[Boatanchors] FS: Multi Elmac AF67 Transmitter

FOR SALE: Multi Elmac AF67 Transmitter
from an estate. Appears complete, but sold as-is, untested.

This AM-CW Transmitter as ten tubes and uses VFO or Crystals to cover SEVEN (7) bands
Some have also modified these rigs for DSB operation.

The MULTI-ELMAC AF-67 "Trans-Citer" is a ten-tube variable frequency or crystal controlled 
seven band transmitter or exciter. All circuits are simultaneously switched to the desired band 
by a single bandswitch lever.  Designed as a complete transmitter for mobile or fixed 
installations, or an exciter to drive a higher power transmitter. When used as an exciter the 
500 ohm tap on modulation transformer can be used to drive the higher power modulators.

DIMENSIONS. The maximum external dimensions of the AF-67 Trans-citer, excluding 
projections of control knobs, is 11 1/4 inches wide, 7 inches high, and 8 1/2 inches deep 
behind panel. Approximate weight is 18 pounds.

CIRCUIT DESCRIPTION. The AF-67 Trans-citer employs a variable frequency oscillator with 
output on wither 1.75 to 2.0 Mc. or 3.5 to 4.0 Mc. In addition to the V.F.O. feature, two crystal 
positions are included for operation on two spot frequencies. Any crystal that will work 
straight through, double of quadruple to the desired frequency may be used. The oscillator 
circuit employs a voltage regulator tube to maintain the plate voltage at a constant level.
The multiplier stages are broad tuned with a front panel control for peaking the final grid, 
insuring best performance on all bands. The audio circuit is designed to use either a carbon 
microphone or a low output microphone such as a crystal or dynamic. A slide switch on the 
rear apron on the AF-67 Trans-citer sets up the circuit for use with either type of microphone. 
A reactance tube modulator is incorporated in the variable frequency oscillator circuit for 
narrow-band-frequency-modulation. The variable frequency oscillator dial scale is directly 
calibrated in megacycles for each of the amateur bands. 

Looks fairly average. No power supply is included.  E-mail me for pictures if desired.

Available for $75.00 plus shipping.
