Default Bush AC31

This radio was given to me by a friend the tenant had left (see pics) wasn't really worth doing but anyway I did. More pics to follow.

All the valves had to be replaced, the speaker and the usual wax caps. The tenant had taken an interest in the coils for the MW and I had to repair the break, it was like stitching the stitches as the wire was so fine. I had to re string the drive cord and it kept coming off, to begin with I thought it was caused by the funny angle of the pulley on the tuning cap to the tuning spindle but then I could see the cause it was a bit of rust on the pulley, the cord was being lifted by the rust. A little sanding down and a little siver paint cured the problem. My cabinet was rubbed down and varnished as it came from a shed, I didn't want any woodworm problems. It now works well. Oh the transformer was set at 230 volts so all valves were low emmision according to my valve tester. I reformed the HT electrolytic up to it's full voltage rating I have a high voltage power supply for doing that.

Wow! It's a bit like Trigger's broom, but well done for saving something I that I would have definitely scrapped for spares.

What is the suspension like on the tuning cap ? I would expect the TC to be square with the front of the chassis.

As Nick says I would have put this job aside for spares. Superb job on the chassis and the cabinet.

The rubbers on the tuning cap mounts were perished so replaced with grommets. If I remember improved movement didn't rock so much but the mount of tuning cap is like that I think. If I remember another Bush model had a similar mounted angle.
