The reading of 399 ohms which I will assume was on pin 8, ( you listed pin 7 twice ), is of very little concern, for its common to all Y amps, and comes from R205, and is in tol.

What should be of concern is if the resistance readings for pins 7 on V25/V24 are noticeably different, if they are, then BOTH the 68 ohms resistors should be replaced with a closely matched pair.

I just measured pin 7 on both one is 78 and 79 ohms
