A very simple method would be a relay switched B+ with the relay being triggerd by the bias voltage. Either have the B+ on a spearate transformer which is switched on through the relay. Or have the relais in the ground connection to the center tap. If the bias voltage fails, the relay opens and B+ is drained through bleeder resistors and power tubes. If the bias voltage doesn't come up at turn on, the relay stays open a ako neces puno da se patis imaju i one gotove plocice za automatski bias Auto Bias Modul for two Tubes (Single pcb to Control 2 Power Tubes) | eBay WWW.EBAY.CA Find many great new & used options and get the best deals for Auto Bias Modul for two Tubes (Single pcb to Control 2 Power Tubes) at the best online prices at eBay!

ja slusam ovo pojacalo sa sluskama koje su 600R i nemam zamerku na gain uopste, niti hod volume pota 6SN7 nema kond u paraleli sa otpornikom u katodi, tako da je pojacanje sigurno manje nego sto si naveo nisam nikad merio velicinu izlaznog signal u odnosu na uzlaz, moram probati

jel neko mozda slusao one Chord male dakove sa FPGA chipovima?

da li si siguran da taj album uopste postoji u SACD formatu, posto ja to nisam nigde video

da

ne znam da li je lepo, ali je zanimljivo

prvenstveno da bih mogao da merim VT4C i ostale cevi koje rade na malo vecem naponu, takodje neg napon ide od -100V plus: Compared to the uTracer3 the PWM frequency has been reduced to 1.2 kHz. This makes the effective heater voltage virtually insensitive to parasitic wiring inductances, resulting in more accurate heater voltages
