[QUOTE="GordonW, post: 2247953, member: 568981"] If anyone wants to talk reliability, I can only mention: a) Set of McIntosh MC30 monoblock tube amps, and the accompanying C-20 tube preamp... bought by the ORIGINAL OWNER in 1961 (!) and were STILL WORKING when they were removed (and replaced with MODERN tube amps, he wanted remote control and more power) in 2004. And he used them an AVERAGE of 8 hours EVERY DAY (he was a dentist, and had his practice in his house, where the system provided background music in his office ALL DAY every day). b) My Harman-Kardon Award 300 integrated amp. Got it from a guy who was going to throw it away... only thing wrong with it, after THIRTY EIGHT YEARS, was a bad volume control, which had caused an overload in one channel, which used up one of the output tubes. A new volume control, two new tubes (I replaced them in a matched pair) and two new coupling caps (for insurance sake), and it's working LIKE NEW. Literally, thirty bucks worth of parts, and an hour to fix it. It now sits in my living room, and it provides a lot of fun for me and my friends to listen to. 3. My former (I sold it) Magnavox AMP185 tube amp... got it out of a console. Made in 1960. Replaced ONE RESISTOR, and it was perfect. All the tubes measured LIKE NEW on three different tube testers. How many people seriously think ANY of the modern "mass-market" solid state stuff is going to be working 40 years from now? Regards, Gordon. [/QUOTE]
