BULLETIN # 10
MODEL: TR-7400A
SUBJECT: ARCING IN FINAL SECTION
There may be some cases of arcing to ground beneath coil L-6
at the collector of Q-2 (2N6083) inside the final unit X45-1090-10.
This is due to minute differences in the circuit board trace
dimensions and a residue of flux on the board.
If this should occur, remove L-6 and clean all traces of carbon
and flux from the circuit board. Resolder the edges of the traces
and remove any flux left from soldering. Modify L-6 so that it will
stand off the pc board.
Reinstall L-6 and check for rated output.
A slight retuning of TC-4 may be required.
