<DIV>Hi Joe</DIV>
<DIV> </DIV>
<DIV>I cannot advise on the LEDs but one of the pilot lamps (#47) is from
the 6.3v rail to chassis so if you remove that you will unbalance the two series
connected 6.3v rails. The other two pilot lamps (#1815) are only across the
12.6v line so they are not a problem.</DIV>
<DIV> </DIV>
<DIV>You will need to provide a resistor equal to the hot resistance of the #47
bulb to make the two 6.3v rails the same. Alternatively you can experiment with
low value resistors to see what is required to balance the two rails.</DIV>
<DIV> </DIV>
<DIV>You can use white or yellow series connected LEDs running from the 12.6v
heater rail with a series rectifier diode and a current limiting resistor. You
may not need to smooth the supply to the LEDs unless you can see any 60Hz
flicker which is possible but unlikely.</DIV>
