Hi Tom,
If you really want to regulate the oven`s supply voltage, my National
Voltage Regulator handbook shows that the LM317T will supply over 2 Amps,
with an input/output differential of between 5, and 12.5 Volts. A single one
of these should do the job OK.
Cheers!,.................................Don Collie jnr.
