Restoring Fisher 500-C
#1

I have been working on restoring a Fisher 500-C model lately. This one is among the earliest ones released, SN 10000-19999 and as such uses 6GK5 RF Amp and 6AQ8/ECC85 Mixer Osc tubes instead of having the Nuvistor front end of the later models. It was missing the dial lamp replacement label. The FCC compliance label and the GOLDEN SYNCHRODE labels were damaged and hard to read. The unit had a lot of rust on the output transformers and cleaning was a real must for this unit. Some of the cleaning wound up removing some lettering on the chassis. I created new lettering using Testor's decal kit and my ink-jet printer. The dial lamp, FCC label and GOLDEN SYNCHRODE labels were reproduced on my laser printer. Gold foil paper for the front end label was found at a hobby shop. Transformer end bells were removed, cleaned and repainted. The chassis cleaning required lots of time and effort.

I just finished cleaning the front glass and meter faces and installed rebuilt festoon lamps for the dial. I am now working on adding Dave Gillespies EFB circuitry to the unit and will also add the Fisher Forum of AudioKarma.org IBAM modification that allows individual output tube bias setting for best life and lowest distortion.

This will be a great performer when finished. See pictures at:
