Hello,
I have circa 2002 Fender Hotrod Deluxe 112 tube amp that no longer has any low end bass response. The amp is shrill, only outputting midrange frequencies and higher. I inspected the main board for blown components and leaky/bulging capacitors -- there are none. I also replaced the tubes and still have the same issue. I understand component level repair and have a schematic. Can someone give me some a push on what to check?
Thanks,
