Hello, I am repairing a LeCroy 9300 Series Oscilloscope. The specific model # is 9384AL, but I believe that information on any of the 9300 series should apply. The problem is evidently a burned out transistor and pot on the vertical deflection circuit for the CRT, but due to the burn damage I cannot make out the manufacturer's part # in order to find a replacement. If anyone has a service manual and can either provide a copy or simply reference the two components I am examining for me, it would be much appreciated. The parts I am interested in are referenced on the PCB as:

VR203A or Q202 - the BJT in the deflector
VR203B - an adjustment pot connected to the BJT

Again, these components are on the CRT board, which also houses the suction cup that connects directly to the CRT.

If anyone has one of these or has a service manual and can offer any assistance, it would be much appreciated. Feel free to reply here or PM me if you would like to help me investigate further. Thanks!
