[AMRadio] A long shot request

[Rob Atkinson]

Hi, I had one of those once around 20 years ago.  Two things to watch
out for:  The switch knobs Ten Tec used can crack and fall off.
Something about the plastic used to make them, and I recall they
aren't decent knobs with brass inserts, instead they're all plastic.
Secondly, the fixed value disc caps TT used will drift on 160 m.   A
number of fellows with that tuner replace them with HEC RF doorknobs
that are rated for some current at 1000 kc.
