This is going to be my DIY pick for the May meeting, but since the pre-order is over before the meeting I thought I would post this for those that want to get in on this right now.  This looks to be a very easy build and probably a good starting point for a new DIY'er. Nelson Pass should need no introduction. I ordered 2 kits to allow for mono block operation. When I get this built, I will hopefully be able to demo it at a future DCHFG meeting. Should be a good fit for Gary's horns? Here's the link to the order page. There's a great video link there as well showing how to build. |

Have to wait until the end of July. I HATE waiting. Have always admired Nelson Pass. Yes, would be a very interesting pairing with Gary's horns. Ordered a pair.

Absolutely, we've got your back! Don't be afraid to ask any questions I just got the case parts and expect the PCB soon. I'll try to dig in fairly quickly so I can field questions. Don't forget to look at the videos and other resources on line. I use a Weller solder station I have had for a while: Weller WLC100The Hakko is a very popular choice as well for a bit more money. I also just got a PCB holder that you might consider. PCB HolderIf you have a broken piece of electronics lying around, you could practice de-soldering and soldering with that? Get some Solder Wick for de-soldering: Solder Wick |

Thanks. Practicing on an old piece of electronics is a good idea. Any guidelines on whether to wick up old solder or vacuum it? with the Soldapault

Depends. When trying to remove solder from an eyelet or hole the sucker works better. When cleaning up a pad on a board or when you want to get to the very last drop of solder the wick works better. You really need both. After a while you will get a feeling for which you should use and sometimes both.

To change the direction of the conversation - but in keeping with the Amp Camp Amp discussion - what are the thoughts concerning the speakers that will be used with them? I have what I think to be some fine speakers (Magnepan, KEF, Totem) but none are probably sensitive enough to be driven adequately by the ACAs even in bridged mode. For some reason I really can't explain, I am lately intrigued by open baffle speakers (some perversion of my proclivity for planars?) and especially by the notion of building same. What are others thinking about in terms of speakers for the ACA?

Has me thinking of Spatial Audio Open Baffle.

Has me thinking of Spatial Audio Open Baffle. Yes - as we heard at Linear Tube Audio. I quite liked them. But given that the ACA will be homebuilt, I'm leaning toward the same for the speakers. |

Chris did you finish the amp camp builds I really want to try some class A amps, would you be interested in letting me try them?

I received my chassis from Italy this week. I think there are still two more parts shipments to complete all parts for the kit. I was impressed by the high end worthy metal work. And, I betray my age when I say I remember tissue paper weight airmail stationary, but it blows me away that it only takes four days for FedEx to deliver from the manufacturer in Italy to my doorstep in NoVA.

Just a quick update to report that I have successfully built the first of two Amp Kits I ordered and it is running nicely and playing music! The 1.6 kit instructions are now online and are very good with good pictures and some videos as well. I found populating the PCBs to be very straight forward. For me, the wiring was the more challenging part but with all the good pictures it went very well. You may want to break up your build into two parts by populating the PCBS first and then do the wiring and assembly in another session. I did find what I think is some incorrect text for the back panel wiring even though the pictures were correct. When in doubt always refer to the pictures and you will be fine. I also wish they would specify actual lengths of wire for specific hookups. I had to redo some wires related to the front panel switch and power (red wires) because I ran out of length to get everything hooked up. Not a big deal but having exact measurements would be helpful here. All in all I am very pleased with the result and can't wait to get the other kit done so I can have even more power. I will bring the amp to the next meeting for people to admire. Here are some pics of my build.
