Could you point me to an extractor tool and/or housing online? I have looked online but have no idea what these connector/housing are called. Thank you.

Edit... found them. Molex connectors

If the 'crimp' problem is where the wire meets the pin, drop a small ball of solder on it.

This has been such a crazed issue. Here is the latest. I was able to crimp the cable inside the molex connector with small needle nose pliers. I also found that the return positive connector in the reverb pan needed to be snugged up. Prior to this point I would sometimes have an open path on the return cable.

Now I am reading 185 ohms consistent on the return across all junctions (there are multiple connections from the pan to the board including 3 molex junctions). I am reading 190 ohms on the send side.

At this juncture, with the tank resting outside the amp cabinet I have perfect sounding reverb and no noise.

As soon as I move the tank inside the cabinet I have a variety of issues including hum, hiss, loud crackling noises, and no reverb. This is all tied to the reverb circuit. If the reverb pot is at zero there are no noises.

The return output sits in the diagonal corner from the power supply.

If I move the return cable around I can generate more crackling noise.

That tells me that you are still having issues with the cabling.

I would agree. Taking it to work tomorrow to see if we may have an extraction tool.

Without hearing it I can't say that this is your problem, but some shielded cable can act like a capacitance pickup and will make noise when flexed or jostled.

yes it can, but it shouldn't intermit.

These are the Molex 09 series of connectors. The white nylon plastic part is the housing, the crimp pins are on the wire ends and snap into the holes on the housing. I have had perfectly fine results with a cheap waldom crimp tool, should cost under $20. Do a search for molex extractor tool, and they should come up.

If you are putting new pins on cable, you can add a dot of solder for reliability, though I trust the crimps myself. But you still need to crimp the pins because otherwise they don;t fit into the housing. You can buy pins and housings loose, but Mouser and others also sell little kits, wwhich have a housing or two and a handfull of pins - just enough for a project.

There are a lot of different connectors, and a lot of different extractors, you would need the one specifically for the 09 series. I use this one:

Working now with no noise.

In the end it was a series of bad connections in the cabling and in the reverb tank. I think the worst part was the green return wire at the transducer was hanging by a thread. The tank would only work upside down.
