MaCo 300 amplifier

[Gman]

Why do some MaCo 300 amps have 2 power transformers? The 300M schematic, Im guessing is the mobile version (12v), showing 2 transformers, well the schematic symbol for 2 transformers, but I see other chassis' with 2 transformers yet a 120 vac ac cord. The 300B schematic, I can only assume is the base model, and shows just 1 power transformer. Would like some clarification before I buy one. Thanks.

The Maco 300 isn't a product name, it's a product line. It would get redesigned every production run, seemed like.

Five, tubes, six or seven. One power transformer or two, two fat Foster's Lager-size filter caps or three skinny ones.

Grid-driven driver tubes (grounded cathode) or cathode drive (grounded grid).

Like a box of chocolates.
