My schematic shows 33pf. The parts list shows 39pf. Looks like it is across the 20pf. Trimmer cap for the 8999.3khz crystal.?

The IF board schematic shows C428 present next to the CW Oscillator crystal and trimmer. Schematic shows a 39pF, but the cap I removed had 33K stamped on it.?

The C428 is 39p.

I followed this helpful blog, I removed C428 and was able to get 100+ Watts of CW output on my FT-301D. Note: ?After removing C428 from the IF board, it tested 19.8uF on my B&K capacitor check. It is supposed to be 33uF +/- 10%. It has aged but lost value. Before removing C428, I was getting about 5W tune power on 10m, 15W on 15m, 35W on 20m, 30W on 40m and 25W on 75m. Peak SSB power is around 150W all bands.?
