Which ones? I've done 4 with 0 issues There's just the one inductor, right? In both my kits, the inductor legs are way too big for the holes in the PCB. It's weird though, the legs fit easily through the holes in the circle that the inductor covers up, and the inductor comes with one leg bent all the way like you'd do if you were going to vertically orient it like that, but the bent leg isn't long enough to get through the PCB and also the build guide doesn't have you putting it there. The holes the build guide has you using are the small ones that don't fit. Something is up. Any insight? Hi Hmm mine fit no issues.see below Attachment DeletedI think the trick is to get them as straight through the hole as possible. Then it goes in. |

Hi Hmm mine fit no issues.see below View AttachmentI think the trick is to get them as straight through the hole as possible. Then it goes in. Ok good to know. It’s a PCB issue on mine. They’re not close to fitting, even carefully trying with pliers. I was able to get a lot of straight force on it and it’s a no go. I cut the legs short and cut the end into a taper and was able to get them to nest in the pad and solder. It’ll be fine electrically but there’s definitely an issue. And weirdly, the email Peterson had been using with me is now throwing mailer errors and getting returned. Thanks. |

That's odd yours would be like that considering they would be batch orders. Email is also odd. Which one are you using? Does it fit in the other board? Century Link is having nation wide issues too could be related? |

Decided to pull the trigger on a pair of these. I hope I can find some time to build em!!! Look forward to it. I'll eventually swap out the stock transformers with Jeff's litz versions....

Is there a desoldering solution that isn't big money? Lots of people down on the little solder sucker pump units. I was going too quickly on the second EQP5 and I put the damn 100k resistor array in backwards. : ( In looking at the data sheet for that part, it looks like it might be a bit bulky for me to build the array from individual resistors. I'm gonna get a replacement array on the way but I should really have a desoldering solution here. Only so many situations that a toothpick can get you out of. matt@IAA Blackdawg |

Did you try desoldering braid? You can also try heating it up and take a can of air to it. It will blast it all over the place so make sure you find it all!

I like to use a heat gun on those. Solder suck as much as you can, then heat gun the bottom, pull it off.

The little spring action ones, or braid.

Only so many situations that a toothpick can get you out of. matt@IAA Blackdawg I did that once on the DIYRE summing mixer. Best way to do it per Petersons instructions was to use clippers and cut the resistor up into chunks so you only had to desolder one or two pins at a time. Worked great for me. He also sent me another resistor array for free |

I think you'll like them. Let me I'll solder them up for you if you want. Wow. Very generous offer Blackdawg - but I'm kind of looking forward to building them.  They look pretty easy, and the weather has turned cold. (No motorcycle riding) Maybe I'll be able to get em done quick. But if not...... I know where to find you. Cheers, bp |

No problem! They are a quick build so I'm sure you'll have them done very quickly. This are the transformers I'm using yes. Fit right in. Just follow Jeff's color guide for the normal 2503 as the 2503L has different colors. |

I dig these things. I'm waiting on a replacement resistor array but I split a mix into dual mono and printed through the one I have functioning and then put it back together into stereo and blind AB'd with the dry and I picked the EQP5 100% of the time. I was hardly doing anything EQ-wise but they were giving me a smoothness and solidity that my ear gravitated towards. Great low end and really nice de-harshing high mids with a tiny bit of 10k cut. I've also messed with them on individual sources and been really liking what they do. Very cool.

I just finished 4 of the 8 opamps. 4 to go then I'll do a comparison between all 6 pairs. Still haven't been back to the studio yet to try the 2503L tranny pair I have. May do that tomorrow but tracking the next 6 days so unlikely for a while. |

All was going so well.... :-) I built the DIYRE 500 extenders, then several colour modules. Smooth sailing.... Everything was going perfectly. Then I started in on the EQP's. I got most of the way thru one before my wife got home and I started talking with her while i was building. Bad choice. I got distracted and soldered all 4 pots on the wrong side of the board. AAaaaarggggh. Dumb newbie move on my part. Tried to remove one and after 45 minutes I torched it. I guess it's time to buy that Hakko desoldering iron that I should have bought years ago. Sigh. These EQ;s just got a lot more expensive. Still I'm sure they will be worth it. This EQ is in deep freeze until the Hakko shows up.... Oh well, I'll be more careful on the 2nd one.... |

Damn that sucks. shoulda just let me do it  just kidding. It'll be worth it. Those desoldering guns are nice and affordable now too. Well worth it for the avid DIYer. I need to get one too. I have success using the hot air solder gun to do multi pin stuff though too. The Quick Chip stuff is good too. |

Yup. Coulda, Woulda, Shoulda..... Too late now. The Hakko's are pricey. At least for me. Cheapest I could find one was $250. I guess a new EQP would have set me back another 2, so, not so bad. I've managed without one for a couple of decades. But I just couldn't get these out... |

Interesting.... Unfortunately, too late. I've already ordered the Hakko. We'll see how it shakes out. One thing is for sure - taking out pots is a magnatude harder than a resistor. Will try that if the Hakko doesnt' make it, but I think it will work. Still waiting to hear back from Peterson on spare parts. Hoping I don't have to order a whole nuther kit. |

I'm in a session so spare time is low this last week. Sorry was too slow. I'm sure Peterson will get you parts. He's done it for me. Might just be catching up on backlog of emails from holiday season |

Hi Hmm mine fit no issues.see below I think the trick is to get them as straight through the hole as possible. Then it goes in. Peterson got back to me and says he's pulled all the PCBs with the size issue out of inventory so hopefully no one else is getting them shipped to them. There was definitely an issue. Mine weren't close to fitting. |
