker with a broken speaker connection plate, I tried everywhere to get a replacement but as it’s rather old I didn’t have any luck. So, it was lucky all the broken pieces were present, I was able to piece them back together and tack them in to place with my soldering iron, now I need to find a way to hold it all in place in a more permanent way, I’m thinking some fibre glass resin so will be popping down the car accessory shop later.
It’s a work in progress and will post results in a few days

Finishing touches (stylus and hinges) done to this lovely old Sony and now back with its very happy owner. I have to say it looks and sounds lovely and should go on for a few more decades.
