Hi Charles , according to my data sheets on the transistors and the connections
of the resister on the circuit board , both ends of the resister connects to the
base of both transistors . Thanks , I will try changing out the transistors .

OK , I will try to be more specific with the problem of the circuit . The
carbon
resistor that is burnt is connected on one end to the base of a MPS A92
silicon high
voltage, general purpose amplifier transistor . On the other end of the
burnt carbon
resister is connected to the base of a BUV46 silicon NPN power transistor
for switching
power applications .
If someone would please look up the 2 transistors and calculate the proper
resistance
for the resistor that is burnt would be greatly appreciated . Thanks for
all the help ,


If you want to experiment, replace both transistors and put in a 1000 ohm
resistor. Probably not a base connection on both ends, by the way.
