that's correct
..on the set having a thermal switch; one side goes to the single section 160uf@250 is on the positive side of the caps center leg; going too the thermal switch,and on to the filter choke..the negative is to the safety fuse holder,and one leg on thermal sw is going to the power switch
the single cap is not grounded...this must be a simple fix..i hope i've not damaged this 53 year old set..it has a beautiful cabinet
