richieb Posted October 10, 2006 Share Posted October 10, 2006 Hate to repeat myself but is anyone familier or has heard tube amplification using horizontal sweep tubes like those used in older televsion designs, types 6GB5 or EL504/27GB5. I have seen some examples of these amps and their design seems quite thorough and well thought out. The tubes seem inexpensive and plentiful which would be a plus. I guess there would be no reason to stray from the typical EL84, 34; KT88, 90; 6550 etc. tube types so long as performance is retained.

Mark Hardy Posted October 11, 2006 Share Posted October 11, 2006 McIntosh used a passel of 6JE6/6LQ6 color TV horizontal outputs in the gargantuan MC-3500 amplifier. These were used as inexpensive tubes for RF linear amplifiers (e.g., CB radio "heaters"), too! Of, course sweep tubes can be used for audio. I think several of the OTL (output transformerless) tube amp designs use sweep tubes. I wouldn't necessarily expect the nuance of the tried and true hi-fi output tubes, though. They still make 300B's, EL84's, and 2A3's (to mention but a few) for a reason! http://www.webace.com.au/~electron/tubes/Mac/MC-3500.html http://www.webace.com.au/~electron/tubes/Mac/mc3500b.gif'> Quote Link to comment Share on other sites More sharing options...
