[QUOTE="Skylar, post: 1126922, member: 17146"] Several FirstWatt amp designs employ autoformers in the input stage, i.e. M2, F6 & F7. The only drawback I can think of is that it's prone to picking up hum from the internal PSU, but nothing that good toroid placement and if needed, mu-metal strips around the autoformer can't fix. Example: M2 amp. [ATTACH type="full" alt="Edcor_autoformer.jpg"]19738[/ATTACH] [/QUOTE]
