Snow removal and ice have occupied much of my time so I thought to look to the Egyptians for their wisdom.
I present you with a substantial amount of 80% nickel for a 10-10-300B amp.
I'll admit that full bandwidth 80% nickel IT's and OT's are a bit above the mark but I have to say I was so pained to take the OT's out of circuit after the listening test that I had to do another pair to replace them.
Unfortunately the 80% 300B outputs are only good for an honest 3-4W@50hz and that is what brought up the mini-pyramid approach for a 15W full range 304TL on 49% cores.
