[R-390] Need Resistor info

Hello, got your shotgun loaded, do you?

Vishay? Wasn't their specialty high resistance precision resistors?

I suppose each of us has got to do what the voices tell us to do, but
this seems extreme. It's a communications receiver, not a precision
measurement device. Do not expect precision resistors (or capacitors)
to improve the performance of a radio that depends on its mixers,
crystals and the Q of its tuned circuits. Or perhaps you are one of
those audiophiles who looks for perfection in all the wrong places?

Apologies if I've missed the mark . . .

GM List,

I have in the neighborhood of 16 + BA’s to rehab.  Since I have to do all
this re-capping it seems
sensible to replace the old carbon comps while I’m in there.  (Especially
all the 2K2 1/2 W units
in the R390’s with 1 watt 2K2’s.

Question: has anyone had any experience with the KOA-Speer or Xicon metal
film and carbon film
resistors sold by Mouser.  The price is right in the 100’s.  I’d prefer to
buy Vishay’s but at the
quantity I’m looking at there is a huge price jump.

I could use Vishay’s in the front end and the el-cheapo’s for the rest.

Any thought appreciated.  Regards, Perrier
