[QUOTE="Ampdog, post: 762266, member: 144"] Kubusi, Since nobody seems to be interested in valve data manuals, let me add a few matters. Yes - but fortunately not often asd you say. Those used to consulting valve manuals might also not fall for 'dangerous' differences. Somewhat alarming at the time were errors or approximationes in Valve Tester Manuals. (The way valve testers operate left room for interpretation - but that is another topic.) What might be more serious these days with conveniently available internet data, is glib misinformation regarding equivalents. Some 'exponents' seem to think that same pin-outs, description and smaller than 50% deviation in characteristics establish equivalence. Comparison of circuits by hearing only strengthens this.
