 AM-494 VHF Linear Amplifier - Make your voice heard on  2 meters.
 This is a surplus unit that originally covered 150 to 160 MHz.
 It will probably do fine on the 2m ham band as-is, with no circuit changes. 
Uses a pair of 4X150
 tubes (included) and  a silver, strip-line tuned tank resonator circuit.
 Has tuned input also.

 It is basically the same kind of circuit hams have  used for decades to get 
1000 Watts input on 2m.
Has internal power supply of 1100 V DC  for max input, plus filaments. Not 
sure if the
original circuit used fixed bias or not.
Unit has metering TEST, PLATE CURRENT, PLATE VOLTAGE
There is also a manual for the unit.
 Neat design has two VELVET VENIRE DIALS for the tuning up.
 This unit is in excellent condition inside and out.
The bottom section has the power supply and the entire rack as covers to
 protect the units inside
Power supply is set for 120 VAC but can be set up for 240 VAC.

 Only problem is it is heavy and needs to be picked up at my QTH in Delaware

Asking $200.00
