[ARC5] R-10 in the receivers.

[J Mcvey via ARC5]

The circuit requires a 50K pot to ground, so perhaps it was to maintain the max cathode voltage a certain voltage. That voltage would be approx (50/400)* 250V = 31.25V. Does that make any sense?  I have no "off the top of my head" knowlege of the operating curves of those tubes, as all of this was way before my time.

A friend who is working on is first BC-453, which was murderfied before he 
got it, and which he is trying to get back in operation, has called my attention 
to R-10, a 360K 1/2 watt resistor which is connected between the 
gain-control line and B+.

The table of replaceable parts describes that resistor as, "H.V. Bleeder to 
Gain Control."

I am somewhat mystified concerning its true purpose.

Can anyone enlighten both of us?
