georgehifi7,414 posts07-23-2020 5:00pmThe Luxman 590 bench tested to 90 w into 8 ohm in one of the reviewsCan you post a link to this review please? Here you are, George. Presumably in A/B after 30W. The 'piddly small heatsinks' are entirely adequate for the amp. http://www.navratilaudio.cz/novinky/Luxman_L590AXII_HFW.pdf |
If anyone is interested in the Luxman L-590AXII, spend some time reading these 2 reviews. In the first review, the lab report shows a power output of 95W/8ohm and 165W/4ohm https://www.luxman.cz/data/test/test-en-l590axii-hifinews.pdf https://www.stevehuffphoto.com/2018/11/25/hi-fi-review-luxman-590-axii-integrated-amplifier-review-b... |
I can only recommend to you to read about my dreamed power amplifier.... Any ZOTL amplifier by David Berning.... The only revolutionary tube amp . new technology.... No heat, lifelong duration tubes.... This is why this tube amp interest me apart from the sound quality....I forget to say competitive price.... I apologize realizing that the OP search is about S.S. technology..... :) |
Nelson Pass is the Class-A master, and he says the Inter 60 has 30w-8ohms of Class-A on it and he uses that size of "external" heat sinks for it to dissipate that heat, and they do run very hot. Then the smaller "internal" heatsinks of the Lux are not dissipating the same amount of Class-A, especially "if" the Class-B wattage into 8ohms is even higher than the Pass Int-60 Things don’t add up with the Lux Class-A figure presented or the Class-B wattage. The higher the rail volts for higher Class-B claimed, then "for the same Class-A bias(30w)", the heat dissipation goes up exponentially. Cheers George |
