message ... There are a couple of smoked resistors on the regulator board. I can not trust the ohm meter reading so I wanted to verify its value. I am trying to avoid De-engineering the board. Now once the resistors are replace there may be something else that smoked the resistors too. Paul. Paul - Where are these resistors .. the typical linear supply has low ohm equalizing resistors across the NPN pass transistors .. and only a few in the regulation circuit off the LM723 pins .. for example a 1 K is usually used from pin 4 to the voltage adjustment potentiometer. gb |
