Mondial is correct, I just measured from the junction of the 32K and 50K resistor and indeed it is going to all three tubes grids for an increase in current! Another case of the missing dot. Mortz, you were no doubt correct in the current draw based on the schematic. Seems like about a year ago we "discovered" another missing dot Mortz on a members schematic. Pith, looks like you need to go per schematic and boost that 32K to 2 watts. I don't have one so will probably parallel a couple 1 watt resistors. Mine is reading over 50K. I corrected the 42 driver error per the 18 schematic, thanks Mondial.
