EZ80? Other?        It would be really nice to know whether the OPTs have more than one tap.        You write that this is from a console - is there a brand on the console?        Do the transformers have open coils (paper showing), or metal end-bells?               Magnavox made variations of these amps in their uncounted thousands. And they       made them for many 'brands' other than their own. But so did Knight, Olsen,       and a bunch of others. So more detail is needed to even get close to any sort       of ID. In any case,        your best bet is to draw out the schematic for yourself before looking to mod       it. And note that these amps were designed to be as cheap as possible to       manufacture, not necessarily a bad thing, but you need to be aware that every       part and piece is being        driven to, or even a little beyond, its proper design limits.               Peter Wieck       Melrose Park, PA              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
