[Elecraft] [OT] A question for Elecraft

The problem, in a nutshell, is that through-hole components are becoming 
increasingly hard to find.   It is for that reason that I am presently 
looking for, and purchasing, through-hole components in bulk  for that 
soon to come day when they are effectively no more.    Fortunately,  
they are  cheap right now, if you are careful what you buy.  For 
example. 2N3904 transistors are about 2.5 cents each if you buy them a 
thousand at a time.  (thats $25 per 1000). and 1N4007 diodes are 1.5 
cents each in similar quantities.  I have my own list of about 10 
different parts that will answer something like  90% of all ham radio 
and experimenter type applications.


What I am looking for is a source of small PCBs that can be used to 
adapt some of the surface-mount parts to through-hole circuitry.   Does 
anyone know of a source for such a thing?   For example,. where I can 
mount a SOT-4 type package on the PCB,. and then extend wire leads from 
the PCB to a conventional circuit.  This would re-open the world of 
dual-gate MOSFET parts that have disappeared altogether in through-hole 
form, but are available in quantity as surface-mount parts. .  (example: 
the 40673 dual-gate MOSFET that was popular in so many older designs)


Just my 2 cents worth
