The power supply that I used as a laboratory power supply to test tube preamps! Just 25EUR + shipping

Output:
for filament - 7V > 1A, there is a milliammeter
To the anode - 40V >100mA, stabilized

The power supIMG_9561.JPGIMG_9565.JPGply is professionally handmade, but inside there are factory-made PCBs! Not breadboard or AliExpress.
 
All is good with this PSU. Can make video how it works.
Just situation is that right now I’d rather get rid of some things usefully than “make money.”
 
Good to hear that. A few inside and chasis pics would help people decide if they can mod for more common voltages.
