Model 41-296
#7

Brenda and John,

First, thanks for the ideas, etc. The old cap has lost dot one, however by the looks of it, it's orange. I have attached an image of it, however I'm not certain which way to read this since I really can't determine what is top or bottom. I can only assume the NY USA imprint reading upright would be correct, but not certain. This cap measures about 2500pf, or a little more. Based on the inductance range of about 30 to 58 uH I've measured, 30 being with the slug in all the way and 58 out all the way, 3000pf would tune 455kcs. The old cap did however seem to produce a sharper peak than the 3000pf I have in there now. Maybe because it was off, or possibly leaky. When adjusting the slug now, it's hard to tell where the peak is. It does have effect, but very broad. Maybe it's designed that way.

Thanks again for the thoughts. I think I will leave the 3000pf in there until I get further into this rig, or hear it's the wrong value.
