[Boatanchors] BC-453A tuning knob

[Glen Zook]

There are a number of different possibilities for a tuning knob.  One of the easiest solutions is to use a plastic knob from a broadcast receiver.  There are quite a number of these knobs that have a shaft with an internal diameter that fits the splines in the BC-453.


Another is to use a short piece of copper tubing that will "force fit" onto the splines and then a "normal" knob can be put on the copper tubing.

I bought a BC-453 off ebay to add to my boatanchor collection. I have a
power supply (alternative use:  to power a WWII Iconoscope TV camera).
I don't have it yet.

The plugs are readily available. But the tuning knob seems to bve a strange spline thing.
As best as I can tell a ARC 6743 knob will fit, at least to an extremely similar radio.

one is shown here on a different radio

Do these exist? Can they easily be replaced with something else?

If not, it sure looks to me that its going to be a very machine shop job.
