Christ, yet another glorious fart of ignorance (and I eat a lot of Mexican food, so the aroma won't be coming out as Kim Kardashian's next fragrance — or will it? "New!, from the dumbest twat on Earth — Eau De Roach Coach Tijuana — now available at a Flea Market near you."?). For the relay connections J1-3 and J2-3, do I run 2 ground wires for the speaker leads from the capacitor bus bar? Or am I completely missing the point here?

Broken beyond repair but highly affable
Oh there are worse...Yahoo comes up with one every day.

Yes, one for each channel...

Other than connecting the meters, I think I'm ready to put some juice to this thing. However, I spent all day with a magnifying glass in my hand going over everything I can still see. I've been unable to see anything amiss, but if any of you do, please let me know. I think I'm gonna take tomorrow and just look all day again. Other than the really messy hot glue for the meter lights, I think it came out okay. The glue gun wasn't working properly, and I wanted to make sure there was enough on there to hold the sockets, even when replacing fuse bulbs, so it got pretty sloppy. But it will all be out of sight soon. Now I just hope it works properly. Thanks, everyone, for the help and support. And thanks especially to Joe for his enormous contribution to the community, as well as to myself.

Oh yeah, also, I put a new cord on the unit but didn't hook the ground wire to anything. You can see it up by the fuses. Obviously, it's the green one up there. What's the consensus, hook to something (what?), or clip it off?

I double and triple checked everything, then double-checked my dim bulb tester, just to be thorough, using another old beater amp. With the Sony amp, the tester worked as expected, and after the initial bright flash from the bulb, it just kind of glowed for as long as I left the whole system on. So then I plugged in the WOPL amp and everything went as expected, except the bulb didn't glow, and just went out. Also, the relay never clicked. This was the first time bringing the amp and relay up. The only other testing was with the backplane transistor install. This time, as with the last, nothing unusual happened. No smoke. No odor. No crackling noise. Nothing. So that's the good news. Nothing catastrophic occurred. I was going to mess with it, but thought it would be better to seek some advice as to where to do some voltage testing. The fact that the relay isn't clicking is what's making me think something may be amiss. But also the way the bulb went completely out after the first bright pop, like it immediately stopped drawing current, and it was unlike what the other amp did when I tested it. Any advice as to how to proceed. Or should I just start making random voltage tests as see if everything is getting power? I'll get after it again tomorrow, after I go get some propane for my heater. It's gotten cold here and I ran out of fuel.

Yeah, like I said, it flashes, but then goes completely dark. And if I turn the Variac on and off, it doesn't flash again. The bulb stays dark. But if I shut the whole thing down and wait a minute, the cycle repeats itself. It'll flash again, then go dark.

No outputs in? Backplane fuse ok? 15 volt source ok?
It's just sitting there on the bench, nothing hooked to it. And I assume all fuses are okay, since it will recycle each time I start over. 15 volt source? Where would I check that?
