Hafler DH200 sounds scratchy /static


My DH200 has been sitting for years and now sounds pretty weak and scratchy. 1980's vintage, I hear some people talk about breaking in an amp with a variac if it's been sitting a long time...is it necessary? I've checked all fuses.

The pre-amp has been sitting also, it's a Classe' CP-50 purchased in 1999' with regular and balanced outputs.
