I have a Cayin HA-2 headphone amp which worked for several months, until the audio sound became almost minimal. You can still hear music, but just barely. This may be a problem with the volume control. Does anybody know a reputable repair company with experience to handle this kind of problem?
Steve may be able to fit my repair in his schedule but maybe not. If for some reason, he is not available, any other ideas who has the expertise to do the repair?
As to the question about tubes, it is not a tube issue, as I tried more than one pair without any improvement.
I would google a repair facility close to where you live. Try it on yelp or some other site that rates such things. Or google high end tube repair shops and hopefully something close will come up.
This has been done already on other threads and there are some very qualified folk out there that can diagnose and do the work.
