Verified!
“Murder One” styled voltage multiplier for low-stakes tube amp usage–seven stages reaches around 89v, depending on diode losses.
Includes pads for onboard TO-220 voltage regulator; I used a 7812 and a LT1054 charge pump. A 7660 or 1044 charge pump will work (pins 1 and 8 are connected).
Excepting the 6.5mm filter cap, all caps are 5mm diameter and a tight fit. Diodes are optimally DO-35. Note that pads and holes are quite small.
Schematic follows frequencycentral’s design: ladder caps are 10µf/100v; diodes are 1N4148/1N914.
