DIY upgrade for tube systems! Lamp straighteners, EZ80 (81), is sufficient to deliver a cloud of electrons, from which flashed lightning current, voltage regulated and stabilized with ECL86 lamp, and thus, preparing pre-amp or buffer, sound rhapsody! Delay anode voltage, during the heating lamps is beneficial to them in the form of a drastic increase in work time!
