Audio Research Reference 75 conversion to SE

Sorry to hear you were not able to get the SE update for your amp.

The SE update included the following:

-cryo treated IEC inlet

-better input wiring

-4 high speed diodes

-4 resistor value changes

-hardware to lower the main PCB

-tubes, dampers, badges

Thanks a lot Skucie.

It sounds like a competent engineer could make most of these changes if the values and locations of the components could be ascertained.

I can undertake lowering the main board myself to fit the taller tubes.

Well “fingers crossed” someone on here can fill in the gaps then.

cheers

Have you asked ARC what the kit consisted of, specifically the resistors and diodes?
