All the phono tubes are present. The 12AU7s that I ordered finally arrived. The two tubes nearest the front to the right in th P2 were filled with 12AT7s ( the third tube behind these was a 12AU7. I was mistaken when I said it was a 12AT7). I replaced these 2 12AT7s with the new 12AU7s and the gain on the line stage dropped significantly. Gain on the line and phono stages are now more equivalent, in fact, the phono is a little hotter.

Turns out a friend has a tube tester that I can use, saves me having to buy one.
