Adjust L1001 on the PBT/Reference board to put the 40 mhz oscillator back on frequency. The 40 Mhz oscillator provides the 500 khz reference for the DR7 board. the 40 mhz crystal tends to drift more than the other two crystals on the PBT/Reference board.

My TR-7 digital readout is off by 100 hz. Can anyone tell me how to correct it?
