[QUOTE="Ampdog, post: 46502, member: 144"] Handsome! Thankyou me man. I missed that somehow. Not then continuing on that reference, but perhaps just two last general points: This is where the 'percentage (of the output) distortion's shortcoming comes in. It does not directly show the magnitude of the undesired products. One must keep in mind that there is also a human limit-of-hearing level. Thus 1% of distortion at a low output level might be below that, whereas 0,1% at a higher level might not. Then in the second last paragraph: There is, with all respect, this notion in mostly American magazines that the Williamson used pentodes in the output stage. It used [I]triode connected[/I] pentodes (KT66), thus triodes in every characteristic. (Characteristics are all over the internet.) Handsome ... ??? In which moment of weakness did I indicate other designs? OK, if referring to the 100W (p/c), that is still mildly in production - thus I hope to be forgiven for not showing that in every detail. But I will simplify a circuit diagram down to essential details for comparison only. (It is strictly not a home 'buildable' design; special components and the like.) [/QUOTE]
