Hi Folks,

I have purchased an Abassador 551 which I am going to attempt to restore.

As I am not very experienced in radio repair, I would appreciate any help and advice

as to the correct proceedure to go about replacing parts that are suspect, and also advice on a source of radio bits and pieces in the UK

On looking at the underside of the chassis I've noticed that all the old wax

condensers/cpacitors are in bad shape and need replacing, there are also a couple

of 22k wire-wound resistors that seem to have overheated. The rest of the under

chassis is quite clean and tidy.

I have downloaded and printed out the schematic and parts list.

Any help/advice will be very much appreciated.

Ray Bancroft.
