Could someone draw me a schematic for a Mic preamp please? I have an idea for a preamp but my schematic software keeps crashing.
My idea is to use a pair of BC549's and 2N4403's (one each on +\- inputs from XLR) to create a balanced input stage, followed by a THAT 1512 preamp stage and a Triad TY-250p transformer balanced output.
Maybe I could give someone a few working TL075's pulled from sockets as payment? I'll upload a crude hand drawn scheme in just a moment.
Essentially this (https://www.google.com/search?q=transistor+balanced+input+mic&prmd=isvn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiCtcilneLOAhXC7SYKHZJ8A8wQ_AUIBygB&biw=601&bih=962#imgrc=bpfPIVskd3OM4M%3A) but with a Triad ty-250p balanced output. If someone would draw a schematic and PCB file, I would happily send them a few tl075's.
Also, replace the +\- in with xlr symbols and etc.
