I really hope their website is correct because I got quite a few...
I just sent an email inquiring about this to NTE's customer service, I'll post here any response I receive.
I am pretty sure, but please let us know what you find. I spoke with several vendors trying to track down any MF they may still have in stock over the summer. A couple confirmed that NTE phased out MF, the shiny blue type you see in many Dumbles and replaced them with MO the dull greyish type you have.

I also sent an inquiry to nteinc.com tech assist. Their datasheet just says "METAL" on the top, not specifying Film or Oxide. Now I'm not so sure they are MF like I was before. Regardless I'm going to see how they sound. If I don't like them I've got a full set of CF from Jelle I can put in with current production Dale RN and CMF MF for plates and cats.
Yes I'll definitely post any replies I get from NTE, but might be some time with the Holidays....
metal oxide and metal film are all FILM, correct name for metal oxide is metal oxide film..
i think that NTE is MOX blue and gray version the same, only old/new, but to be sure must be destroyed and compare the resistance track inside between those NTE and regular MOX resistor....i never did because i find NTE so rarely in this part of the planet

Be careful with this here, the resistor will short once the conformal coating gives out. I would move it away from the nut. jelle
