Hi all,
I have a question about the use
of mains power conditioners. Put simply, I’d like to understand the problems that they can address, the features one should look for in a conditioner/what constitutes a well engineered conditioner and any recommendations on particular products.
Behind my question lies a problem, namely that I have an audible, constant lower mid band hum emitting from the headphone (but not the speakers) output of my new amp. I suspect it is down to some local condition with my mains, as i had the same precise problem with another restored vintage amp by the same designer. Anyway, I’m not going to start randomly buying equipment until I’ve diagnosed the problem, and the designer has been extremely helpful offered to help me trouble shoot this issue. The amp has been fully tested and there are no obvious faults. I’m largely interested in understanding the general issues around mains power and amplification.
