Offering a unique opportunity to purchase a near mint, later vintage
Collins 30L1 winged emblem amplifier(#101XX)w/four 811A's. The
internal circuity has an upgraded filter capacitor/bleeder board with
6 new replacement 180mFd 450VDC capacitors and new bleeders to
eliminate an all too frequent component(s) failure in the high voltage
section. New GE rectifier diodes have been installed. In addition, the
board contains an integrated 12VDC power supply and intermediate relay
to ensure solid state exciter antenna changeover compatibility.
Parasitic chokes have been replaced with 2 pair of parallel 100ohm 3
watters. The amp, w/100w of drive (wired for 110VAC), easily makes
800w output on a Bird wattmeter/dummy load with 2000VDC on the plates.
There are no issues of discoloration, bangs, dents, or dings and the
amplifier is otherwise absolutely original. The tubes are bright with
no discoloration. Prefer pickup but will reluctantly ship via the UPS
Store. $875+ shipping Ron W2CQM/3
