Update! I finally made some decisions and settled on final values for various circuits in the MC10. 3CB993B3-1ADB-4B10-9077-B5A9065120CE by andrewRneumann posted Jul 30, 2020 at 3:02 PM When you've got so many options, it's overwhelming. I've got some thick callouses on my playing fingers. Haven't had that since my college days!

Changed target bias settings for 2nd through 4th stages from Cold-Hot-Cold to Hot-Cold-Hot. 2. Removed cathode bypass from 2nd stage. 3. Add switchable cathode bypass to 3rd stage. 4. Added a choke to the power supply. 5. Incorporated a low-impedance attenuator on the 3rd stage load resistor that feeds the tone stack and 4th stage. This avoids an extra voltage divider after the tone stack and the issues associated with that design. 803E7F13-6A44-4B9C-A077-9F2304CE09D3 by andrewRneumann posted Jul 30, 2020 at 3:02 PM EAC2A6D2-A583-4A94-9FB3-93BFE8EAA1A9 by andrewRneumann posted Jul 30, 2020 at 3:02 PM I just got my Presonus iTwo in the mail. I'll be hooking the MC10 up to my Mesa Studio 1x12 cabinet and making some recordings. I'm going to smother the cabinet in moving blankets with a Rode NT2 I've had in storage for years. Crank it up! Thanks everyone who's taken an interest so far and thanks for putting up with all my questions! This is a fine group of people.
