Default Re: Marconi 702 advice

The EHT is low because th previous restorer, with the rewound transformer,
changed the nature of the setup. There is now a 470K resistor between
the transformer and first filter cap, and the bleeder is 12 megohms. As
the picture is OK and I don't want to remove the CRT, this will remain for the time
being.

I remembered to look at the TRF response, and it is similar to the
response posted by somebody else above, except that the carrier
is well down on the response ... i.e. its truly vestigial sideband
reception using the lower sideband.
