Hi and welcome to Beoworld!ย The BC9500 is a great first purchase.
First thing to check is simple:ย Are you sure that there isn’t a 3.5mm to 1/4 inch adaptor in the headphone socket?ย Sounds silly but this mistake has been made many times in the past!
EDIT:ย But if the headphone output has the same problem this is unlikely – apologies!

BRONZE MemberThanks!ย It really is beautiful.ย I saw it at the estate sale with a matching Beogram 9500 and had to have it. (Even though it was completely unneeded.ย LOL)
No adapter installed.ย I used a 1/4 inch plug to test my headphones.ย But I appreciate simple troubleshooting before tearing into a unit.
30 August 2024 at 17:13 #58728BRONZE MemberThe muting relay is a likely suspect (trigger it on/off several times to see if there is any improvement).
Check if the “dummy plug” is installed in the LINE IN/OUT on the rear connections panel (if removed, the pre-amp signal won’t be going to the main amp, although this wouldn’t explain the partly working secondary speaker output…).
Also check the BALANCE adjustment.

BRONZE MemberI triggered the “Mute” a few times, I didn’t hear any clicks of a relay activating.ย As far as the Line In/Out plug, it is installed.
The Balance seems to operate correctly.
Thanks for the response.

BRONZE MemberUpdate: New relay at R1 installed and no change.ย Main L+R passive, no audio.ย Secondary R is good.ย L is weak.
Any ideas from experienced B and O techs?

BRONZE MemberUpdate:
Replaced TR22 and now the mains have audio.ย Main and Secondary Right Channel is GOOD.ย ย Main and Secondary Left channel is WEAK.
I am leaning towards an STK module.ย Do these regularly go bad?
Thanks!
