Marantz 2270 P500 Board

JBL & marantz
Working on a fellow AK members 2270. The FM Tuning is fixed at the 8:00 position with or without a signal. Signal strength is within the 4th section of the Signal Strength area. Stereo light is not on. The Stereo light works for all other functions (except AM).
According to the Service manual I downloaded from Hifi Engine, the adjustment for the FM TUNING meter is located on the P500 board.
The manual shows this board on the top of the 2270. When I removed the metal shield, the component designation is not that of the '500' components.
Anyone know where the P500 board is located?

Thanks

Marantz 2270
Serial NO. 3352

Never mind. My mistake. I missed the board opposite the Gyro. Removed the shield and there it was.

tBuckner,
Thank you.
Didn't realize the photo was upside down. Was looking at the wrong PCB. In combination with the ST 1000A FM Alignment Generator, a simple adjustment of L501 got the FM Tuning meter back in operation.
The next issue is the Stereo light fails to light in Stereo. Works in all other functions except AM. I'll check the 2270s FM output on the scope later today.

The latest PET (12/8/14) scan was very encouraging. The suspicious areas from the first PET all showed improvement. No mention of recurrence in the scalp tumor site as well.
Chemo this round (Round 6) was difficult, but necessary. My Oncologist gave me a few months off of Chemo. Next round sometime in March. PET scan again in April.

Keeping Sarge in mind.

Ron
