Mundorf (non-oil) Silver / Gold EVO MCap Supreme coupling caps in your tube amp ???

UPDATE:
Doing more research and getting updates about these particular Mundorf Supreme Oil vs S/G non-oil caps, found this. Heat is definitely an issue with my tube amp with 12 output tubes and 4 pre-driver tubes. Runs hotter. This was on the Dynacotubeaudio forum from a few years back. A member in Germany worked directly with Mundorf on this inquiry. I’m sticking with the non-oil Mundorf EVO Silver Gold cap order. Similar to SIO caps. Still running copper oil caps in my tube preamp though.

re: Tube Amps, quote -
"As far as the SIO caps are concerned the max recommended ambient temparature is 70C degrees celsius. That does not mean they immediately die if it gets hotter. They used to be higher (85), but were reduced as they leaked oil in some rare cases, especially tube amps (the viscosity of the oil changes with heat). They never were rated at only 50C degrees.

The Silver / Gold ones are ok up to 85C degrees ambient temperature.", unquote.

Receive the Silver/Gold (non-oil) caps. They are smaller than I expected. Gold wires coming out.  Waiting for my tech to do install in a few weeks. 

Update on Consonance M800SE Monoblocks with ClarityCap MR's.
I have close to 100 hours on the ClarityCap's. I find them dead neutral. They don't add or subtract from the source material. I have updated the power supplies to schottky diodes, kiwame resistors & double the capacitance on the - bias. Also changed resistors to Mills 5 watt for the screen grids & cathode bias. Added diodes to screen grids. These mods made huge difference in detail, soundstage & clarity. Its like a veil has been lifted. Next I am going to try expensive Audio Note Tantalum resistors for the grid of the output tubes. These will replace Russian MLT 5% resistors. I hope they will be worth it.

That is exciting stuff hifijunky! I haven't tries the audio note resistors but really like the kiwame's. Please keep us updated on how it sounds. 

I installed Audio Note Tantalum non-magnetic new version resistors in my left Consonance M800SE Monoblock. I replaced all but two (value wasn't available). For those I used Takman Rey resistors. Total of about 15 resistors(30 total ouch on cost).The right Monoblock still has the original Russian Metal films. Great having monoblocks so you can compare. Checked volume with sound level meter and found it was 1db lower on modified Monoblock than the right one (after every mod I've done the volume is alway lower). Adjusted level on Herron Preamp 1 click to equal.
Modified Amp sounded dull and lifeless at first. After about 15 hours much better. Warm and very detailed. Unmodified Monoblock is brighter, sounds like a transistor radio in comparison. Maybe that is too critical, I like the modified one better. Metal films are known for being bright. Now I'll have to put 6 hours into updating the right Monoblock.
Note there were 2 upgrade kits available for the the DIY Audio Ella amp (same design as the M800SE).
Level 1 was with Kiwame resistors. Level 2 was Audio Note Tantalum magnetic resistors. I am not sure what type of resistors were in the original non upgrade kit. Maybe the Russian MLT's. That is why I went for expensive Audio Note resistors. 
Anyone near Bergen County NJ and what to hear the difference let me know.
