Q101 comes as a kit (160082) that includes;
Q101
R102 3.3 ohm
R103 47 ohm
R106 2.2 ohm
Q100 142251
CR105 and CR108 142569
Also check R109 2.7 - 22 watt. Check the B and E connections to Q101 or
better yet solder them into the socket when the repair job is complete. I
have had 1 failure of Q401, the chopper driver. John.
