Miller Model 595 High Fidelity AM tuner crystal radio

The Miller 595 High Fidelity Tuner is actually a dual tuned circuit crystal radio praised as the most selective crystal radio ever made. This is made possible by the dual tuned bandpass circuit and the vernier gear reduction tuning drive mechanism. This set is in good working condition, and the cosmetic condition is good or better with some minor scratches on toop and fading on the faceplate. Tested and working and I can pick up 10 or so stations here with a 15 foot indoor wire antenna. The original output cord can plug into an amplifier or you can hook up high impedance headphones. $155
