Hi there,
I'm a relative newbie to electronics, but this problem is extra weird.
It's a hamptone jfet kit, finished, and sounding great except for no phantom on the right channel. Here are some observations so far:
1. There's only 40.3 volts when the switch is engaged. When the switch is out it's 48.0.
2. Tried swapping the switch out with another, but the same deal.
3. The supply is delivering a handsome 48v.
3. On the good channel, I'm getting 48v on pads 1-4 of the input transformer (wired 1:8).
4. On the bad channel, I"m getting 32 (or so) volts on the amp side of the 6.8k resistors, but NOTHING on the other side of them.
5. I tested all resistors.
6. This sucks...I thought I did such a good job this time.
:green:
Mainly, I'm kind of hoping somebody's seen this "switched-in" drop in voltage.
Thanks so so much,
kelly
