Justin will a 12AU7 work as well with a Kenzie? I already have an adaptor and I could use more range on the volume pot I max out at 9 AM. If so do you have a recommended 12AU7 you like for the Kenzie, I will give it a try. I have lately been using an RCA grey glass 12SL7GT but am always looking forward to trying new tubes. I was lucky to find a stash of Tung Sol 1626s that should last me for a few years.
