I’m having a hard time sourcing the 2SK208-R. I’d like to find an equivalent version in a through-hole. Any help will be greatly appreciated.
IIRC, the 2SK30A is a very close thru-hole equivalent, but it’s obsolete. How close does it have to be? Will your application allow a J201?
@johnathan Thanks for your response. I’m just trying to duplicate the J-FET circuit posted last month, so I’m not sure if it’s close enough or not. So I’ll check out the 2SK30A. Thanks!
@ovi4 Thanks so much for your reply. I’m looking for through-hole, I.E. TO-92. Those seem to be as rare as hen’s teeth.
@kooth However, if you only and purely need those for testing and/or experimentation you can very quickly fetch a simple DIY made tiny PCB in which you solder an SMD style J-Fet and attach some long leeds to it, job done in a mater of 4-5 minutes. You can even scratch some channels on a small PCB (using a small knife blade) to make 3 individual traces. As a matter of fact Mr Carlson made some PCB designs for all sorts of SMD components so he can experiment with them on any breadboard and he also published some of his designs on Patreon some time back (but cannot recall the exact video numbers) so, if you search the list of videos you will definitely find them buried somewhere on that list. Alternatively, you can buy them cheaply priced especially from some of the well-known Chinese websites such as: AliExpress, GearBest, Banggood, Temu, etc. I use them all the time when experimenting because as the time passes the tendency (now days) is that the component manufacturers prefer them as opposed to the classic components simply because they are much cheaper to make and being small they can store them with less costs in smaller spaces too etc. I am pretty sure that the classic components will one day no longer be manufactured and…who knows… that day might be just around the corner… PS: good luck with your amp/preamp experiments.
