Here are the results of my voltage test:
Terminal = VDC
1 = 90v
2 = 200v
3 = 0v
4 = 200v
5 = 85v
6 = 0v
7 = 120v
8 = 0v
9 = 115v
10 = 0v
Both LEDs are on.
No smoke, no crackling sounds, no sparks.
As I write this I am listening to a song by Dream Theater titled "our new world".
I'm driving the amp with a Fiio V1, and listening on a pair of Beyerdynamic DT770s - 250 ohm model
Fiio output at max.
With the volume pot at 1/2, the listening level is very nice!
I can't crank it up to 3/4, as it gets uncomfortably loud there.
But this is absolutely wonderful.
I think I'll spend the rest of my new year's eve listening to my collection, and maybe even rolling a few tubes I have prepared just for this occasion...
Thank you kindly for your help!
