Audio Research Reference 75 conversion to SE

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?

Hi guys and thanks for your support with this.

I thought maybe best to request the UK dealer to go back and ask the question on my behalf as they have an established relationship with ARC and more likely to get the required help.

🤞 

FWIW  I don't believe it's 'absolutely necessary' to lower the main PCB.  I think the KT150s do fit, but barely. 

It's been a few years so my memory may be failing me.

Why don't you just sell REF 75 and buy new REF 75 SE? It is easy way to go.
