These are prototypes! They work and work great. There's a few "goofs" on the silk screen, but docs are included!

This old work horse is starting to feel the effects of 30 plus years on its internal power supply. This upgrade replaces the old worn out supply with a new one.

You get 3 A diodes with a 1000V dc rating. The capacitors have been increased from 150 Mfd to 220 Mfd @ 450V dc. The meter shunt resistors is now mounted on the the pcb and is rated at 5 watts. The voltage divider used to read plate volatge in now on the pcb, too. Instead of just three resistors in the divider, there's now 10! All resistors are flameproof and exceed original power ratings!

The pcb is .093 thick! It's double sided with plated through holes. There's a solder maske applied on both sides and a silk screen applied to the part side.

PCB being tested

Note: This is NOT a project for the Novice builder!! The voltages contained inside the amplifier and on the pcb are deadly!
