Favorite H H Scott Tube Integrated Amplifier

Is stock power supply capacitance optimal? Any experience out there with adding more capacitance to the power supply in Scott integrateds? An Atlanta tube technician claims that the power supply output may drop off about 10% during demanding passages, and that adding a few more capactors to the power supply can rectify this and help clean up the bass. Could such a modification actually improve the sound, or is it something to be avoided?

Hi Johnny - I'm sorry I can't answer your questions (or that nobody else has), but I thought I would just say hello. I am really continuing to enjoy my 222A.

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
