luvdunhill Posted August 9, 2011 Report Posted August 9, 2011 I have a quick group buy going here for the 10m90s if anyone is interested: http://www.diyaudio.com/forums/group-buys/194262-ic-ixys-ixcp10m90s-group-buy-quick.html Almost at the goal, at which point I'll close the group buy, so get 'em while they are hot!
minivan Posted August 9, 2011 Report Posted August 9, 2011 if you are going to order from future electronic, i wonder if you can help us out by ordering some 4171g insulators from them as well? shipping cost is a bit high from future electronic for individual buy. i can get the 4170g insulator from mouser but they are over 60cent per piece vs the 20 cents 4171g ones from future i need 100 of those 4171g.

If you feel okay putting those in a padded envelope, then I might be willing to help.

My post is still in the moderation queue, but I could take the minimum amount or at least 8.

wink Posted August 10, 2011 Report Posted August 10, 2011 Can't find the LSK389/2SK389's in the preliminary BOM......
jantze Posted August 10, 2011 Report Posted August 10, 2011 Can't find the LSK389/2SK389's in the preliminary BOM...... It's in the other tab, click "AMP" from the bottom of that spreadsheet.
Milosz Posted August 10, 2011 Report Posted August 10, 2011 Just in... Insanely heavy. Gonna take a couple days to classify the boards. WOW! Don't injure your back moving those boxes around!
Lil Knight Posted August 11, 2011 Author Report Posted August 11, 2011 Shipped a couple of packages today, I will send the invoice including shipping cost and pic of shipping slip. Birgir's package got stuck for a day because my local PO couldn't find Iceland's country code (wtf indeed). Should be able to solve this tomorrow. I'm trying to source for packing material so it might take some days to ship, hope you guys don't mind that. I just ship the boards basing on the boxes I have on hands. If anyone could do direct bank transfer, please let me, really want to get rid of Paypal business. So much hassle.
chinsettawong Posted August 11, 2011 Report Posted August 11, 2011 Wow, I just noticed that my package was the first one being shipped out. Thank you very much. I'll PayPal you tonight. Wachara C.
Kerry Posted August 11, 2011 Report Posted August 11, 2011 I was just looking at the BOM for the KGSSHV power supply. The bridge diodes you have listed in the BOM (511-STTH1512W) look like they are too big. I looked up the part number on Mouser. I think you need TO-220, not TO-247. I haven't gone in great detail yet, but I just happened to notice this. Thanks for pulling this all together.

I haven't gone in great detail yet, but I just happened to notice this. Thanks for pulling this all together. Mouser doesnt carry the TO-220 parts with the same electrical specifications. In my KGSSHV I used the TO-247 ones that Lil Knight specified, but I dont recommend it to anyone else because I had to do a lot of rework to the terminals to make them fit the pcb footprint. (bending and trimming the leg width with a dremel tool.) And yes, they are too big. There was an earlier discussion about this in the KGSSHV thread. I believe that Luvdunhill and KG concurred that a similar part with a lower continuous current (<15A) could be used (as low as 8A ?? - I would shoot for at least 10 to 12 A), but they must be a fast recovery type with the 1200 volt reverse voltage withstanding spec. I'm sure that some of the other major suppliers will have these in stock. Edited August 12, 2011 by livewire
ujamerstand Posted August 12, 2011 Report Posted August 12, 2011 god damn it! Well, the D version of these parts are out of stock at all the major distributors and mouser marked it as obsolete. Any substitute for this part?
cobra_kai Posted August 12, 2011 Report Posted August 12, 2011 (edited) How important is the forward voltage drop? I am guessing not too important since these are just rectifier diodes. STmicro makes an 8 amp one in TO220 packaging: http://www.mouser.co...vKRkUrKFUiXk%3d Fairchild makes this one: http://www.mouser.co...oEsfgWd1k1R8%3d 15 amp but forward voltage drop of 3.2V instead of 2.2V IXYS also makes one http://www.mouser.co...PcBtS1NgYoiU%3d with 2.75V forward drop Edited August 12, 2011 by cobra_kai

Thanks for the check. I made the BOM editable now so please help me add the correct parts' numbers. Edited August 12, 2011 by Lil Knight
Horio Posted August 12, 2011 Report Posted August 12, 2011 Ouch... I guess I should have paid attention to the rectifiers more before I ordered 25 of them...=( Is the 1200V rating a must? There is also a 1000V/12A STM rectifier as well: STTH-1210D
Lil Knight Posted August 12, 2011 Author Report Posted August 12, 2011 ^ Sorry about that, Greg 1000v diodes should work fine. deepak will help me distribute the T2 boards in the US, so Deadneddz, n3rdling, livewire, inu, cobra_kai, bada bing, Milosz and justin will be in that group. Also he will include KG, digger, blubliss, Kerry, El_doug, horio and morphsci too. Just want to let everyone know in advance. Sorry about this but the T2 takes damn a lot of time to pack and I might not have enough material. Just want to move the boards out as fast as possible. For the other in the US, Driftwood will be another distributor. Anyone in the US can give him a hand, please let me know.
livewire Posted August 12, 2011 Report Posted August 12, 2011 (edited) QUOTE: "Is the 1200V rating a must?" KG would have to chime in on that one. The search function isnt working or I would reference what he said previously in the other thread. Look on the bright side, if returning them is a hassle, they ARE useable, they WILL fit. Just need a few hours of careful, patient rework. That is, if you are good with that kind of thing. Why are you selling your SR-507's? Edited August 12, 2011 by livewire
deepak Posted August 12, 2011 Report Posted August 12, 2011 If anyone wants to do me a favor and link to some place that sells bubble envelopes big enough for the T2 amp board (plus thick enough for the PSU board, and other boards and cardboard inserts) that would be great (it will be so much cheaper than having the UPS store pack them)

Horio Posted August 12, 2011 Report Posted August 12, 2011 No worries Tran, I think I might be able to use these on a couple of stereo amps I have been working on. So its not a total loss. Why are you selling your SR-507's? I ended up finding a nice pair of used Omega 2's, and I couldn't justify having both at the moment. Maybe down the road I can, or maybe I'll get a pair of 009's to go with my O2's...

I believe KG used bubble wrap envelopes with cardboard inserts to send the original T2 boards out

Packaging the stuffs now...
