mettula Posted March 3, 2006 Report Share Posted March 3, 2006 i wish to ask again :-[ :-[ :-[ i am not good in electronics :-[ :-[ :-[ can i for the schematic of veronica 1w pll pro use 2N2219 or 2N3553 or something equvalent instead of the BF494??? my local shop has nt BF494 or BF 184 thanks a lot :-[ :-[ :-[and can anyone suggest a page for transistor equivalent plzzzzzzz Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 Hello Mettula I am new to electronics too and understanding the difference in transistors is a project all in its own. I found the data sheet for the BF494 and will post it. And try to come up with something for. Boy wish I could find data sheets for my collection or transistors. good luck gogo42501001.pdf Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 4, 2006 Report Share Posted March 4, 2006 Hi Gogo,You can find most datasheets for old and new semiconductor products at www.datasheetarchive.com . Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 Thanks audioguru I will give a try. Right now I am in hot persuit of info on a power transister SK B1382. Just because I have one and I want to see what it can do. I hope that makes sense. Thanks gogo Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 I gave it a shot. Darn no luck, Its just a transistor I got out of a old printer, its in good shape but no info yet. Hmmmmmmmmmmm gogo Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 4, 2006 Report Share Posted March 4, 2006 Maybe the power transistor SK B1382 is really a power Mosfet made by Toshiba with their part no. 2SK1382. The datasheet is available at www.datasheetarchive.com . Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 Thanks audioguru I didn't find it at data sheetarchive, but I did a search string on 2sk1382 and found the data sheet at http://katalog.elektroda.net/indx450-2SK.html nice I got it. With your help Thank You gogoe001347.pdf Quote Link to comment Share on other sites More sharing options...
mettula Posted March 4, 2006 Author Report Share Posted March 4, 2006 But are SK B1382 and 2SK1382 equvalents of BF494? or as i said can i use 2N2219 of BF3553 Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 No the 2sk1382 won't work. sorry but I will do some research tonight and see what I can come up with. gogo Quote Link to comment Share on other sites More sharing options...
Staigen Posted March 4, 2006 Report Share Posted March 4, 2006 Hi mettulaWhere in the world are you living, the BF494 is one of the most common HF-transistors in the world! ;DTo gogo2520The B1382 can be a 2SB1382, Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 4, 2006 Report Share Posted March 4, 2006 Hello Staigen Your right about the BF494< I checked mouser and they have it for 20 cents. I check the data sheets on th 2SB1382 wow what a difference between it and the 2SK1382. The transistor Has SK under lined on top of the part number, So I am guessing that it was made by Sanken.

Staigen Posted March 4, 2006 Report Share Posted March 4, 2006 Hi gogo2520"Japanese" makers usally delete the 2S in front of their transistors type-number! ???//Staigen Quote Link to comment Share on other sites More sharing options...
mettula Posted March 4, 2006 Author Report Share Posted March 4, 2006 Hi mettulaWhere in the world are you living, the BF494 is one of the most common HF-transistors in the world! ;D//StaigenStaigen i live in Gozo a sister island of Malta - here few are in the rf field and many times for a school project or hobby we have to import components from abroad which makes projects expensive. some shops do provide help but sometimes this forum helps better ;D ;D ;D Quote Link to comment Share on other sites More sharing options...
Staigen Posted March 5, 2006 Report Share Posted March 5, 2006 HiDo Gozo belongs to Malta? Malta? Isn't that EU? I can buy a pair of BF494 for you, and send to you in a letter.//Staigen Quote Link to comment Share on other sites More sharing options...
mettula Posted March 5, 2006 Author Report Share Posted March 5, 2006 THANKS staigen for your offer, yeah indeed thanks a lot but i found a retired ex-army official and had a couple of BF494 which he sold me. Thanks again m8. and yes gozo - malta are an-eu country. YOU GUYS ROCK ;D ;D :) :) Quote Link to comment Share on other sites More sharing options...
Staigen Posted March 5, 2006 Report Share Posted March 5, 2006 Ok, how much did you have to pay for them? In euro, please!//Staigen Quote Link to comment Share on other sites More sharing options...
mettula Posted March 5, 2006 Author Report Share Posted March 5, 2006 they were around LM2.50 which makes approx 1-1.5 euwos for 5 transistors and acouple of heatsinks.... Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 5, 2006 Report Share Posted March 5, 2006 I think Mettula needs an entire Veronica FM transmitter kit, if it is still available. Quote Link to comment Share on other sites More sharing options...
mettula Posted March 5, 2006 Author Report Share Posted March 5, 2006 lol audioguru i finally collected all the parts - and yeah it would have been much easier if i would have bought it :P :P Quote Link to comment Share on other sites More sharing options...

mettula Posted March 5, 2006 Author Report Share Posted March 5, 2006 audioguru the varicap i found it - i am uploading the full schematic and files of the veronica including pcb, parts list instructions etc - more power to this comunity lol maybe u wanna use it somewhere elseveronica_1w_pll_pro_transmitter.rar Quote Link to comment Share on other sites More sharing options...
