Offering a near mint, single 3-500Z,  Ameritron AL80 compact, table top
linear amplifier for dedicated  575W OUTPUT  (90 Watts drive) 6m 
operation.  The unit has been completely rebuilt around a brand new HD
plate transformer (no voltage sag) and a  full wave bridge rectifier
replacing the doubler circuit. The diodes,  filter capacitors( Nichicon
330mFd@ 450VDC)  and  bleeders are all placed on a single board,  Broad
banded pi-net components allow for 1mHz excursions without retuning when
chasing DX. Provisions are made for filament  voltage adjustments i.e., 
preventing fatal  filament overvoltage using a nichrome wire series
installed strip in the transformer scrondary. Unit has been designed for 
 fully compatible use with  the new solid state exciters with a 12VDC
antenna changeover relay. A  front panel fully adjustable exciter  input 
"T" match and a mica blocking capacitor assure absolute minimum  SWR
resulting in full drive.  Unit appears stock in all aspects except that
the bandswitch has been replaced with the "T" match on the front panel.
The amplifier is wired for 115VAC operation.  Asking $625* without a
tube. $725* with a full output Eimac 3-500Z.  Ron W2CQM/3
