So I'm wanting to build a Chop Shop. I've read that it can be picky about it's J201 JFETs, and read in another thread that ideally you want Q1 to have an Idss in the 600-800 uA range and Q2 an Idss around 400-600uA. I have not worked with JFETs before, but I assume this means that I should buy more than two in order to find to find suitable values.
Where's a good source for some J201s? Looking at my usual sources, Tayda and Small Bear seem to be sold out, they're $5 a piece at Mouser or Amplified Parts, but on ebay I see listings of ten or so for around $15; can I trust the ones on ebay? And then theres surface mount options, but I've never worked with surface mount parts and I fear that my non-adjustable 35 watt soldering iron may be too hot for them.
Also: testing? I've seen that RG Keen has a JFET testing article, anything else I should be looking at?
