Re: Transformer design, tube data

Andy	Re: Transformer design, tube data Hrm...OK, I think I get it now...the data sheets are simply telling you what to expect when certain criteria are applied...for instance if I choose to drive the plate at voltage 'A' I can expect this to happen, and if I drive it at voltage 'B', I can expect to see this...makes sense now. I was of the belief that they were actually specs to be followed, not a 'if you do this, you'll get this' scenario. Thanks for clearing that up for me, that has been one of the more confusing things. So simple. I found your specific example on the N7JP database site with no problem. So this other guy probably has a different sheet that provides a different plate voltage and so forth and therefore has a different plate-to-plate imp spec. Now, one more stupid question...do I need to do anything with the impedances when figuring out a tranny requirement? For example, 1 6L6 ( from your example ) drives into 3.8k ohm impedance...would a pair drive into 7.6k, a quad into 15.2, etc, or would it always remain at 3.8k? THanks for the answer, you have cleared up a lot of stuff for me already! Andy
