Armstrong 625 restoration
The tuning indicator cum signal strength meter has stopped working with the needle stopped at the centre. Any ideas how to get it going again would be appreciated.
Also most of the radio tuning presets have stopped working. I've tried squirting contact cleaner on them but no joy. Any ideas? |

Re: Armstrong 625 restoration
That smacks of a power supply fault but I don't know enough about this tuner to be sure. The diagram on Jim Lesurf's web site suggests that the 45v line is the one to look at as it supplies both the pre-sets and the tuning meter.

Re: Armstrong 625 restoration
In my experience 50% of the meters on this line of Armstrong units are faulty. Could be something else of course.

Re: Armstrong 625 restoration
Does the manual tuning still work ?
Even when the units were new the meters did fail quite often not terrible but enough to be annoying I use to retail these at the time |
