Well..,this is only tube mic shematic that I can find parts(most of) in my loving country.I'm asking for help with transformers & schematic (http://www.tangible-technology.com/tubes/1566/1566.html).How to use=wire cheap transformers like oep,virgotronix,neutrik...& capacitor C2 i just can't find
50 mf/50v,only 47mf/63v is similar(electrolytic bipolar).I'm not planing to make audiophile quality,hi-fi studio mic pre,just a musical toy as preamp & di for Yamaha AW16g mixer/recorder,or for guitar tube amp.The local electricians don't give help,only soldering for $,so you have to give them schematic ready & components...
That is still good enough because i'm not playin' with ac/dc:vampire:
Cheap tubes(12ax7..maybe 12au7,ay7),cheap caps,resistors,cheap xfmrs so the sound will be cheap too😕 but that is ok for me!Don't ask me why.
Whatever the reply is.....thanx😉

An externally hosted image should be here but it was not working when we last tested it.
 
you opened too many questions in just one post ;

it's obvious that you don't know anything about making mic pre , especially with high voltages in tube gear , so you can't expect from anyone to give you all needed help in one post ;

first - you can ask for recommendations ( schematics) , but only if you write your needs and goals .

anyway - we told you so few hours ago on our local forum ;

make your criteria list first , then ask - exact things .

btw. exact link you posted must be something like this : http://www.tangible-technology.com/tubes/1566/1566.html
