Hi Marc,

Can’t get 1k caps easily, local Jaycar has 630v caps which I use in all my Grundig sets. Will try these. The voltage to the vertical driver is 160v DC. The valve is a PCL82

I noticed on the schematic the tv chassis runs straight off the mains. All the heaters in the tubes are in series and connected to the mains ! I could not see an isolation transformer but will keep looking. If there using one I will fit one.

Yes I am very happy the EHT supply and tube is working.

Not many old B&W TV’s around these days. Either scrapped or on sheds hidden.

David
