- My 160m/80m/40m/20m amp design calls for a 250pF Ctune and 1500pF Cload. I notice some designs use capacitors with the full capacitance range variables, while others use lower-value variables and fix

- Hi Steve, I try to use full range variable caps whenever possible. Padding both C tune and C load variables does work, however I have noticed that given the same capacitance either way changes things

- I agree a vacuum variable is the better solution. Another possibility is to use two dissimilar caps ganged together. In your case, say a 100pf and a 150pf. You use them in parallel for 160m, the 150p
