Ok.
Was excited to try some music
I switch the crack + SB on.
After about 6 seconds the 6080 lights up blueish before it lights as usual(wires in reddish light) after about 10 seconds, when a humming starts (about 80-85 Hz like a ground loop?)that is first noticabe on the left, then also on the right channel although slightly weaker. This humming gets considerably louder up to 20 seconds. On a cold amp it wears out at about 60 seconds. Faster on hot amp, maybe 15 seconds after it gets loud.
From then on it is quiet until I turn the volume all the way down which makes the noise on both channels with max noise. When I turn the volume all the way up to 100% it is also noise with left>right. In between it is quiet
If I attach a source, there is only a slight hum which gets louder from about 70% volume to 100%. Ig I turn volume all the way down, the noise is back to max binaurally.
In between, as in 0%<,>100% the Sound quality seems sweet, but it is overshadowed by the other issues...
Again I ask for help. And of course, here are the voltages witj SB installed:
1. 73,4 v
2. 173,45 v
3. 0 v
4. 173,41 v
5. 76,8 v
6. 0 v
7. 101,86
8. 0 v
9. 102,8 v
10. 0 v
11. 0 v
12. 0 v
13. 173,1 v
14. 0 v
15. 192,33 v
16. 0v
17. 0 v
18. 87 v
19. 82,7 v
20. 0 v
21. 211,4 v
Hope this can be resolved.
Yours truly
