Of all the tuners i have worked on, I think this one takes the prize for beauty
and good engineering. While waiting for capacitors i decided to clean and lube
bushings and contacts.
The round contacts on the channel strips were easily pollished using a pencil eraser. Notice the copper plate used for adjusting the oscillator,This simple solid design sure beats tuning slugs in card board tubing.
Could there be a nicer tuner work on?
Drum assy, The shaft sleaved with brass bushings.
Also polished the stationary contacts and applied tuner lube.
Round 2 may be a little tougher
Supprisingly the broken wire wound resistor is still hanging by a thread and has continuity (R181 220 ohm 3 watt) couples the cathode of the horizontal output tube to ground. Careful scrutiny of the output circuit will done as both resistor and tube have been running a little hot.
