Hello, The Plate voltage meter in the 4K ultra reads high, so its time to replace the resistors. I'm looking for some precision wire wound, axial molded, flame proof, 1% 2W (min) resistors. I need a total of 10M Ohm, so single 1 M Ohm, (5) 2M Ohm, etc... will do I have not been able to locate a source. Can anyone help point me in the right direction please 73 Saad N5FF
