Hi, I just ran across this forum today and was looking through some of the posts. There seem to be some really intelligent people in here. Anyway, I may be having a problem with my Yorkville XM200 amp. The thing is less than two months old and it seems to be losing volume. Its rated at 200 watts and when I first got it, a volume setting of about 3 was plenty enough when I was practicing with my band. Now I need to turn it up to about 7 just to be heard and if I go any louder I start getting distortion. Could I just be going deaf or can an amp get gradually quieter? Is there anyway to test the output power of the amp? I work as a two way radio tech, so I have a good understanding of electronics and have access to all sorts of test equipment. Any advice is apperciated.
