Seeing as how the main smoothing can C33/C34/C35 will need replacing I decided that in preparation I would removed the Main Deck. Glad I did as I think I found something relevant.

I Followed the Bush dismantling procedure for the Main Deck and took my own notes and took photos. It boiled down to six steps with 9 disconnections.

Now I can see the full extent of the Smoother bulge quite pronounced, now to the interesting bit. I also discovered the cause of the dripping wax, It was coming from C31 a .05 Huge BIG waxy!

It would seem from reading the circuit description that C31 along with a resistor (R43?) are connected between the mains input circuit and the H.T. line to neutralise residual H.T. mains hum. I think I just found the source of my HUM...................

I find using the Bush manual and the Trader sheet actually works best for me as the Trader offers me the benefit of circuit description, Even though the component labels differ.
