Hi Said Jim, I meant John..
Another advantage, in tracing down excessive noise on 40 M with a
ham buddy in Maine this summer I found several cases of neutrals and
grounds tied together (at locations besides the main panel)
throughout the house and shack. Clearing those (and some other
stuff) reduced ambient noise from S7-9 to S3 on his 40M rotating dipole.

Hi Jim,
I understand that the update to the National Electrical Code now dictates
that all NEW work 220V outlets have a neutral in addition to the ground. This
makes good sense, especially in light of your email. Buy the way,
legal or not,
The Collins 30S-1 amp had an internal 120V outlet under a shelf in the power
supply. This was to facilitate installing the power supply for a
KWM-1 within
the amplifier PS cabinet. I don't doubt that other manufacturers and
homebrewers do similar things with blowers, relays and control
circuits. Dangerous? I
suppose under the right circumstances it could be. For once, I can go along
with the NEC folks.
73 and stay safe,
John, W4AWM
