John,

     Here is one more item to add to the previously sent HW-7 Service
Bulletins.  I have included the other groups so it can be also added
where needed.

HWA-7-1                                         Bulletin No:
AC Power Supply                                 HWA-7-1-1

                                              AC HUM

AC hum in the HW-7 from the power supply can be eliminated by installing
two .005 UFD 1.6 KV capacitors [PN 21-44] from the transformer secondary
to ground.
