After posting yesterday I contacted Roy and asked some question about the Octal PCB and the Auto-Bias PCB. I decided to pick up an Octal PCB and do some upgrades like I did with the original pcb and some that I didn't do that came with the kit. This should be a nice improvement in sound. I will post some pics of what I do over on Tube/Diy and on AK when I'm finished.

Airtime and I have long been curious how much improvement would be gained by 6SN7s used as the phase inverters, over the two 12AU7s.

I've thought about converting my phase inverters to 12AT7s (VTA's original configuration) since the 12AT7 is a slightly more linear tube than the 12AU7, but I suspect that your all octal upgrade is really the way to go.

I look forward to the updates and pictures.
