FYI, facing the back of preamp, the correct direction of HiFi Tuning Supreme fuse is left to right. In the other direction, sound like out of phase.

Several members and I exchanged notes and we heard the same. It was also confirmed by Kevin Hayes.

Congrats on your VAC SigMKIIa. I have the same pre and like to offer some suggestions.

1. The pre runs very hot so have you consider getting open rack?
2. The pre is very sensitive to tube rolling. Many Agon members have the same pre so search the threads for info.
3. Replace stock fuse with after market. I'm using a HiFi Tuning Supreme. Direction matters ... this is the 1st component I can easily pick out the direction. Again search the threads for more info.
