Hello guys.
I'm new to the forum.
I have made minor repairs on my equipments like replacing capacitors and improving some soldering and although I have an engineer training my career has been in configurations of telecommunication equipment ... so the few school knowledge of electronics are almost completely forgotten
However, as all of us here, music lovers, like to take and enjoy the best sound that our equipment can deliver.
As such, I have already made substitutions of poor quality potentiometers for the multi-turn type, but I have some doubts that I'm sure you can clarify as well as others.
My actual gear are a almost 20 years old Pimare Pre-30 and Primare A30.2, love them, by the-way
For power (A30.2) as the Service Manual is explicit the doubt is in the procedure ... should I short-circuit the inputs? I.e. get the 20mV with the xlr pins 2 and 3 shunted? The service manual called it idle current adjustment, what about dc-offset?
Now for Pre-30, that's a hard-one for me... I really don't know where or what should be measured by adjusting that multi-turn's.
Please note, have attached both service manual. Hop that also helps everyone o cares.
Thank's great forum
