The Zener Diode (33v) goes short and blows the 4.7 ohms resistor next to it (Yell/Mauv/Gold/Gold).
It is best to check all the caps on Power Supply, as many will be iffy, note that they are 105 degree caps.
The 33v zener is next to the two pin socket marked 32v.(Its 1.3watt)
On my one I had to change seven caps, some swolen some OK. I have an advantage as being an ex engineer I have a cap tester, earnt its expense when new(£150)
