[TechAssist] Re: Pioneer\SDP50A3K...DEAD

Who sells the STK392-180?  My supplier has never heard of them.

Walter,

I would take this an additional step and always use the STK392 -180 for
the -110 in any brand set.  I placed a note in my parts log to
substitute
the -180 for the -110.  Don't trust my memory.

I do the same thing for the STK730 series regulators.  For the -010,
-020, -030, -040, or -130--I use an STK730-090.  Is rated higher than
the
rest.  Besides, cuts down on stock and saves money by ordering in larger
quantity.

Probably many others, but one more I remember.  I use the LA7838 for
either the 7837 or the 7838.

Thanks for the tip, Walter.
