Thanks Ron, great help.
--------------------------------
I am rebuilding the bakelites now and it is a major PIB as the guy flooded all the rivets and I cannot release the wires by cutting and insert the pin to push the block out - have to clean them first and while you do that the tar starts bubbling out of those rivets.....Not too bad but complicates it some.
Good thing is, as I go over them some tubular caps start to disappear as the guy threw them over the existing ones.
The guy was obviously a loyal Philco repair person as all the tubulars inside are Philcos.
But his judgement I do question as why would you throw a 0.006uF cap from one line to chassis when you already have 0.015uF there. And if those caps (which are death caps) are in question - why not remove them first (I take it Y-caps were not available back then).
I also question Philco's technique of mounting the filter caps across the line before the switch. This way they may be charged while the unit is Off and the plug is pulled out in an arbitrary moment of time and have no way to discharge so one could receive a little jolt by touching it. In todays line filters there is always a resistor across the line. Granted it is 7.5nF equivalent, won't kill ya....I still intend on soldering 1/2W 200K-300K resistor across.
