Philco 41-608 Volume and tone control function ++
#1

Hi,

In restoring this radio, I had to replace both the volume and tone (Bass) controls. The tone control calls for a 6 meg
but was able to get only a 4 meg. The volume control is a 2 meg with a 1 meg tap which is the same as original.
Since the radio didn't work hardly at all before, I don't really have a comparison available but was wondering if what
I am noticing is normal.

The volume control seems to have an area around the middle of it's travel that makes the tone change to a much
more treble sound... higher pitches, and then back to a more normal tone as it reaches maximum.

Also the tone control starts out with the sound being a bit flat... mostly midrange tones, then increase to a very
prominent treble sound... high pitches, and then finishes off with more normal sound with a bit more bass at max.

These seems a little erratic in that the volume control seems to also be changing the tone and the tone control is
not a very linear change but rather a flat to treble to bass action.

Is this typical or what is anyone's thoughts on this behavior?

When I reach the more bassy end of the tone control, it often makes the audio very muffled and probably distorted.
The speaker seems in pretty good shape. There is no voice coil rub against the core by gently and evenly depressing
the outer edges of the cone. Maybe it is still the speaker or possibly the audio outputs?

A couple more points to ask about ... when finding a distant station that is near the extreme low end of the
AM band, the radio has a varying howl / whistle background sound with the station. So you have to very carefully
try to minimize it or chose the "interference" you can tolerate, by very slightly moving the selector knob.

Question about the "square box" antenna structure that is inside and around the record player. It will rotate
a few degrees inside the limits of the cabinet but I hear little or no change in reception. Wondering what the idea of
this was since there seems to be little or no value (that I'm aware of anyway) and how was one supposed to access
or manipulate this? ... Just by reaching in thru the record player area and getting a hold of it and moving it?

Thanks again for any help,
Harlan Icon_biggrin
