[FS] Maida HV Bi-Polar regulator Full-assembled

Hello,

that's a project of mine. I have used them for an old project with tubes.
Two power supplies available.

Each Pcb has on it two maida's HV regulators wired for output bipolar operations. AC in, +/- DC OUT.

Has a set resistor to set the "center" output voltage, and a trimmer to refine it (+/-10% around it).

MAX AC-IN 500v
MAX DC-OUT 500v
max output current (per rail) 800mA
15V dropout

the maida iteration used for that powersupply is inspired from the awesome work of Tomchr, he called the 21st century maida.
Take a peek HERE and HERE

[the pcb is easily hackable to split the two rails and get two positive (or negative) rail, instead of the bipolar configuration.]

Boards are cleaned in a ultrasonic bath after soldering in order to remove any nasty residue.
All the components from Mouser.

Price for one is 80€ fully assembled.
140€ for both of them

Shipped everywhere.
Paypal payment.
