FT-1000, serial OG060181 (1990 ?)

Problem and symptom:

 Sudden 300 Hz jump up in frequency both on transmit and main receiver

reception, CW and SSB, LSB and USB. Audible change in passband sound.

Happens 10 to 20 minutes after switch-on and usually returns to initial

frequency after a few seconds or a minute. Repeats are not uncommon.

Seldom noticeable after warm-up. Does not prevent operating, but is a

nuisance. PLL unit has been replaced to no avail. The rig is certainly

old, but I have grown accustomed to its performance in other respects.

Any correcting suggestions?
