Tempest preamp DC offset and channel balance
« on: 27 Jun 2017, 02:29 pm »
Hello
I have purchased the Tempest preamp from Klaus a couple of months ago and have been enjoying it ever since. The preamp is mated to the Stratos amp. Great sound.
Recently using a multi meter I measured the DC offset and channel balance at its L & R output. The DC was around 0.1 mv and the right channel output is greater than the left.
Could this be the reason since I was not quite happy with the center image.
Anyway looking at the PCB inside there are 2 blue trimpots near the output stage of this preamp. I read somewhere that these 2 trimpots can be used to adjust the above.
Without having the proper instruction I do not want to touch it.
Request to Klaus or any members of this forum if they know how to adjust and have the instruction handy. It would be very helpful.
Thanks
