Many old-tube enthusiasts still use them . NOS tubes go at a higher premium than the only available new Sovtech or defective Chinese ones cause they're better quality. Why not use equipment extant to when they were produced ? And will any of the logic analysers, for example, of the present era still be functional in the year 2040 ? Even more off-topic; but many high-end audio people are spending big bucks for tube-emulators to breathe the life into their digital CDs., that I get, matter of course, on my 45 year old EICO tube amps. I have a model 625 I use for old audio equipment. If it's anything like my m.625 they're a neat little machine. They do the job. I don't know if the settings are the same for the 635. Ask on rec.audio.tubes and/or rec.audio and someone should know. If so I'll see if I can get a scan of my sheets and send them on to you. Bill I'm shocked. Hope that list name was chosen in derision of the throw-away generation. : ^ )) ciao larry lwalker(a)interlog.com
