Default Re: Regentone A133 HT smoothing capacitors, V4 cathode resistor

I got the replacement EL41 today and fitted it. With the new valve (NOS Philips) the cathode current is normal and the positive voltage on the grid is gone with the original grid leak resistor (680K). I have left the 220 ohm cathode resistor in place.
