MS9700 secondary voltage

I am working on the same situation. DId you first check to see if it isn't the fuse that has blown? Radio Shack has a 4 pack of 2 amp fuses for $2.49 which I think will work. Their catalog number is 270-1064. These as 5x20mm in size (the 1-1/4 x 1/4 inch is way to large) and they are slow blow - designed for this type of household equipment to protect from short circuits and power surges.
If you are lucky maybe it is just the fuse. Since I can find no other information about this unit - especially the transformer - I'd check eBay for a working one. If you can get it cheal and it works test the power output with a VoltOhmMeter (VOM) and once armed with the info you can let me know too what the output is <smile>. You can then get a new transformer - have 2 working units - can keep or sell one to recoupe your eBay purchase. Just a thought. Hope it is only the fuse.
