Quick question - on page 65 of the instructions, 32U and 46U should be adjusted until 175 VDC.  Should this reading be the same (or adjusted to be the same) after the DC heater mod is incorporated? 

Thanks,
Matt

This voltage is the plate voltage of the 5670, the DC heater upgrade DC heats the 300B, so the voltages shouldn't change once that upgrade is installed.
