CSUB_ECC-LH Capacitor Substitution Box
Use: Preamp and power amp cathode bypass, high values.
OK, I admit it. You can calculate circuit values until the cows come home but sometimes it’s so much easier and faster to just dial it in. I’ve been a ham and involved in engineering for over 35 years, and I gotta tell ya, these are undoubtedly some of the most indispensable tools I have ever had.
For the Capacitor Sub Boxes, I decided to provide the most common values that we typically see in guitar amps. Just like the resistor sub boxes, it seemed pointless to include some oddball values that we wouldn’t use anyway. The poly caps are rated at 637
