Re: Rare blaupunkt 3 in 1. Sevilla 7555 / 7557
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.
