Peter,
Thank you.
Just for possible future. Do you also service and calibrate R2R decks or could give a referral ? I might get Otari deck later, not likely Studer.
But for now I only have my VAC Avatar's SE volume control knob making scratching noises. I don't know if it is a wear or just dirt, but I am not going to ship it to VAC for that or even take it to your facilities. It's minor at the moment.
