The pre-crimped DF11 leads also not available from uk suppliers. Would have to pay £12 delivery from Mouser. Think I'll just hard wire leads to the pins . . .
Hey Tom,
Hockey season starts today. The Maple Leafs start tomorrow, I don't think that Boston will be easy.

I know it! I have my jersey ready! I hope for a series like the one against the Capitals last year. With a 'slight' twist, of course. 😉 GO LEAFS!
Good series, though. Was it five of seven games that went to overtime. Good hockey was played.
Thank you. Yeah. I rather like it.

Do they have the crimp terminals? (Mouser P/N: 798-DF11-2428SCF; Hirose P/N: DF11-2428SCF)
Get a few extra. Usually, you can make them work well enough by "crimping" them with a pair of end cutters (carefully) and soldering the wire in place.
I much prefer the pre-crimped leads, but desperate times call for desperate measures.
Tom
Yes I can get those. I'll try that, thanks.
I've also ordered a bunch of mixed sizes of bootlaces ferrules. If any of them fit snugly onto the pins then I might use those as connectors.

Depending on which model of the EPP/RPS-400 you're using (i.e. cage or cage-free), you can also just solder wires directly to the bottom of the PCB for the on/off and remote sense functions. Just be careful not to short anything out.
The output terminals are some pretty sturdy screw terminals. Any auto parts store should be able to help you out with some spade terminals that fit.

Just an FYI: I'm very much open for business, but following a software update, the shipping calculator on my website is broken. No wonder business has been slow lately. I'm working with the software vendor to get that fixed. Stay tuned.

Looks like my website is up and running again. Ahhh... The joy of eCommerce. 🙂
Pardon the interruption.

My version of this amazing amplifier. I thought id share my experience of building this amplifier.
I went for a 3U Modushop case, 300VA 22V Airlink transformers, and 47000uF Kemet PEH200 capacitors. The soft start and speaker terminals came from Ebay, capacitors from Elektro Dump, most of the rest came from Farnell.
Anybody that has experience of using basic tools such as, Soldering iron, tape measure, pistol drill, files, screwdrivers Ext is capable of building this amp.
It was a bit of a squeeze fitting everything in due to the large capacitors I chose to use, but managed to just fit everything in. I mounted one board upside-down to keep the wiring symmetrical and the input away from the transformers. Mounting the Lm3886's was a bit messy as I used far to much thermal grease with the mica insulators. I soldered in the Lm3886'S by just to pins at first, marked out the holes and soldered the rest of the pins when the chips were fully mounted on the heat sinks. Most of the power supply wiring was done with some old speaker wire that I had left over. Everything else was fairly straight forward marking out drilling and filing.
After double checking the speaker terminals and Lm3886's were not shorting to ground, the polarity of the capacitors and rectifiers, I powered up, much to my relief everything was fine with only .5mv at the output and sweet sounds emanating from my speakers.

Directly from the text you quoted: "47000uF Kemet PEH200 capacitors". A Google search for exactly that term returns the data sheet: http://www.kemet.com/Lists/ProductCatalog/Attachments/391/KEM_A4034_PEH200.pdf

At that price I had to use them. They only just fit vertically in a 3u case though. The terminals are only about 5mm from the top of the lid. I've stuck a piece of sheet rubber on the underside of the lid for safety.
