deadlylover Posted September 24, 2011 Report Share Posted September 24, 2011 X3 I only had to deal with four or five people, I can't even imagine how much work went into organizing this entire board run. Many thanks Tran for letting us in! If you ever need anything from here down under..... Link to comment Share on other sites More sharing options...
Jaycalgary Posted September 25, 2011 Report Share Posted September 25, 2011 I would like to say thanks to Ujamerstand for the Bom Lil Knight for the boards. I am about to order all the parts and hope for the best with this build. I was hoping someone would tell me the right transformer to order from SumR? I should be happy if I can just get it together working but I really would like the smallest lightest chassis possible. I am going with off board heat sinks and have an idea in my head of how I would like to manage this. I am going to find a pair of aluminum heatsinks about 6in tall and 15in or so wide. the amp boards will be mounted vertically on the heat sinks on each sides and the psu board will be horizontal in between the two vertically mounted amp boards. The toroid will be in the back maybe even vertical to save more space. I will use quarter inch aluminum plate for the front and back relying on the heat sinks for side support and a vented lighter gauge aluminum for the top and bottom. Would this be a bad building practice with too much RF interference or possibly a good design? Link to comment Share on other sites More sharing options...
ujamerstand Posted September 25, 2011 Report Share Posted September 25, 2011 I'll add the specs into the BOM once I verified that the 450VAC transformer is able to generate the bias voltage without the voltage doubler. Link to comment Share on other sites More sharing options...
Horio Posted September 26, 2011 Report Share Posted September 26, 2011 I would like to say thanks to Ujamerstand for the Bom Lil Knight for the boards. I am about to order all the parts and hope for the best with this build. I was hoping someone would tell me the right transformer to order from SumR? Jay, I posted the transformer specs from SumR on the main KGSSHV thread Please note that transformer is targeted for a 500V output build. If you are building the standard 450V version, you will probably wanted a little lower voltage at the secondaries (probably 420V instead of 450V). I have the transformers in hand, and I should finish up the power supply this week. I hope to test it this weekend, and I will post how they work.

Lil Knight Posted October 2, 2011 Author Report Share Posted October 2, 2011 (edited) Good to hear that, guys. Right now Enrique (eggil) still 1x on-board, 1x off-board, 3x KGSSHV psu left since some people haven't paid (and I think they won't). Anyone in the CONUS interested in the boards, please contact me.

eggil Posted October 2, 2011 Report Share Posted October 2, 2011 Actually the only ones left are the ones mentioned in the spreadsheet from cancelled orders from wedge and mypasswordis, minus the one you want me to send arthur b. https://docs.google....&hl=en_US#gid=0 Link to comment Share on other sites More sharing options...

deepak Posted October 3, 2011 Report Share Posted October 3, 2011 Still waiting for 3 2 payments from T2 buyers. I really want to get these out in one trip since the PO isn't close to my house. Thanks to everyone that paid. Link to comment Share on other sites More sharing options...
JoaMat Posted October 3, 2011 Report Share Posted October 3, 2011 Deepak, If anyone of the T2 buyers cancel the buy of a T2 set - I happily buy one T2 set. Just PM me. And THANKS!! to you guys that have made this group buy possible. Link to comment Share on other sites More sharing options...

And THANKS!! to you guys that have made this group buy possible. I think these guys will want to build the most awesome electrostat amp ever! As far as I know the boards themselves are paid for, I just need to be paid for the shipping. The 6 people that paid were sent out this afternoon Link to comment Share on other sites More sharing options...
JoaMat Posted October 4, 2011 Report Share Posted October 4, 2011 Deepak, Thanks for the info. Tran connected me earlier today and he has promised to send one set of the T2. Link to comment Share on other sites More sharing options...
manaox2 Posted October 4, 2011 Report Share Posted October 4, 2011 (edited) Posting this here to spread the word, this is for the KGSSHV: The printing on the power supply board for BR1 is wrong. The "+" is at the wrong side. I guess it's a board from the current group buy (Production Rev 0.6). So be carefull if you have one of these boards. Yup, I just checked and the bridge for the +/-15V supply is indeed reversed. Just flip it over and you will be fine (- where + is marked).

Milosz Posted October 8, 2011 Report Share Posted October 8, 2011 (edited) My DIY T2 boards arrived safe and sound, my concern about shipping damage was unfounded. MANY THANKS TO ALL INVOLVED!!!! This T2 amp board is silly huge. I love it. Edited October 8, 2011 by Milosz Link to comment Share on other sites More sharing options...

deepak Posted October 9, 2011 Report Share Posted October 9, 2011 Moved a few posts to their respective build threads to keep it easy for those building these amps. Going to close the thread again, but PM me if someone needs it open for GB discussion/sales.
