I just finished up my build of the DripOpto LA2A, and everything went pretty well, once I chased down the problem with the stereo adjust pot (short in the cabling causing no compression to happen).
The unit is pretty quiet over all. I can't really hear much in the way of hum, just electrical noise down low.
One thing that I'm not too sure of is the bouncing noise floor.
Using a LYNX Two card to monitor the noise floor, I can see it bouncing (no signal applied) between -72 and -66 or so. This happens whether it is connected to a preamp or not.
My first guess would be the 12BH7, but that's just because I like to blame tubes that I know nothing about.
Anyone else have this issue, or any suggestions on easing my bouncing noise floor?
Thanks...
