Philco Model 16B Cathedral
#25

Chris

When I asked you earlier about the volume control circuit, if it was hacked, you said the audio circuit (I thought this is how you referred to the volume control) appeared to be stock.
If it were stock, I would not touch it as, as I noted before, there are mods to it reflected in the notes.

One of them is, when the volume pot top pin (input, coming from the detector) is connected via a capacitor, while the pot itself is higher value than shown in the sch.
The detector output is loaded with a resistor before that capacitor.

Make sure you find the appropriate circuit sch before you touch it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
