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.

Re: bush ac31
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.

Re: Bush AC31
Wow! It's a bit like Trigger's broom, but well done for saving something I that I would have definitely scrapped for spares.

Re: Bush AC31
What is the suspension like on the tuning cap ? I would expect the TC to be square with the front of the chassis.

Re: Bush AC31
As Nick says I would have put this job aside for spares. Superb job on the chassis and the cabinet.

Re: Bush AC31
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.
