[QUOTE="Steerpike, post: 798607, member: 807"] 50-0-50 AC is [u]very[/u] high for a transistor audio amplifier, except one of really high output power, and then 4 amps isn't enough current. (Using a single ended supply (0-50) is possible with modern transistor amp circuits, but not common or preferred because it requires a big output capacitor) Using a voltage doubler type rectifier it could get you enough B+ for a small valve amplifier, but you'd need an additional transformer for the heaters, and 4A of B+ current is ridiculously overkill.
