That's all seventeen black tar capacitors removed and replaced with Philips "mustard" ones. The special value capacitors arrived today from Holland. Many thanks to Jac for sending the 0.33mfd and 0.056mfd capacitors.
These are the capacitors that would have been fitted as replacements by a Philips service depot in the late sixties after supplies of the tar capacitors ran out.
So now the HT smoothing capacitor is to be replaced. I've found a 100 + 200 + 16microfarad electrolytic capacitor to replace the original part which can't be reformed. It's useless! The chassis must come out and the CRT removed to perform the HT capacitor substitution.

Meanwhile the line output transformer is still receiving the warm up treatment.
