Replaced Sansui 5000a (5) main caps, left channel out on speakers only

Just replaced the (5) main caps (C004,5,6 and 7, C013) and the sound is bold/great thru the headphones, both channels work great. But...no sound out of the left channel on the speakers. Double checked the speaker connections all around and the speakers as well. Maybe a bad solder joint? Not sure, any suggestion on which cap may be the issue?

Before the cap update, the speakers L/R worked great...of course!

The main caps are 3300UF, 100V. C013 was 2200VF, 100V.

Thanks in advance!

Check to see if the left channel doesn't work in all A, B, and C connections.
Since the headphones work then both left and right channels are working good up to the speaker switches.

Problem is the signal isn't getting out of the speaker switches to the speaker connectors. The signal needs to be checked from the red dots through the switches to the speaker connections.

Thanks for your response.

I checked the A, B and C connections and the same problem...but...after 3-4 additional Deoxit soakings/30+ dial turns on the speaker selection switch and re-soldering a few suspect connections on the main caps and speaker "B" connections, both channels work fine now.

One interesting note-even right after turning off the receiver, I get a little static thru the speaker when hooking "left" negative/ground wire on A, B and C speakers connections. Strange, maybe a grounding problem somewhere?

Cheers, now I can hook up my newly completed HIVI-Swan diy 3.1a speakers!
