hey peeps
I thought i'd start this thread because if need to know someone else out there does too...
(plz consider info offered for the layman/newbie/me... hehe)
Transformer questions:
1 how do you determine the proper input / output trafo for a certain tube type or tube set?
2 what are considerations for type of input eg. guitar , mic, line, balanced, unbalanced...?
3 can anyone elaborate on the subject of trafo ratios and how they relate to any given tube set?
4 without a schematic, how would i determine the correct phase of a balanced input/output for xlr connection? (BTW this will help me with my ba43/ba45 units)
5 how would i determine the proper power transformer for a given tube set?
6 why are seperate filament transformers used in some designs?
7 it seems a lot of vintage gear is elaborately laden with huge chokes, why is this trend not seen in slightly more modern designs?
8 i see a lot of different plate voltages: just how many are there ... what are the most common?
9 is a filament voltage always 6.3v
10 why do some designs have seperate filament for the power supply/ rectifier tube?
11 we see a lot of success stories: anyone have any warnigs/war stories/b+ near death experiences/ pics examples/scientific websites etc.. to elaborate on the dangers of DC voltage for newbies.
( hey i wonder how fast it would cook a potato haha lol ...or more seriously someones hand...hmmmm...not so funny)
I can't think of anymore right now.
everyone please add to this thread.
**ALSO** it might be a good idead to keep questions numbers consecutive for reference in the future.
please continue the number system i have started above.
thanks
