wow thanks for introducing me to the community @UntilThen. really appreciate it as the first steps are always the hardest . Will take me awhile to digest all the information available in this thread. Something to think about until glenn can start on the amp.
Before getting something, i usually like to research deeply and know what i am getting into before committing. think maybe it has something to do with my engineering background? However, this tube thing is really beyond me with all the many different tubes and its purposes. So apologies to all in advance if i come across as relentless or excessively pertinacious.
@L0rdGwyn and @UntilThen I think glenn has mentioned that he is using 2 x 6j5 instead of one 6ns7 as well. In fact, he mentioned that he is using the gec l63 that you recommended as well. can anybody enlighten me on the pros and cons between the two? i know 6j5 is just half of a 6ns7 so any difference might be tubes cost or longevity? on another similar note, is 6 x 6bx7 and 2 x 6as7g power tubes different in terms of sonics?
From my limited research, an extremely simplified demonstration of the otl amp is as follows: power from the socket goes into the transformer, ac rectified by rectifier stage to become dc, signal 'prepared' or preamped by driver tubes and then amplified and changed into ac by power tubes? Therefore, there are usually three classes of tubes, mainly rectifier, driver (preamp or input) and power (output). Please correct me if i am wrong.
Hey there, to play the devil’s advocate. Get a GEL3N and forget about all the tube rolling “madness”.
