Rectifier and Metering Resistor Circuit Board for the Heathkit SB-220/221 & HL-2200

The board is fully wired and also includes several components to protect the meters and other parts in case of an arc inside or short circuit of a tube.

This card has 8 - 1N5408 diodes that replace the original zener diode.

The high voltage rectifier diodes are 1N5408 supporting 1000PIV @ 3Amp for each, i.e. 6000 V / 3 Amp for each branch.

As you can see on the pictures, a place is provided for C7, the 1nF/6KV capacitor which is normally "suspended" between the HV feed through and the ground. It features a new meter shunt resistors.

The board fits in the same place as the original Heathkit board and the wire hole locations are the same and in the same relative positions so that the amplifier wires are compatible with the new board.

This sale is for a fully equipped HIGH QUALITY board as shown, (silk-screened double-sided epoxy PCB with plated holes etc...).

The parts list, schematics, and installation notes will be provided by download, in PDF format. This is not a kit. This is a fully assembled circuit board, ready to use.

Attention! Concerning the module for the HL-2200, some components are different, please specify the model when ordering.

Note: I can also make:

- HV doubler rectifiers 3, 6, 10 Amps (up to 20 000V per branch)

- HV Bridge rectifiers 3, 6, 10 Amps (up to 10 000V per branch)

 If you have any questions, please send me an email.
