spritzer Posted January 15, 2013 Report Share Posted January 15, 2013 2SC4686 is EOL as well. Fuckers... Quote Link to comment Share on other sites More sharing options...
eggil Posted January 15, 2013 Report Share Posted January 15, 2013 (edited) That really sucks. How can we continue to build as some parts become more and more scarce? Megatron it is then!! I already started the hunt for that build. Edited January 15, 2013 by eggil Quote Link to comment Share on other sites More sharing options...
shipsupt Posted January 15, 2013 Report Share Posted January 15, 2013 (edited) I should have looked harder... they were right under my nose. I just ordered 25 from Bdent. I was so surprised that they had them in stock after not finding them at a bunch of other suppliers that I called and he confirmed he has them. I'm not sure how many he has, but if anyone is looking you might consider checking with him. $4.95 each I was also able to get the Toshiba 2SC2705's and 2SC1815's which were also showing obsolete on Mouser as well. Of course I'm not counting chickens yet, not until I have them in hand, but I'm feeling better tonight than I did last night!

spritzer Posted January 16, 2013 Report Share Posted January 16, 2013 If this trend continues then we are indeed looking at just tubes for high voltage use or stacking lower voltage parts. One HV transistor that is cheap and easy to source is the Fairchild 5027 but the gate capacitance is quite high... Quote Link to comment Share on other sites More sharing options...
Victor Chew Posted January 17, 2013 Report Share Posted January 17, 2013 Mouser is out of 2n3904. The order page suggests replacement with http://sg.mouser.com/search/ProductDetail.aspx?R=863-2N4401G Has anyone tried it yet? The specs are almost identical except it can take higher current at 0.6A as supposed to the 0.2A. Quote Link to comment Share on other sites More sharing options...
Pars Posted January 18, 2013 Report Share Posted January 18, 2013 2N3904s should be a very generic transistor... Fairchild or ON Semi should be fine? They seem to have all kinds of them. http://sg.mouser.com/Search/Refine.aspx?Keyword=2n3904 Quote Link to comment Share on other sites More sharing options...

spritzer Posted January 18, 2013 Report Share Posted January 18, 2013 Yeah this is a generic part so any manufacturer will do. Quote Link to comment Share on other sites More sharing options...
Pixiy Posted January 19, 2013 Report Share Posted January 19, 2013 I am just wondering where can I find some lsk389s. It seems that BDent is out of stock. Quote Link to comment Share on other sites More sharing options...

livewire Posted January 19, 2013 Report Share Posted January 19, 2013 (edited) You're welcome. What are you building? KGSSHV? Edited January 19, 2013 by livewire Quote Link to comment Share on other sites More sharing options...
Pixiy Posted January 19, 2013 Report Share Posted January 19, 2013 I want to build a headamp with HV's input state and T2's output stae, but I am not really sure how to do. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted January 19, 2013 Author Report Share Posted January 19, 2013 That's basically a BH Kerry has a slightly different design with the kgsshv input stage, The active battery and the t2 output stage. Quote Link to comment Share on other sites More sharing options...

eggil Posted January 20, 2013 Report Share Posted January 20, 2013 Does that mean you will have more time to design amplifiers? Quote Link to comment Share on other sites More sharing options...
wink Posted January 20, 2013 Report Share Posted January 20, 2013 No, just more time to finish the two KGSSHV's in between job-hunting. Quote Link to comment Share on other sites More sharing options...
