ARE YOU TALKING ABOUT THE HATACHI TO-3 PACKAGE OF MOS-FET'S? HAVE THE 2SK-135 &2SJ-50 N & P CHANNEL PAIRS, AND THE HIGHER POWER RATED 2SK176 & 2SJ56 PAIRS AS WELL. LET ME KNOW IF I CAN BE OF HELP. BOB

Don't write off the Sumo yet. A friend faced similar problems with an old Electrocompaniet. The output transistors which were bolted with two screws each on the heatsinks were no longer available. But a crafty repairman found the corresponding new transistors (albeit with smaller dimentions), drilled holes on the heatsink to screw on the new devices, and the unit is now fine.

you must try mark levinson. ive tried everything its the best sound. very musical

One can think of 20-times-2 plus 4-times-2 reasons NOT to get the ARC110b. The first 20, because it's a twenty-year-old piece of gear (not that it's bad for one to own quality stereo equipment for 20 years, but why buy NOW something that has definitely been superceded?). And the second 20, because it has 20 TIMES THE DISTORTION that a quality receiver currently has. As a test, borrow from a friend a recently manufactured 100-watt receiver. Crank that up with your ADS speakers and get ready for a revelation. Then go out to your local discount electronics store and for under $400 you can get a receiver with four or five 100-watt channels of state-of-the-art amplifier technology, surround sound and a remote control to boot. Plus 4-times-2 reasons more: the ARC 110b will weigh four times as much (92 lbs if the memory faileth not) and cost four times more. That's a lot of reasons.
