All correct notes, wet/dry, 85/105 degrees, etc.
Here are my observations, and of course, some subjective observations may vary:
1. the caps are indeed 105's
2. Hours rating on these ??? What I do tell customers and recommend is a re-capping of every 7-10 years, which, obviously, can vary wildly as far as hours p[layed are concerned....yet, I'll do this pretty much close at cost, starting at $ 50. with a free complete tune-up included !!!!!
3. As for break-in, man, I'd be soooo happy if that wouldn't be the case. Kind of awkward to say hey, congrats to your new amp, guess what, it'll be months for it to sound best....BUT it is true, and I have to be upfront about it...just me, have to.
4. Rule of thumb, every single component, solder joint, etc. would need at least 200 hours to fully break in.....not scientific, just earific.
5. Yes, absolutely, leave the suckers on. I'd do that with every single component, except some tubes, obviously, and unless the manufacturer specifically tells you not to do so, obviouslier.....
6. Consumption is very low on leaving the amps on, figure appr. $ 3-5 / month, depending on where you live.
That's just my take of it, based on a couple of hours of my own experience....
Late,
