As a small minimod mod, I have experimented with a tiny twin gang cap, about 20pf per side, in parallel across the two main (270pf) caps, but reduced those to 220pf. This allows a small swing, about 30kHz, just enough to get rid of birdies and interference on some sets. I’ll report back once I’ve used it for a bit.
The cap was NOS but was probably designed for a small vhf only set. Nice metal framed air spaced job, with a built-in 3:1 drive. Only about 20mm across.
