Source for resistors for an acoustech/sutherland phono preamp

Nude Vishays took over from the ones that are potted. These days Texas Instruments is the US source for what look like nude Vishay, series TX2575, at about $12 each. Caddock TF020 from M Percy sound just as good for more like $5 each, but the form factor can be a little tricky to install. My opinions of course.

I just reached out to Michael Percy regarding some high quality 47k, 100K, 100R, 1000R rca plugs for my JLTI that I'm finally using after 3 years. It had a terrible hiss, so I put it in the closet. Recently Chakster helped me get the Luxmann up with arms and carts, JLTI is loaded and sounds great. No hissing. Still need those MM plugs!

How is Chakster?

Expensive resistors are not going to cure hiss, unless an existing resistor is "broken", in which case any fully functional resistor of the same value and equal or better voltage and wattage rating will also cure the hiss.  What I am saying is that cheap or run of the mill resistors that are fully functional at their rated value in ohms are not the cause of hiss.

But apparently putting your JLTI in the closet for a few years did cure the hiss.

is it true that using Shunyata Black Mamba and Audioquest King Cobra together changes the hiss level?
