| Does anyone care to ask an amplifier designer a technical question? My door is open. @ramtubesYou wrote the following regarding ARC:Im sorry, but you asked. I'm sorry to be so negative about ARC, but I was a dealer for them from 1975 to 1980. If you have not heard about the "pink papers" thats a story in itself. ARC treats dealer... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Roger,You posted the following"As I tell everyone. Light loading can be done on any tube amplifier. If you dont play above 80 dB go to the lowest tap. If you play 90 go one higher, if you play more than 90 you may have to use the high tap to get ... | |
| Tom Tutay Transition Audio Design Preamp I hope Tom made it ok from the hurricane. I think he lives on the western panhandle of Florida. | |
| RIP Otis Rush Hey guys and gals, we be getting old. The artists we grew up with are getting old along with us. I recall reading somewhere that Paul Simon is retiring. RIP Otis. | |
| Paradigm Personas: A First Listen Audiotroy, ... add to the list of excellent speakers that use beryllium Magicos and the Revel Ultima Salon 2 and Ultima Studio 2. | |
| Which band IS really America's Greatest (rock & roll band)? Agree with the above, but add the Stones, Blondie, the Four Seasons and Fleetwood Mac. The Rumors LP is iconic. | |
| How about a list of speakers that are time and phase coherent? Thiels and what else? How about Vandersteen and Green Mountain Audio. Just my personal sense of aesthetics, but the top of line Vandies look like Dr. Who Daleks and the GMA Calypso HDs look like one-eyed preying mantis aliens. Just my humble opinion. lolBIF | |
| ARC Ref 5se VS ARC Ref 6 @jonaiken Some years back I seem to recall a conversation with Uncle Kevin about SED Winged Cs. Kevin said that some SED Winged Cs on the market do not spec all that well. I haven't checked UA's website in a while, but I seem to recall that at l... | |
| ARC Ref 5se VS ARC Ref 6 Where does one get Winged SED 6550 C tubes? I thought the Russian factory burned down many years ago and good quality tubes are hard to come by. I have read that the new variant 6550 is not as good as the original Winged C. | |
| I hate biasing! Roger,At first I thought the Ref 160 monos were a Ref 150SE split in two. Separate power supplies and power trannies of course. But a close look at the specs show some small differences. So maybe the Ref 160 does have some new bells and whistle... | |
| MAC Autoformers? Rodger,Take a looks at the specs for a Tung Sol 6550. https://www.newsensor.com/pdf/tungsol/6550-tungsol.pdfInterestingly, the 6550 "load resistance" is 3000 ohms. But the plate resistance is 15K ohms. The KT-150 spec sheet you showed us says t... | |
| MAC Autoformers? @ramtubes,Roger, take a look at the New Sensor specs for the KT-150. I believe it says the plate resistance is 3000 ohms.https://www.newsensor.com/pdf/tungsol/kt150-tungsol.pdfI thought you said before that if the primary impedance presented to t... | |
| Audio research Used to own the SP-9. Read the Stereophile reviews. It never lived up to its hype. ARC modded it two times. There are SP-9 Mk IIIs floating around out there somewhereI moved up the ARC line up and landed at the Ref 3, a very good linestage. I... | |
| MAC Autoformers? @ramtubes, I was in contact with Anthony today. I will ship off 2 quads of KT-150s next week that I bought from a 3rd party tube vendor. Hopefully, Roger can get some good matched pairs out of these tubes. Damn expensive!! Otherwise, it's bac... | |
