Final Assembly. Its not perfect but turned out nice for something created, mostly after bedtime, or during nap time, over two months. The final configuration is is the same input and driver tubes but feeding KT150 and Lundahl transformers air gapped closer to the idle current I was able to achieve...approximately 33% higher than design, which yielded about the same wattage increase to mind altering 4W.

As I may have mentioned in another thread, I don't understand how this amp can now drive my main speakers at 85dB sensitivity. This has turned out to be a very very capable amp. While I only grasp the concept of a cathode follower output stage, I have to think it has something to do with the current drive available with these output tubes; as they don't provide any voltage gain.

The bottom end of this amp is staggering, listening to Fleetwood Mac's Chains...the wall I was facing seemed to have turned into the skin of the kick drum during the intro. Fantastic channel separation and depth, the one item my OTL amp holds over this amp is instrument separation while both do this well, the OTL (which is push pull) has unbelievable space between as if to amplify the "nothing" where it is supposed to be as well. My OTL is anemic with the low frequencies for my main system load...but is dead quite so naturally should be coupled with high efficiency speakers (one day when I have more space).

Thanks so much for sharing I always appreciate people sharing these builds and it is good to hear that you are enjoying the fruits of your labour
