Here's a ``quick and dirty'' one: neutral--------------------------------------------- | | control (phono) load (amp) | | | ___ | /\/ T1 | --- | /| | R1 / | |________/\/\/\_/ | | | | v _ | - ^ | D1-D4 v _ | - ^ | | | | live------------------------------------------------ R1 100 ohm (?) D1-D4 1N4001 T1 Triac, sensitive gate, > 2 * load current, 200V. Load voltage is somewhat dirty sine wave; an .1uF/200V capacitor across the triac is recommended. Phono current should be < .7A AC.
