WebFinale HF con la GS31b / GS35b. Finale HF con la GS31b / GS35b. L' idea di questo finale mi e' nata vedendo le valvole russe alla fiera di Friedrichshafen. I prezzi sono molto buoni, considerando che la 8877 in America costa circa 500 dollari, allo stesso prezzo si comprano quattro GS35b. Questo e' il circuito di bias: WebElectronic Dynamic Bias System EBS-1 or HF Amplifier auto-bias theory. The idea behind automatic electronic bias is a reduction of quiescent current and heat in high power radio-frequency amplifiers. The basic idea is when RF drops to a very low level, large amounts of quiescent current are not necessary.
