PTL (power transformer less) design of vacuum tube amplifiers

[VectorhornPSA]

Hello. Many years I use PTL schematic in all my VT amplifiers. I like it so much! What do you think about? Who try same exotic design?

P.S. Warning. Don't over turn L (live) and N (neutral) poles or use power protection circuits!

It is not so much an exotic design as well as extremely dangerous! This is diyaudio - many here do not have the required experience/knowledge to do this safe.

Thread closed. These type of non isolated power supplies are deadly.
