GEC BC5645

After many months of distractions, I finally got round to starting the BC 5645 today!

It's not in bad condition, although the Bakelite cabinet is going to need a lot of polishing to reduce the visibility of some scratches.

The chassis came out first so that I could give the inside of the cabinet a good clean. Two of the baffle board mounts had broken off; one was in the bottom of the cabinet but unfortunately the other has been lost.


Next to come out was the baffle and speaker, and then, after a good clean and vacuum, I glued the broken mount back in place. A 2BA bolt with the head set in Araldite replaced the missing mount on the other side.

The speaker cloth has seen better days, so this also came off and will be replaced with some new fabric.


The chassis had a light coat of rust in places, but a bit of effort with a brass brush removed most of it.

The only mechanical part of the chassis that will need replacement is the curious paper diffuser for the tuning scale. This is held under tension with spring adjusters. Most strange!


It looks like some restoration work was done on the chassis some time in the past, as several of the infamous Hunts capacitors have been replaced. There are still four or five left and these will have to go, along with the one remaining wax paper capacitor.


More updates will follow soon, so....

Keep listening!
