Philco radio cap problem

[radio nut]

Well, I retried my set and I am back to square one. Same problem again, blew my last 1lb4 output tube( too much heater voltage). The cleaner I used last night was an older slow dry type. I even took a hair dryer to it today to make sure it was ready to go.Well, I had bought the last 1lb4 tube that Fair Radio here in town had so I will try to go there and search the "back stock" to see if I can come up with another. In the meantime I am going to unsolder one end of every cap in the set and use my heathkit to see if maybe that cleaner although it was not the lubricating type, being it was slow drying did soak into a cap and short it out.The one thing I would really like to ask someone from Philco is why was this set not a "clean "series string as far as heaters went.Why all the side taps into B+ lines and junctions to IF secondaries?I was thinking that my overvolting issue was from a leaky cap tapped into a B+ line.I guess I will find out soon(not soon enough)!
