1.5k spurs

A friend over seas has An MCHF that all of a sudden started having 1.5kz spurs above and below set frequency.
Removing C78 has no effect. Disabling the PA has no effect.
Any ideas friends?

Spurs in receive or transmit mode? Details in the studio, here is not a literary salon.

Hello Friends!!
I don't know what the "Salon" is!!
But at any rate, I have solved the issue here.
I have this radio on the bench now and I discovered a torn trace going to C7a.
Repaired the trace and all seem well.
De Chuck, 73
Have a great day!!
