N_Cook <diverse@tcp.co.uk>: Nov 23 01:59PM Mackie ProFX12 , a couple of years old. OK at soundcheck, but failed in first use proper. Owner retained one XLR feed and used a 1/4 inch line for the other channel and continued. With me checks out fine. Now the double XLR boards has that style of soldering , pin and cup?, where the end of the pin is enveloped in solder. Then as 4 closely spaced pins for the XLR difficult to check by flexing. Will try tomorrow with proper continuity check on all pins. I've seen this failure before , but I don't think with proper solder. Does PbF expand on cooling and so the cup helps to break contact, more than just a ring of solder, or just cold-solder joint failuredue to thick + long pins so substantial heatsinking. At the moment no sign of any solder sweated thru the presumably plated holes to the component side of the pcb, "nice" clean gold finish, suggestive of inadequate heating at soldering. Hopefully a pbf problem on that rear board and not balanced line feed buffer amp failure , requires removing all the top panel hardware.

Lead-free solder does not flex. It fractures. Lead based solder will flex because of the lead.   Paul

Any ideas?   If you want people to help you you have to make it easy for them. Dimensions? Profile? Do you expect them to take apart their old Signature to know what you are talking about? CP

Any ideas?   Model airplane spark plug?   You probably won't find a cheap solution. And the penalty for failure might be death of the cook.

mroberds@att.net: Nov 23 07:11AM > A ceramic insulator that supports the heating element in our old > waffle iron broke. Any ideas?   Keystone Electronics has threaded ceramic spacers in 1/4", 3/8", 1/2", and 3/4" outside diameters, with either 6-32 or 1/4-20 threads. Digi-Key and Mouser stock some of them in small quantities - roughly $3 to $6 or so, quantity 1.   http://www.keyelco.com/category.cfm/Standoffs-Round-Ceramic/Commercial-Ceramic-Threaded-Standoffs/p/506/id/1078   McMaster-Carr sells ceramic bars, sheets, rods, etc, but they can be uncheap. You'd also have to cut or machine them into what you want, which may be non-trivial.   http://www.mcmaster.com/#Ceramic-Sheets http://www.mcmaster.com/#Standard-Ceramic-Rods http://www.mcmaster.com/#Ceramic-Hollow-Rods   You might be able to find something that would work inside a similar heating appliance, from the thrift store or equal.   Standard disclaimers apply: I don't get money or other consideration from any companies mentioned.   Matt Roberds

I read it as "today, whatever radio station I'm listening to, it only comes from the left channel".   Sorry :-)   -- Husk kørelys bagpå, hvis din bilfabrikant har taget den idiotiske beslutning at undlade det.
