Hagclock obsolete parts
« on: 27 Apr 2012, 03:38 pm »
My Hagclock is on the way (I hope) and I've run into a couple of snags.  The crystal is no longer available.  I've ordered an equivalent but it's SMD and I'll have to fashion some leads for it (ugh).  I also have a crystal of the right frequency pulled from a Rotel player - I'm tempted to use it but I don't know about the capacitance loading - Jim specifies 18pF.  How important is it that it be exactly right?

Also 2n5486 is long gone.  I'm kind of under the impression that this is kind of a jellybean part and that any jfet n-channel will do - at least I hope so, since Digikey has only two similar parts in stock - will this work?   http://search.digikey.com/us/en/products/J112/J112FS-ND/1048969

No, the J111 / J112 won't work well.
