This video sums it up, apologies to those with sensitive hearing:

Anyway, enough of the frivolities, let’s see what’s wrong and try to fix it.

On initial examination, everything seems to be there, no damage to the shell. Four AA batteries inserted and I do hear some feedback from the mic.

There are some volume controls that control the tape sound versus mic sound, there is also a speech on and off switch along with a balance control, these seem to work intermittently and I suspect they might just need contacts cleaning.

The tape seems to sort of work but the play button does not stay on, the recorded sound is slow. Echo and balance buttons also seem to work but again probably need contacts cleaning. I suspect the belt of the cassette needs replacing and the tape heads will need cleaning.

Good news is that for once there is no corrosion on the battery contacts.

I will now have to open the unit up to observe closer.

Once inside there are a couple of issues that show straight away. The two drive belts are very loose and will require replacing, luckily I have a bag full of these that should do the job. There is also a wire detached that controls the motor, this will need re attaching at both ends.

I’ve reattached the wire and replaced the two drive belts. I’ve checked the board and found what looks like a burnt capacitor, but checks confirm there is no issue. Looks like the component has a small burn on it as a result of an earlier soldering attempt, probably during manufacture.

The main issue is that the play button will not engage. I spent a good 30 minutes scratching my head here until I spent some time clicking the buttons that worked and the stop button. There is a catch on the rear of the tape head that should click into the sliding stop mechanism when depressed, this was not quite making the full range of travel. A pair of pinch nose pliers and a slight adjustment of about 1mm ensured we were now working. I was worried I might over stress this catch, however it was made of steel and I had nothing to worry about. See the video below:

There was nothing wrong with any of the volume controls or switches, so I used some contact cleaning spray and vigorously operated them for a minute or so each. This worked just fine.

I then reassembled the unit, put in some batteries and hey presto, good loud clean sound. I put a tape in and it played just fine, probably better than some of the Walkmans I’ve fixed lately.

I’ve put a little video up above of me singing into it, I haven’t played a tape due to copyright issues that might occur. I’ve sent the video to the family of me singing with a tape and they are suitably bemused, the unit now sits in our garden pub awaiting more customers, once I get a few Karaoke tapes to use.

The only thing I’m going to do is replace the foam mic cover, I’ve managed to source one and that should be here shortly. I’ve also found some cheap old Karaoke tapes that I’ll store in the pub for the families entertainment.

I’ve really enjoyed this little project, and once again I’ve salvaged another item that was broken from the 90s and saved it from landfill. It lives on.

Good job 👍
