Description
This is a finely-crafted homebrew regenerative RF preselector--- based upon circuits that appeared in the
1930's "West Coast Radio Handbook" --- to be used ahead of your classic low-band
superheterodynereceiver,to boost its sensitivity.

It consists of three 1929-vintage balloon-globe tubes: a 224A RF amplifier, a 227 100-KHz crystal calibrator,
& a 280 full-wave rectifier. The unit is completely self contained, has its own built-in power supply, & covers
160-meters, 80-meters, & 40-meters by way of plug-in coils, & is graced with a calibrated "National Radio"
type ACN-1 front panel dial for those bands.

This is NOT "...junk construction," either! Extensive photos available upon specific e-mail request. Thank-you.
