OK, sorry to drag this on, but I have experienced just how "anal" the danish customs can be about these kind of things (sorry for my constant "hiney-references").
They will retain your package and send you a letter telling you to declare the value of the package and document it with some kind of proof of purchase (receipt, payment transfer details etc.).
A purchase with a value (including shipment) of more than 16$ will be retained unless you are lucky enough to get through "under the radar" (I haven't in some time now, probably since it is a profit-machine for them).
OK, enough of my petty problems, on to the more constructive part.D1, D2, D5-D10
The Fairchild BZX55C12 is no longer available, I found only one alternative
but the parts list tells me to "not substitute with other types". I hope I am misinterpreting here and that my alternative will do the job fine, but I would like some reassurance.Q1, Q2: N-channel small signal JFET 2SK170BL (TO-92)
These can be found on eBay, but am I risking buying counterfeit parts?
I actually found a German seller listing these st
Mouser has seems to have a BLF variant
, but will it do?Q3, Q4: P-channel small signal JFET 2SJ74BL (TO-92)
These are also readily available on eBay, but same concerns as above...
Reichelt lists these as well, but they do not specify if it is the BL version
, I will ask them.
For this one, Mouser tries to offer me that same 2SK170BLF as above...Q5, Q6, Q11, Q12, Q15, Q16, Q17, Q25: NPN small signal BJT BC550C (TO-92)Mouser
has the BC550CG flavor on stock, data sheet is for the BC550C though so I reckon I will be safe buying these?Q7, Q8, Q9, Q10, Q13, Q14, Q18, Q26: PNP small signal BJT BC560C (TO-92)
Jackpot! Mouser has these
, admittedly they ARE scheduled for obsolescence and will be discontinued. An alternative could be the BC560CG variant from ON Semiconductor, would it be better to go this way to stick to the same manufacturer?Q19, Q20: N-channel small signal JFET PN4392 (TO-92)
Available from Mouser
, will be discontinued though, so I might stock up!Q21, Q23: N-channel power MOSFET International Rectifier IRFZ24N (TO-220AB)
I suppose Mouser also have these on stock (IRFZ24NPBF)
.Q22, Q24: P-channel power MOSFET International Rectifier IRF9Z34N (TO-220AB)
Mouser suggests IRF9Z34NPBF
Hmm, I guess that when putting a little effort into this many of those components ARE actually available from Mouser unless I am mistaken. Thing is, when I am told to look for "IRFZ24N" and Mouser only lists "IRFZ24NPBF" I am thrown into a panic fit, since I would just HATE ordering the wrong parts and blow something up (even just having to re-order would drive me crazy).
Oh, and why is a electronical illiterate like me taking on a project like this you might think. Well, to prove that even slow-pokes like myself can get away with making the allegedly awsomnest of headamps. Hmm, and because I asked around on a danish head-fi forum what project I should take on next. Plan is to do a writeup on the project as I did when I made the Panda Headamp as I have gotten some feedback that it encouraged people to take on the project themselves and since apparently it helped some builders that were stuck.
