Hi Felipe

i use the single cap multiplier for the CFH7 and the AX-11. With a voltage drop of about 5V , and a supply voltage from 35-40 V, you have to feed in 40-45V rectified voltage. The physical dimensions are limited by the given lead space of the pcb, also you can adopt the use values for capacitors.

the dual cap multplier i use for my amp with +/- 52 V supply voltage with a 15000µF/63 V input cap and a 150µF/63V the gates of the IRFP240/9240

Hi Felipe,

the biggest disadvantage at +5V will be the voltage drop of 5V over the vertikal FET. So you will have to spend double of the power at input as what you get on the output. The same for use at filament for example, 6,3V + 5V (voltage drop at FET) at 2 A, you need about 12 V/2A at the input of the Capmu.

Hi sp

sure is no problem, Remember shipment and fees is about €4,8 additional and there is no insurance and tracking. Will be sent in a big padded letter.

Let me know, if it's ok
