Update: Just waiting for the front panels from the prototype shop. Won't be here until next week.
In the meantime, I found an old project I was working on back in 2005/06?
(Not tapers related, but since we're talking preamps here....
This is old school discrete design, home-etch PCB, Ferric Chloride, manual drilling and none of that fancy silkscreen, no IC chips, just plain old fashioned transistors and input transformers and output transformers running on high voltage DC.... yup... this guy is not "green-friendly"... Bigger is better, more is better, the more you live, the more you love.
Replaced and upgraded the PSU with my new PSU-4448 kit design. Replaced XLRs and just soldered all loose connections.
Output I measured is more than the limit on my oscilloscope.
Looking good at 50khz and I measured 46+ Volts peak-to-peak before clipping.
YES! 46+ Volts... which is not unusual since the whole preamp is running and requires a supply voltage of 48Volts.
Absurd! Overkill! But whoa!... the sound... it's phat and beefy and just too much... 46Vpp!!! Did you see the size of that output transformer?
This will bring into submission any AD converter that is unfortunate enough to be on the receiving end. It will slap that AD converter silly.
and now back to regular programming....
