38-9 bullet - how bad is too bad?
#6

Progress update... recapped and one resistor changed (the big 3W 10k beast which was well out)... I may have to change a couple of others as well but I'll see how the voltages look when I bring it up.

   

I've also found a grommet that when cut in half seems to hold things quite nicely... so while not pretty, it's probably what I'll go with, at least for now.

   

And I'm now bathing the topside in rust remover after giving it a vigorous rub-down with a small wire brush...

   

I'll probably need to repeat that process several times at least... hopefully it will come up to the point where I can live with it... it's not going to win any beauty contests thats for sure.

   

The only question I have at this point is the tone tap on the volume control. In the original layout (using Philco caps, so I don't think it's ever been changed), the tap connects to the wiper via a 51k resistor and a 0.006uF cap

   

But the circuit shows it from the tap to ground - which is where I have wired it. Any thoughts on the difference?

   

Cheers, Steve

There are no personal problems that can't be overcome with the liberal application of high explosives
