Aster Radio 702 12

Below find attached pictures of the Aster 702 12 that was on my 1946 6C 2500 SS Pininfarina Cabriolet. Obviously the radio is in need of restoration and will check with the DePoi brothers in Turin. I am not very optimistic as there is no schematic in the Radiomuseum site and the radio appears to have been cannibalized in the past.

ASTER Replacement Valves

It is difficult to say without knowing what valve needs replacing. Some of the valves of the period 1945 - 1955 evolved through several iterations. They are generally very reliable and are far more long lasting than many of the other components in these radios.

All of the seven valves in my radio are still working to specification, but in my research I have found direct replacements for 6 of them are still available. Several of them have been superceded with higher capacity versions and require 9 pin base jacks to be fitted to replace the original 8 pin ones.

A good radio valve electrician can restore/rebuild the electronics in most of these radios. The mechanical parts, dial and knobs are more difficult to repair or replace.

Vintage Radio has lots of knobs. Some of the older tubes have been updated with transistors inside of them so they look original. The Russians were for a while if they are still doing it, making batch runs of tubes. When I was a ham oper. it was getting harder to find a matched set of drivers for the final outputs to some of the "glow in the radios'". Matched sets went for a premium.
There are radio collectors now that restore radios to like new spec. You would be amazed at how beautiful they sound and look.
Changing base pins is easy and who would know unless you opened the cover. It would just have to know what pin goes to which plate. I was wondering how hard it is to get good electolytic capacitors or vibrators?

Aster and Condor repairs

Just to add some further information to this thread, I found a specialist at this year's Technoclassica show in Essen who (to my relatively untrained eyes) showed some nice restorations of old radios such as the Aster models shown in earlier posts, above. None of them were shown working and photos were not permitted to be taken at his stand, so I took a business card which is shown below. His name is Dott. Lino Carlini and I believe he is based in the Milan area. Maybe some of the Italian BB'ers know of him already and can comment further?

Alex.

EDIT: More information here.
