& yes, the selector switch is completly removed (also the ground wire now....) - did not help
Indeed, it can get tiresome like this.
@Avance Concrete Fan can you give us a photo from below the board as well? More detailed/sharp the better.

Hi guys,
Sorry for the hold-up. Actual work came in the way...... I have gone through the component lists and the placements on the board 4 times and find nothing wrong. I have also touched-up all solderings. To me they look good. Still it doesn't play on the right channel and I have ZERO idea why. Any suggestions for a next step?

It looks to me that the filament is now broken.
Picture from post #8,869 shows a good filament. Picture from post #8,905 shows what looks to me to be a broken filament.

That's about the only way to prove it to me since these filaments are so very fine, and the second photo just doesn't quite the resolution that I would want. In the second photo, I can see neither filament, and we know that the two filaments are attached in the center. Light 'em up!
I am very happy that I am wrong. The filament looks good. 🙂
Please post pictures that show the board with all of the wiring and jacks.
And please let us know exactly what works and doesn't work.
Also confirm that the voltages at the Test Points are as they should be , or not.

Glad the filament is still intact. ACF...what I was suggesting is that the particular interaction between the B1K and the amp you are using may be strange , not that the amp doesn't work properly. If you have another functioning amp try the B1K with the second amp and see if the channel issue still exists.
when both out RCAs on the preamp are connected only one speaker plays, then when I disconnect the Left RCA cable then the working speaker stops playing and sound appears in the other speaker (which did not play before).
In previous post we tryed to remove the input selector but which did not help. The pictured volume potentiometer is also a second one tested.
I will test with different am later during the week.

Swap left and right rca positions with ic cables. And try. If it sound comes to the same side speaker as with non swapped rca, it is an amp issue.
not sure I completly understand, but I have swapped the cables between the connectors, and also used completly different cables. It does not seem to be a cable thing if this is what you suggest?
Swap channels is what i'm saying, on your preamp connectors put right to left, and left to right cables. So your left channel will connect to right channel on amp, and right channel will connect to left channel on amp. Play music. See if the same speaker plays as with regularly connected.
So it is an amplifier issue since it is the same. Do you have any other preamp or source to connect directly (that you can attenuate)?
I think that we are having a problem with semantics here, or 'I thought you meant when you said' type of thing. Seems over the top, but it is the reason that I have to be very specific i.e. for example, when you say cables were changed, do you really mean channels? Or cables were swapped (I read substituted with new cables), do you really mean channels? And so on it goes.
Some of what is being discussed has already been tried previously in the thread before. This is why things can get frustrating. FWIW, I have had a similar problem in the past with a B1K, and so that leads me to believe that this problem is with the B1K.
