Hello Mike,
This rf gain control pot is 1660 ohm, with a tap at 400 ohm. Replacement by a wire-wound pot withhout the tap is possible, at the price of a less smoother volume control.
An alternative is a linear carbon-type pot of 10 Kohm with a parallel resistor of 1800 ohm/2 Watt.
>Hi. Does anyone have spare parts for the Philips 834A valve radio, which was made in 1933 ?
>My requirements are a replacement wirewound volume control(r.f gain).At present, my control is open circuit in many places, and not easy to repair/rewind.Can anyone suggest an alternative method of control replacement,through repairs experience on this radio ?
>I also require a replacement back panel for the receiver.
