[SADXA] SX-111 trimmer cap needed

[Jim Wysocki]

Here's an off-topic query for you.

My brother is restoring an old Hallicrafters SX-111 receiver. Its been 
kept in a damp basement for many decades and corrosion has taken a heavy 
toll.  He's been able to rejuvenate most of its moving parts, clean out 
the rust from the chassis and touch it up, and sand down and repaint the 
cabinet.   To finish the job he's in need of an antenna trimmer 
capacitor. The original trimmer is so corroded that its rotator shaft 
broke off, along with one of the rotor plates. It's a small 4-50 pf unit 
that has 7 stator plates. He didn't mention it but as I recall this 
trimmer had a 1/4" shaft on it.  It sticks out of the extreme right side 
of the front panel, just below the slide rule dial.  He'll be able to 
reuse its original knob once he finds the appropriate part.

Does anybody have something suitable in their boat anchor junk box that 
can be used as a replacement?

Thanks and 73,  Jim  W9FI
