It might just be dirty contacts. My Scott 222c did that initially because some tubes had worked loose during shipping. My suggestion is that you first make sure it is not some other component in the chain causing the crackling sound by switching components. If the sound persists, clean all connections thoroughly - I prefer to use Cramolin products. If it still persists, clean the potentiometers. Make sure the tube sockets are clean and tight. If you know how to work safely with the unit on, try tapping the tubes gently - if one makes a particularly loud noise, you may have a microphonic tube. If a tube has a bluish glow, it could be gassy. If you have access to a tube checker, check the tubes one by one, making sure that you put each back in its respective socket (if you have two matched pairs and not a matched quartet on the power tubes, changing the order could affect the sound). If all these measures fail, I would refer you Benny at Modular Electronics in Roswell, Georgia. He's the tube tech many of the high-end dealers in Atlanta use, so he comes highly recommended.
Favorite H H Scott Tube Integrated Amplifier
I just purchased an H H Scott 222c integrated amplifier on these very pages. Wow, it is hard to believe that this thing was built in the early 1960's. Using it to drive Rogers LS 3/5a's, the palpability and realism on vocals and lead instruments can be startling at times. It totally blew away some highly regarded solid state gear I was using previously.
H H Scott made other integrated amps with different features, transformers, output tubes and power ratings. I am interested in hearing about other people's experiences with this and other models. I think that this gear is very under-rated, and can stand up favorably to many more expensive modern efforts. Do others agree?
