> One difference between the 10544A and a 10811A is that the 10544A requires +12v on pin 8 in order for the heater to turn on.  Without this signal, the heater will appear to be dead, even with the proper voltages on the heater pins.  So, you may have difficulty using a 10544A as a direct replacement for a 10811A.  I have also had difficulty finding specific information on the 10544A, but other have graciously offered a 10544A schematic, which I have, and could forward to you if you would like it.
