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?

I tweaked my 222c, and now it sounds even better. The tweaks were simple and reversible. First, I replaced my old 7189a power tubes with matched new tubes. I couldn't find a matched quartet, but I had a number of tubes on hand so I was able to get matched pairs on each channel. Next, I followed my tech's advice who measured the power supply sagging on demanding passages, and added two extra capacitors to the stiffen power supply. (If I didn't like the result, he offered to remove them free.) No alterations were made in the signal path. The result? Background instruments and vocals are now much more defined and distinct. The striking you-are-there quality on lead vocals and instruments now extends to the background as well. The sometimes wooly bass that I took to be a feature of living with a low-powered tube amp has tightened up considerably. My conclusions? It is definitely worth springing for good matched power tubes. If you have a good tech and your amp sounds good but suffers in the bass, consider whether the diagnosis might be a power supply inadequacy. This is the second amp I have owned for which adding capacitance to the power supply made a noticeable improvement. Personally, I still would not make any changes in the signal path unless absolutely necessary. Any other experiences out there with these kinds of tweaks?
What speakers go well with your model integrated amplifier? My Rogers LS 3/5a's really seem to like my model 222c, but I wonder what other speaker-H H scott integrated amp combinations can be recommended.
A Spendor BC-1 / Scott 222c combo was auditioned. The Spendor's were very musical and listenable, but didn't seem to mesh with the 222c as well as the LS 3/5a's on most material, at least not to my ears. Although vocal clarity was excellent, the Spendors were a bit harder on top, more extended but loose on the bottom, and listening position was much more critical. Perhaps a more recent model Spendor would match better. I still wonder what other speaker-H H scott integrated amp combinations others have tried that can be recommended
Hello, I thought I would wake up this thread with a question (and boy do I sound like a total newby up there in those old posts!). Alas, my 222A is starting crackle and pop somewhat frueqently. My problem is, where do I go/send it to get it checked out? I read enough warnings about how various replacements could ruin what I like most about this amps sound, so now I am wary. I live in Philly, but I could ship it anywhere. I tried writing www.hotglassaudio.com and http://www.nosvalves.com/, but the former's mailbox was full and the latter seems quite busy. In addition, I know nothing about either one (just Google). I have about zero electronics knowledge, but is there anything I could check on my own? Could it just be tubes?
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.
