Left side volume lower for FM only

Hi.
I just recapped a Marntz 2325. Everything is working great except that in FM mode the left side volume is very low compared to the right side. Here are the specs of the issue:
*The Dolby levels controls will compensate when using Dolby
*The issue occurs only on FM. The other modes work perfectly including AM
*When switching the "Mode" knob to reverse, the issue follows to the other side ie the rt side is lower
*When the "Mode" knob is set to mono both sides are equal & @ the proper volume

Do you think I have an adjustment problem or component issue?
This is my first rebuild. I basically started this project with good soldering skills & a limited knowledge base of electronics so please be patient with me.
Thanks in advance for your help,
Phil
 
I assume you had to disconnect the mpx board to recap it ==>
Double check that the output pins are connected properly
311 and 313 if remember correctly

Thanks Robin. I just checked those connections as well as where they connect to the multi selector & everything there is good. I'm amusing that I've broken a wire somewhere before the dolby board. I can boost the signal with the dolby level adjustment but now the FM volume is weaker. I think it's gotten worse since I've been back in the unit.
