[Amps] SELL: 12:1 Vernier

[w2cqm at juno.com]

Offering a pair of 12:1 verniers. Super  high quality w/zero backlash.
Accepts a 1/4" shaft on the  split collar compression fit input on the
vernier.  Primary end will accept a 1/4"  set screw (spinner)  knob.  
Vernier assembly can be front panel mounted and will accept  an  8x32
threaded bolt.   There is no continuity between the input and output
shaft so it doubles as a shaft insulator. One unit  is available with an
optional chassis mounting bracket.  $13 each or $25 for the pair +
shipping. Ron W2CQM/3
