Gang, this is close to the subject line. It might prove handy for someone who
wants a (blush) QRO -386-type chip.
 
I recently got one of those cute little RS amplifier kits to give more oomph
to my 30-40. It is rated to 1 watt (I think) at 12 volts and uses a single-in-
line chip marked NJM386BS. That number is one of those familiar/strange
numbers kinda like the LM 386, but not quite. Being a SIP, it has a different
pin-out than the LM 386, but very similar circuitry in the R-S board. I asked
for help on the list and got the following reply:

Now that Danny is in limbo (or some other small WY/MT town), anybody got
another source?
