Help! I have a nice Titan - works great for the most part even with a 20 year old tube... however on 10 meters the "peak" on the tune capacitor is right at the minimum capacitance point above about 2

I have seen this as well with the two Titan 425's I have. Seeing a fix here would be great! I love the amp....but would love to see the tuning more in the "mid-range" of the tune sweep. Thanks... Ric

A "fix" has been shown for many years in the ARRL Handbook, and others. You install a small inductor between the plate block capacitor and the tune capacitor. The problem is that some "bread-slicer"

You don't want to be physically modifying by adding coils. The fix could be to bend the 10 meter section only of the tank coil slightly. It should only take 1/4". For instance the difference between

Spread the turns very slightly in the section of the tank coil for ten meters. You DO want the plate capacitor at nearly minimum C. Nonsense. That's totally false. It can't happen. Series resonance

Thanks Tom... this makes perfect sense to me. Indeed adding an inductor may accomplish the one result - but at the risk of adding a "hinge" point or place were there could be additional non-accounted
