I just looked at the primary to chassis and see the transformer is leaking
AC to the chassis so sot good..

I'll have to look for a replacement

Would be nice to know what voltage the secondary is, so could sure use that
info..

I'm thinking the secondary HV should be 230V  to 250V

Next winding 20/24V

Last winding 13/14V
