 Duster,

Wondering if you might be able to help me solve a small mystery. I have a friend who does some amp building in his spare time and he's taken to using Oyaide FTL-PP Solderless Terminals and their IEC inlets on his amps. He's been having a bear of a time finding the proper/correct crimping tool for the job. Any experience or words of wisdom you might pass along on that topic?

Thanks,

Mike

 Alan,

Thank you so much for fielding that call. I'm sure my pal Mike appreciated your help. Wasn't sure who else to turn to. It was on my recco that he's using the Oyaide parts, so I felt obliged to try to help him out.

Again, thank you.

Mike

 I'm glad you found what you were seeking. Perhaps you can share the solution with the forum for future reference.

 I spoke with my friend who spoke with Alan, and it seems the answer was to use needle-nose pliers. I guess my friend, Mike, had latched onto some additional info from a different source which indicated that a Faston 250 is the correct tool. Unfortunately, as I understand it, there are many different tools in the Faston 250 family and the source did not specify exactly which one was required.

Addendum: It appears that the Oyaide connectors are like Faston p/n 41829-1. Faston is a brand manufactured by TE Connectivity. According to TE Conn, the proper tool is their p/n 90120. The bad news is the price tag of one is WAY beyond the price any normal person might consider paying. Digi-key wants $912 for one, although I think they'll throw in free shipping ...

 I primarily suggested soldering the Audience OHNO wiring directly (twist the strands, tin, and bend to fit) to the lugs of the Oyaide IEC inlet. Trying to crimp the Oyaide Fastons is a major chore as the metal is quite stiff....and why not eliminate another metal in the way of an easy, clean solder joint (on the lugs)?

 Well, we can debate the benefits a gas-free crimped connection versus a soldered one until the cows return. That debate has been aired on these forums many times in the past. I find myself in the crimp camp. You sound as though you are in the other camp. Likely we'll never convince one another. I kind of keep coming back to the idea of why introduce a third or fourth or fifth type of metal into the equation by using solder?

 

is it possible to clamp and solder the tignt wires? (in a way the clamp can be removed afterwards?) nt, posted on December 21, 2016 at 19:59:24

sadly my 'moniker' 4px=y² fails each time to include the (²) and screws up any chance at modifying a post LOL nt, posted on December 21, 2016 at 20:05:12

 ....is trying to crimp those non-plyable Oyaide Fastons. There is little give in them. That's one of the reasons why I recommended soldering.

Perhaps if one invests in the ultra-expensive, dedicated crimping tool then you can have your cake, etc. etc. But for just one or two applications?

I have no stake in arguing soldering vs. crimping....whatever you wish is fine with me.

 Alan,

I talked again with Mike. He told me he had a cheap (like $40) Klein tool that was very close to being the correct size. He was going to take it to a machinist buddy to see about milling the jaw so it'd be a perfect fit. I'll let you know I what kind of success he has with that. And you are bang on with your assessment of the rigidity of those tabs. Without the correct tool they are a PITA to get them to form a proper crimp.

 

Exactly....keep us posted., posted on December 23, 2016 at 12:10:18
