I've got MKT 10 uf 63 volt as coupler caps in my Hammond organ preamp. As the organ only generates frequencies up to 7 khz, this is not a demanding application. MKT is polyester dielectric. John Curl, other senior diyaudio posters, much prefer polyprophylene as a dielectric for capacitors in the sound path. They say it is more linear. I don't have a stocking source of MKP with a broad line that will ship 1-2 days surface for <$6 like newark will. The MKT were expensive enough at $2.10 each. My organ has 6 preamps and I used a dozen of them. The MKT did sound way better than the dried up 1967 electrolytic caps previously installed, restoring bass response and imparting sparkle to the glock and xylophone "percussion" (attack) features.
edit, the bag says MKT and polyester dielectric.

I have access to both MKP and MKT types.
I have used them to replace old phase splitter caps in vintage cinema amplifiers.
I measured them at 500V and the MKTs came in with less leakage however both types were well up into the 10s of gig ohms.
I tested all of them as the valves are expensive EL37s and the output transformers would be costly to rewind.

The capacitor of VISHAY MKT1813-10UF
After a Running of 50 hours
Really excellent
Accurate and detailed
Especially at high frequencies
I order
VISHAY MKP 735P-10UF
And I showed how there is a difference between
