Re: EL509 and EL519

pickel, hi. tubes very similar. dissipation slightly different. peak anode current different. if you don't have a tube manual look up characteristics for these two on Duncan Amps web site. If you are into tubes get the reprint of the GE Essential Characteristics book published by Audio Amateur: lots a resellers including Antique Electronics Supply. Every "bottlehead" needs a tube manual. :)
