    To any and all S/S amp designers

    ...not copiers! I have a one-off job up for grabs for a negotiable fee. Here's the schematic of one of my Metron/Transword Communications amp's: I would like this circuit modified to incorporate 16 X 2SC2879's. So that requires new input splitter, output combiner and hopefully a superior...

    Question for the brain trust

    If you have 16 matched output transistors in a push pull PA can you optimise bias with a single pot as in my amp here; or is there an advantage in being able to set the bias to each pair of devices? Phil Unit 148

    Bias Adjustment???

    A questions for the experienced amp designers here. My Metron HF 8 device amp has a single bias adjust for the four push-pull pairs of transistors. Am I correct in that if all transistors are perfectly matched or at least share the same batch code then this single adjustment is probably...
