W7RY Heathkit SB-220 HL-2200 Diode and Metering Board Rectifier Board

Description

Another W7RY Circuit Board for the Heathkit SB-220!
A rectifier and metering resistor circuit board for the Heathkit SB-220, SB-221 and the Heathkit HL-2200 linear amplifier.
The board also has several components to help in protecting the meters and other parts in case of a shorted tube event, or arc flash inside of a tube.
The board DOES NOT include a zener diode for bias.
You use your stock zener diode that is already in the amplifier
or the W7RY QSK board which is available in my other auctions.
It uses 1N5408 diodes which are 1000PIV @ 3Amp for high voltage rectifiers.
The 14ea 1 Megohm high voltage metering resistors should be 1% for best HV meter accuracy.
As you can see from the pictures, I provided a location for C7, the .001 6KV capacitor that normally is "hanging" between the HV feed-through and ground.
