Mam Neri,

Mam ung totoo may problema ba, ang pagkakaalam ko at namin lahat masaya si Mam, coz masaya lovelife ni mam, though pag nagdidiscuss si mam:

Bigla nalang, isisingit na MASAKIT MAG ASSUME, oo mam alam nanamin yan, tapos sasabihin, Ano pipiliin nyo ung positive o negative quadratic kase... Syempre ung positive, kaya dapat pag nagaasume kayo ung TAMANG ASSUME na talaga, di UNG ASSUMING ka lang kase MASAKIT... Tapos kaming lahat tawa, coz last week pa si mam, tapos may instance pa na ganto SAMA NG SAMA DI NAMAN SINASAMA, DI BA NIYA ALAM YUNG PRIVACY, ung magdadate nalang kayo may sasama pang kaibigan, Edi wala na kayong privacy... 

Tapos kaming lahat OONGA!! hahaha :D In the end sabi naman ni mam, bakit nyo ba linalagyan ng meaning mga sinasabi ko, kase mam may hugot talaga..

BIASING OF A TRANSISTOR 2

 NEED FOR BIASING OF A TRANSISTOR

Amount of bias required is important for establishing the Q- point which is determined by the mode of operation desired.

If the transistor is not biased correctly, it would

Work inefficiently

Produce distortion in the…

Installing JJ KT66s in a Sunn Model T reissue head.  The bias needs to be dialed down to get 60mA per side, as these run hotter than the average 6L6GC.  30mA per tube at this amp's plate voltage (489V) yields a nice 60% plate dissipation.  Definitely thicker when cranked, but doesn't seem any less loud than 6L6GCs, even though it's 25W dissipation per tube, instead of 30W.
