I finally got back to working on this one again. It has a pretty nasty hum in it that is affected by moving the 35C5. I have cleaned the pins and tightened the socket. I already replaced the weak rectifier tube and of cource the electrolytics. Also I have re-stuffed all the paper caps. The voltage is good now. I think I need a 35C5 tube. Any recommendations?  I looked on ebay but I thought I would ask here first before buying one.

Oh and here's my first time capacitor cooker seen below. It's about 75 watts and only takes about 5-6 minutes. And does it stink! It's an outdoor activity only.
Thanks
