Thanks for offering this item at such a good price. Proved handy in identifying the part I was looking for my set.
Thanks again.

2. Turned Power switch on. 3. Put the disc (YEDS-18) in to play the number five track. Confirm that reading on frequency counter is 4.3218MHz.
8. Press the REPEAT button. (The tracking servo and sledding servo are turned ON.) Confirm the C (DC voltage) is almost equal to the A (DC voltage) is step 7.
