[QUOTE="ludo, post: 94291, member: 691"] The original output transistors were apparently 140V parts, the 2SD1047 and 2SB817 are similar. That is a bit close for comfort with 140 V between the rails even if the output node can't swing quite that far. (Benouend na aan die rand van die afgrond.) The more so if the "manufacturer" of the replacement output stage parts is a re-marking facility somewhere in India/China. [/QUOTE]
