[1000mp] HEATHKIT SB-200 vs YAESU MUSEN FL-2100B

Sat, 16 Feb 2002 01:08:08 -0500

Hello All....

I have both the SB 200 and SB 220 here, and they both work well with my Mark 
V...Do not exceed about 500 mils grid drive on the SB 200, and load the 
linear for maximum output at that drive level....You should be able to 
achieve from 700 to 800 watts, on a stiff 240 volt line...I used a variac 
for years to set the high voltage level to about 2400 volts, to assure full 
output....The 572B is robust, and although it runs hot, it can take it 
well...I still have 3 spare pairs of Cetrons which I never 
needed....Although some folks have changed the parasitic suppressors for 
lower Q types, I never had any instability or arcing within mine...and it is 
stock...I can not say the same for the SB 220 with a pair of high mu Chinese 
3-500ZG tubes...I will publish an article about my experience with these 
higher gain tubes, in the original circuit...and what it takes to calm it 
down....Go for the SB 200, either with or without ALC, and have fun....
