Folks, here it is, my most expensive mic pre so far: RED!
(Does anyone remember the 1974 King Crimson album? )
Some details: for what reason ever I wasn't able to get something close to 24V from the PSU, so I decided to use a second power transformer
and Joe Malone's AC/DC for the 24V and 48V rails.
The wonderful but expensive Sowter 9970/9980 transformer combo.
More guts, the meter is an old Westinghouse, buffered by a JLM meter buffer. (Again, I can only recommend these)
I've implemented the Squish option, it gives some 1-2 dB of 'gain reduction' and adds some wonderful K2,3,4 etc. distortion to the signal.
Signal to noise: I've applied a test signal, set the Pad/Gain to get an output level at 4.37 dBu. I've muted the input signal: noise at -85.6 dBu. Not bad for a tube mic pre...
The case is a 3 RU from Modushop, custom painted front panel engraved by Schaeffer. Tubes are from Tubeampdoctor.
Thanks to Guavatone/Charlie for this great project.
