Congratulations, Jack!??Persistence pays off.??
When checking the voltage spec on the capacitors, remember that the scope is measuring peak to peak, so the capacitor rating needs to be greater than 1/2 of this value.? You may want to replace the discs with COG parts at some point, though I believe an LPF filter is not as critical as other uses.??
Most disc caps are rated for 50 volts so they may be over-stressed.? Many 100 volts and higher SMD in various sizes and values are available on Mouser.??
I would also break out the TinySA Ultra to check for signal purity before returning to the air.
