From the halcyon days! American HiFi, the true golden era -- from a peak of around 1963 in this case -- this was one of HH Scott's 7591 integrated amps -- and a true gem at that. If the 7591 were a "car" it would be the Studebaker Golden Hawk ... a powerful V8 package in a classy, good looking suit. A non-overbearing, conservatively fin-tailed CLASS ACT, ready to take charge with clarity....with the look & sound you'll never really get tired of. There is a reason why the McIntosh 225 sounds amazingly good thanks also to the 7591 tube (well good iron too). In fact, Walt wrote many years ago in Absolute Sound that the 225 "bests" the 240 & others easily, and was the only MC amp he ever really recommended. A much later design of beam pentode tube, and born of designers want to have a really great fidelity ... and power in a small package. We also love it's progenitor the 6V6; and the 7591 gives you more bass. Luckily it does not really conceal any of the midrange. As a result, you get tight bass, and killer detail. And it's just an overall balanced, perfect sound it it's class of tube. As beam power tubes rode off into the sunset, they got smaller, higher power and HARSHER. Not the 7591 -- it's just right. The only real drawback to this tube is -- well --- it's pricey and getting rare. And, there are no relevant subs; at least none you'd want to bother with! That's OK, because the vintage 1960's SYLVANIAs in this Scott LK-72 were tested .... and PLATE CURRENT MATCHED. They're scoring over 100% (see exhibit B,C) on a dynamic emissions test (shown for easy reference) You'll be good on tubes for a long time.

This amp appears to be working flawlessly. I only tested two inputs, and EXPECT the usual dirty switches and connectors, that will dissappear with use. This LK-71 is mostly all original. The coupling caps and the recifier appear to have been recently serviced. It's been well cared for, and is mostly original. With a watchful eye towards aging caps -- as always.

Source in this case is 16bit CD player, and be sure to watch the SCOTT LT-110B tuber video -- it's soul mate from 1961-63, feeding Yamaha NS-10 type monitors.
