Now, we know where the test points , are actually wired to, i feel unsafe to use alligator clips to take measurements, just worried of a short.
And i have people moving in and around my place, when i start to work on it, just in case they move the wires around or it shakes a bit, the results are going to be drastic.
Have ordered these from ebay.in, and am waiting for them to reach my place.
Probably this is the only amp which i am going to take 30 minutes for biasing.
Once they reach my place, i will take the bias measurements and post them here, hopefully it is a fits into the male test point pins.
Meanwhile there are couple of other points which i wanted to post , regarding the preamp section.
1. The outputs from tape 1 & tape 2 recording terminals, are at a fixed voltage, meaning the variance in big preamp knob has no impact on the pre outs for tape 1 and tape 2 rec.
2. The more interesting part is that when you have source connected to AUX, and then check the pre amp outputs jacks in the back of the amplifier, there is no voltage produced, rather say the signal is absent.
The only way to enable the signal at the pre amp outputs 1 & 2 is to change the amplifier mode from (Integrated to 1 or 2), this disables speaker outputs from the X11.
So if you need the amplified speaker outputs from the X11, and also the preamp outputs from the X11, the only way to do this will be to loop the connections from preamp outputs 1 to external power amp inputs 1. ( i haven't tried this yet, but this is just my understanding )
Or in case you have an external analog eq, the preamp outs from the X11 to analog eq, outputs from analog eq to external power amp input 1.
Many of you might already know this , but i have just added this to my thread to keep track on some basic tests, please ignore if not relevant.
