. I don't have the correct valve as a replacement it's got a N389 so I will give the magnet a try just to see for now. Then get a replacement .
I will change the main cap as John suggested. It's a 100mf x 300mf
It does test ok but about 50 % higher in value .
The only new ones I have are 150 mf and 330 mf I assume that's ok
Thanks everyone Andy
