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.
