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. Mine don't fit either Ragan, and I just ordered them a week ago. What did you do to make the inductor fit? I couldn't get mine to fit any way, any how. I ultimately just scabbed on a piece of resistor leg to the inductor fat leg - kind of like a skinny peg leg on a fat thigh, and soldered that. Seemed ok.... But then again, I never got them finished,,,,,, LOL |

Still waiting to hear back from Peterson on spare parts. Hoping I don't have to order a whole nuther kit. 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 Thx. Yes! Peterson got back to me, and parts are on the way tomorrow!! <thumbsup> |

Mine weren't close to fitting. Damn. I guess I got lucky then. Funny as I received 4 kits after deciding to change my order. Sent the other two back. Wonder how I ended up with a good pcb. Is he replacing yours? Or you doing a work around? 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 Thx. Yes! Peterson got back to me, and parts are on the way tomorrow!! <thumbsup> Sounds like you should ask about the pcb issue too according to ragan. |

But then again, I never got them finished,,,,,, LOL Yeah, it's not even close to fitting. I just snipped the inductor leg short and at a taper and that let me poke that tapered leg into the PCB hole/pad. I could actually jam it in there good enough that it was stuck decently even with no solder. Then I just gave it a generous bit of solder. Not ideal of course but it's still fastened quite securely. I just wanted to get the damn things up and running and wasn't hearing back from DIYRE so I improvised. Also, barring some really weird shit, that inductor joint isn't ever going to be under any real stress so I think it's fine. |

If anyone who's got the 2503 Litz soldered in as replacement for the stock transformer could take a pic and post it, I'd sure be grateful. I'm not really understanding Jeff's pic as he's showing 8 wires coming off the 2503L and there are only 6 coming off the stock transformer. Many thanks!! bp

Thanks! Yeah, I was aware of that. Just not sure how to hook up an 8 wire transformer as compared to the DIY 6 wire one.... I suppose I could just go for it....  Anyone willing to snap a pic? |

Yes I have one. I'll post at lunch break. Just match the pads withe EA colors on jeffs sheet. there are 8 pads for the 2503 style transformer. The stock one just uses the inner 6. |

Here you go drbill    Image sharing on this forum really really sucks. That was a pita. anyways colors go: Red-Pink-Yellow-Orange-Black-Gray-White-Purple. Don't mind the crap stripping job I did on the purple one. Didn't get the fan out right. Still goes all the way through. |

Thanks Blackdawg!!! image isn't showing up, but I just ended up going for it, and did pretty much what I think you're suggesting above. Worked perfectly right out of the gate. Thx!! Now.....waiting on that Hakko solder sucker so I can finish the first one. |

Now.....waiting on that Hakko solder sucker so I can finish the first one. Damn it. The image hosting here sucks. Should talk to John about changing forum software.. Anyways Glad you got it! |

OMG!!!!!! The Hakko desoldering gun is off the hook amazing. Honestly, it was like the heavens opened up. All 3 remaining pots removed in a couple of minutes. Now waiting on parts to finish....

Now waiting on parts to finish.... which model did you get? This is the one Brad M recommended : Hakko FR-301 www.tequipment.net/Hakko/FR-301/Desoldering-Equipment/Rework-Stations/?v=0$$246.75 delivered. Super quick service. |

I used the new Hakko 301 to rebuild the Harrison Mr-3. I was even able to desolder 8 pole switches without damage.
After hundreds of projects, I wore out the 808. The 301 is lighter and a great improvement.
Welcome to DIY.

No, They are not interchangeable.
But the 301 stock tip did everything on the whole board caps and switches and still works like new.

Got the replacement resistor array and had a brief play with the pair.
I LOVE THESE THINGS.
I'll print individual tracks through them for sure but they're gonna live on my mixbus. They do *such* a cool tightening thing with the slightest boost/cut in both registers. Putting a smile on my face for sure.
Build was fun and (barring the PCB issue and the resistor array that I mangled) easy.

Build was fun and (barring the PCB issue and the resistor array that I mangled) easy. They are awesome aren't they? Hit way above their price point. Can't wait to demo the new ones I built with the new transformers. Then Im going to demo all the opamps I built. Curious to see how drbill will use his pending repairs haha |

Also, I got a $7 spring/pump solder sucker and the damn thing works like a charm. Can't believe how many projects I've done without it.  |

Along with the braided solder wick I got along pretty well. But when I tried it this time on the pots, it seemed like somewhere along the line it got broken. That's when I just decided to bite the bullet and get the Hakko. Compared to the real deal solder sucker though.....OMG - what a difference in speed and ease. The Hakko was another huge step up. Give one a try sometime if you do a lot of DIY. I'm blown away. I don't do much DIY anymore, but even still, I think I'll be keeping this thing. The stress relief, and speed alone make it worthwhile. |

Hopefully I'll be getting the parts today if USPS doesn't screw up. Then I'll get them both wrapped up. I've got the vintage outputs in mine with Litz transformers. Stock 5532 opamps. |

Yeah I've no doubt a real desoldering setup like the Hakko is way better. I'm sure I'll get one at some point. |

Hope you get to hear them soon! My new pair is configured the same. Can't wait to AB them with the all stock vintage output. I'd still like to swap opamps too as some point for the ones Jim uses a lot. Plus I have 6 discreet opamps to try out on the output to see what I like. |

If you're feeling up to it grabbing some SOIC to DIP8 boards and swapping those 5532's out with an SOIC OPA1612 definitely sounds better. It might just be the differential setup but I swapped between the two many times and it's undeniable the 1612's are much smoother on the frontend. Brads DOA's sound great in nearly everything on the backend of these, although I think I'm running SL1731's ATM. |
