OK I NEED HELP - REALLY I DO ...

I AM PLAYING WITH A MICROWAVE OVEN -

WOULD LIKE TO REDUCE THE POWER OUTPUT OF THE MAGENTRON -

AS IT IS - IT IS SETUP FOR 600 WATTS PULSED ERP - THAT IS SHE PEAKS AT 600
WATTS 60 TIMES A SECOND -

ANODE VOLTAGE IS 4500 VAC THROUGH A 125 VAC STEP UP TRANSFORMER.

I WANT TO KEEP THIS VOLTAGE BUT WANT TO REDUCE THE CURRENT TO REDUCE POWER.

BEST WAY I THINK IS TO REDUCE CURRENT ON THE PRIMARY 120 VAC SIDE OF THE
TRANSFORMER.

CAN'T REDUCE VOLTAGE OF 4500 VAC BECAUSE MAGNETRON FAILS TO OSCILLATE AND
DRAWS A LARGE PLATE CURRENT.

ANY IDEAS ? ALREADY TRIED A VARIAC ON THE PRIMARY - IT REDUCED VOLTAGE BUT
DID NOT REDUCE POWER UNTIL THE MAGNETRON STOP OSCILLATING COMPLETELY.

ANY HELP WOULD BE APPRECIATED
