Audio Research Reference 75 conversion to SE


Hi guys,

I just had the disappointing news today that ARC no longer supply the conversion kits. 
Other than lowering the PCB to take the taller KT150 tube, does anyone have the knowledge of other upgrade mods ?

“Heres hoping”

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

 

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.

🤞 

 

 

Ok Skucie I will check clearance to cover.

The KT 150’s are 13 mm taller and dealer told me that they wont fit under the cover without lowering the board.

Runwell, I agree buying an 75 SE would be easier - just not sure what the cost delta would be and I would need to finder a buyer for my 75 

Thanks mekong56 for your really helpful account of your upgrade experience.

Obviously if someone can provide exact details of the upgrades then it would be ideal. If information cannot be found then i will just run the amp with the KT150s which as you say will make a great amp even better and not too far behind the SE.

thanks once again, it is really appreciated. 
regards
