I actually own 2 of these amps, both with the newer C-styled toroidal transformers. One of these I replaced all 28 output transistors to the newer designation, better signal cable and output speaker cable. I believe the audio is cleaner, slightly tighter bass and mids. These amps have powered my 4 BOSE 901 speakers for years. Maybe it is time to upgrade.
