bracurrie Posted November 7, 2011 Share Posted November 7, 2011 My backup system that I love to toy with is a refurbished HH Scott 222C integrated amp connected to Heresy 1s. The results are very pleasing, but I thought the upper high end was missing. It could be the speakers, so I borrowed a pair of Yamaha NS 30T speakers that I have heard elsewhere and are purported to be very accurate from mid bass through the upper high end. Turns out that while the Heresys may be showing their age a little bit, its the amp that seems to be most of the problem. According to some, HIFI style of the era when the 222C was built rolled off the highs. Anybody out there have any suggestions? Thanks!

Guest " " Posted November 7, 2011 Share Posted November 7, 2011 http://www.mcmlv.org/Archive/HiFi/Scott222C.pdf your unit was built to handle 20khz. The treble circut has a 15db boost/cut. Is that control working correctly? Whats the history of the tubes? May be just a general indicator of needing service. Quote Link to comment Share on other sites More sharing options...
bracurrie Posted November 8, 2011 Author Share Posted November 8, 2011 The unit has been refurbished with new capacitors and some other resistors. The tubes were evaluated and no recommendation to replace was indicated. The treble cut switch is working properly. Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted November 8, 2011 Share Posted November 8, 2011 Is it possible you're used to something that just has a hotter top end? That said, I remember when we were both a lot newer, Scotts struck me as sounding a bit "dark" or "mellow," especially when going up against a Marantz 8b or something. Just a thought.

mark1101 Posted November 9, 2011 Share Posted November 9, 2011 The type of capacitiors used can make a big differecne and could cause what you are saying. In fact, the whole rebuild should be questioned. The resident HH Scott expert here is Craig at NOSValves. I would consult him. He will get to the bottom of it.
