      Thank you for the information . I got the radio turn on right now . and it sound good when there is no one on the side and it doing good right now other then the hum . Yes I will be working on that this week . what I am also looking for is a tube schematic for something I can build for 80 meters so I can build my own . that will be fun .

        I have a BC-348 that had a similar problem: bad hum.

        It originally used a dynamotor. Previous owner replaced this with an AC power supply. But...the dynamotor negative lead origially ran to a DC bias point that in turn connected to all the grids of the tubes...i.e. : they got their negative DC bias via the ground return of the dynamotor (resistor to ground in series with negative lead).

        When an AC supply was added, this bias point was simply used as the solder connection for the minus lead of the 200V high voltage AC supply. BUT...With the dynamotor, you have DC (from the DC generator) and so no hum but with an AC supply there is no filtering in the negative line (normally). Lots of AC hum.

        Cure was to use a LARGE capacitor between bias point where dynamotor negative lead originally connected to ground, negative lead on cap to point, poistive to ground. I think I used 5,000 MicroFards. This removed all hum.

The first schema is a mixer and rf anten preamplifier, a very successfull device but not a TRF receiver part. But this mixer can place in front of the TRF receiver, The others is about TRFpart. Ones is an audio. the the real schema is two parts. the address is

            Thank you for the information . I got the radio turn on right now . and it sound good when there is no one on the side and it doing good right now other then the hum . Yes I will be working on that this week . what I am also looking for is a tube schematic for something I can build for 80 meters so I can build my own . that will be fun .

But...the dynamotor negative lead origially ran to a DC bias point that in turn connected to all the grids of the tubes...i.e. : they got their negative DC bias via the ground return of the dynamotor (resistor to ground in series with negative lead).

BUT...With the dynamotor, you have DC (from the DC generator) and so no hum but with an AC supply there is no filtering in the negative line (normally). Lots of AC hum.
