Hello All, I recently bought a Fine Corsair 11. Upon power-up the PTO drift 3 Khz! for the first 15 minutes and the drifts down 3.5 Khz for the next 2 Hrs. It doesn't seem to be a PTO rebuild problem, after 3 hours on the PTO is very stable and has a minimum of wooble. Any suggestions?? Best to All & 73 Bill Marvin KB9IV
