That's a very striking design s_r, very attractive. Hope you're enjoying the sound quality.

The group buy used kgbhultraminipsV4 as at 21 July.

The board run I did was for 2 oz copper, 1.6mm FR4 HASL.

Yes - a very nice one Inu!

I must chip in here There is no official convention. I have a sort of mnemonic way of doing it. Bias is always white. Left channel has two colours with L in such as blue and yellow. The brighter being the more positive so yellow is the + output. The right channel has at least one colour with an R in such as grey, and the brighter one is pink or similar. This aids in checking you have it connected up correctly. It's pretty too.

Well done insanity. Bodes well for the listening test to come. Hope you like the musical quality And thank you Kevin and Birgir I like the KGST very much.

For some reason a couple of packets seem to be stuck in Kennedy NY. Perhaps customs hold them up? I have pm'ed you with details. Edit; to give feedback on this. NY Kennedy is where the packets disappear from UK tracking. I found on USPS that a couple were still in the system for various reasons.

Don't you have to pay for shipping and poss import duty on Antek? In Europe I think Toroidy are an excellent choice. If you are planning to run at the Birgir advised 350v, 280v ac will also be excellent.

That certainly would do it. although it is a bit beefy, as Birgir said a few posts back you can cut the HT current to 140mA. For Euro use you could have a single 230v primary.

It wasn't quite finished when I took this. The little 0.1 caps are missing. Toroidy.

Keeping my eye on it.

Yes that's the one. (edit; of course that doesn't mean that everyone should be fitting that value, just note you might have to adjust this) Public thank-you to Kevin and Birgir for the design and pcb layout for this very nice project. Birgir's and Kerry's comments encouraged me to build it and I'm pleased I did. The SQ is excellent. Mine is on a piece of plywood at the mo. To encourage those who have just got their pcbs;

Thanks guys, yes rumours of my death are greatly exaggerated. But seriously you're right DefQon. It was careless of me and I got off lightly.

I use these, it was all discussed in the KGSShv thread quite early on. Oxide pad 532-4170 Insulating washer 532-7721-3PPS

Very nice s-r, what size knob is that one? I must tell that when I was "testing" my last build. I reached in to move the input cable and my knuckle touched the power transistor at 450v. Well it was quite a jolt and I couldn't help but yell "f****** h***". I was wearing the phones at the time and there was a big noise in them also. There was a smell of vapourised flesh and the attached pic shows a neat crater in my knuckle. I am still alive apparently but I don't intend to try it again.

The pcbs look good thanks Kevin and Birgir. Have attached some images which will help builders. The zener voltages have been mentioned, notice on the PS the 0.1microF/1000v caps have a pin spacing of 15mm. Make sure the 24v zeners by the big caps are in the correct way as you'll not be able to get at them when it's assembled. On the amps the 0.1microF caps by the servo are very small 2.5mm lead pitch. Other than that it looks a very straightforward build. Have fun.

PCB group buy; The pcbs are in the post to you. Just come back from the Post Office -19 packets in the system. Give it up to a week.

Yes - good timing on that. The pcbs will be with me Monday 11 Aug and I'll be posting out over Monday /Tuesday.

Yes - for a day or two. LAST CALL FOR KGST

Group buy pcbs; I have just pm'ed everyone who asked for boards. If anyone else wants KGST amp or PS boards - shout now because the order will go in a few days. Confirm the number you want and I'll tell you how much to paypal me. Cheers

Thanks Birgir and Kevin, I have the files and am getting final price. I will pm all the people who requested boards and ask for you to confirm and do the paypal business.

Group buy announcement! See why I said there would be a short pause? As soon as these two gentlemen commit to a final for production for the group I will do the group buy. Hopefully in the next few days. I will pm all people who have put their names down for confirmation and payment. The total requests for amps was around 80 boards and PS 50.

Oh that's very cute indeed Birgir. This is going to be a fun project.
