Siemens EL34s

Posted by Chris Spafford on April 9, 2003 at 08:26:02:
Hello; in the late 1980s/early 1990s, as cool vintage gear prices spiraled out of control, and my amps at the time (Heath W3s with abour 6 seperate Lamda and Sorenson dinosaur tube reg DC supplies sourcing them) were great but required constant attention, I was strongly swayed when a friend purchased a pair of VTL deluxe 225s; I like their simple topology, they looked pretty cool, and the front end of his system was so great that they sounded like pure magic compared to my Heaths (it was the front end)Sooo, I took the plunge and bought a pair of VTL compact 100s. I'll cut to my point, which was the mini version of the VTL "book" that came with them-- they referred to a German Siemens EL34 that could take 800 Volts on the plate and be coasting; I of course bought 16 of the National branded EL34s that were made in the late 1980s. Of the 1st 8, 5 failed in the first 24 hours. They ALL failed in the next few days, so I'm assuming there is an older production Siemens D. Manley had in mind... I saw this ebay auction.... Iz These them? These look a bit.. "funny" somehow... but could someone clarify as to what is the "GREAT" Siemens and how to identify it in the wild? Thanks! Chris
