Triode_Kingdom - would you mind sharing where you purchased the Ultrasonic Supply? Also, does it support 4A or more? Any other specs you can share?
Finally, have you compared the Ultrasonic AC vs. battery filament supply? I am currently using battery (un-regulated) but the battery charging is a PIA.
This post is made possible by the generous support of people like you and our sponsors:
