For sale, a later model Collins 30L1 WINGED EMBLEM  
amplifier(serial #101XX)w/four full output USA 811A's. Has a 
replacement filter capacitor/bleeder board installed   with improved  
voltage regulation capacity 180mFd 450VDC capacitors along with 
complementing replacement  diodes and bleeders. The amplifier also 
contains an integrated  intermediate low voltage relay circuit  to 
ensure solid state exciter antenna changeover compatibility. Parasitic 
chokes have been upgraded w/parallel pairs of 100ohm 3 watt MOF 
resistors. The amp, w/100w of drive (wired for 110VAC and 2000VDC 
plate voltage)makes a verified 800w output as measured on a Bird 
Wattmeter/dummy load. There are no issues of discoloration, bangs, 
dents, extraneous holes or dings.Other than the capacitor board 
circuit change, the amplifier  is absolutely original with N connector 
and original "mil spec" porcelain low loss RCA jack inputs. Prefer
