I can't help feeling this is kind of lame, but I haven't been able to figure it out, so here goes....
I finished one of Bruce's 5E3 clones last week. No worky. The power comes on, pilot light lit, tubes glow, but no sound (and thankfully, no smoke). Not a crackle or pop. I was very careful putting the amp together and checked everything carefully as I went. My only question as I was building it was, "why the switching jack for the speaker?" But I figured "whatever" and preceeded to connect the black wire from the OT to the ground terminal on the jack and the green wire to the tip terminal. I left the middle terminal (switching terminal) empty.
So, when the amp didn't give me any sound, the first thing I thought of was the speaker jack. Checking for continuity with my VOM, I've found that the ground and tip terminals are both common with ground. I'm sort of baffled. I'm wondering if any of you have seen this sort of thing, and just for interest, why the switching jack on the primary speaker input? Many thanks.
