A friend is looking for an entry level tube amp. I suggested the A10 as it's a lot cheaper than the A12 and is easily modded to run 12AX7s by rewiring the tube sockets anyway. A 10min job really, which I said I do for him. I also offered to do Skunkie's mods if he wanted to go that far, but I suggested he live with it for a while to get used to what it sounds like. (I had an early iteration of the SoundArtist, ie. SA34A, which was basically an A12 version that came out a few years before the Reisong A12. It was a sweet amp)
Anyway, he calls me and asks me what version of A10 to buy, saying that the P2P version has a couple of transformer options available. When I looked, he was right! Both A10 and A12 have options for "upgraded" transformers. Have Reisong updated the transformers in their "upgraded" A10 and A12 models?
