Coupling cap upgrade for Cary CAD-805C help

Hi all,
Here is what I found in this forum
1- Veteran member Brf preferred Mundorf MCap® Supreme Silver & Gold & Oil
2- Casouza stated (mine has only one 6SL7): Coupling caps are tipically .1uF to 1 uF, 400 or 630 Volts and are connected between plate of the first tube to grid of second tube and so on.
I believe your amps have one cap between first 6sn7 and second 6sn7, another one between second 6sn7 and 300B, one large cap between 300B and output tube.
This number match with CaryAudio web on 805AE
Based on statement above - my amp has only 2, but second one between 300B and 845/211 has larger value?
Rodman said 4 ?
BTW: My brother did upgrade his SLI-80 thru Cary and Cary folk recommended/installed Cardas cap over Jensen Oil (same price)

Oh lucky me :)
I found this exact model schematic service manual online

Thanks

Sorry to have confused you. My Cary monoblocks are not 805's, and have four 6550s each(push/pull amps), hence: two coupling caps each. The Deulands are available(discounted) at Parts Connexion. The only caps that are currently regarded more highly, by those that have done extensive(and megabuck) listening tests, are the Deuland Cast-PIO-Ag. Your amps should have 4) 1500uF/450V filter caps, each. I usually buy my bigger electolytics from Digikey or Mouser. They are both very finicky about the manufacture dates of the caps they sell.

You must have hit ENTER, about the time I did! BTW: as wonderful as the 805C is; it would be a shame to use anything less that a REALLY superb coupling cap. According to the schematic; both SET tubes are using a .22uF/450V coupling cap. the final output tube(845) has a 2uF cap, in parallel with the .22 oil filled. You needn't worry about the, "eye" tube(obviously). If you upgrade those .22's; you should realize a substantial improvement(ie: soundstage/more organic sound/cleaner & more extended high freqs, sans stridency).

Really appreciate your comment Rodman
So the 2uF cap is not benefit from upgrade?

I can go with Duelund (price wise) if I can find feedback about it on coupling function. I had my Merlins upgrade to Master status with Duelund caps

From schematic, I have no clue which power caps to upgrade.
Anyway, my goal is coupling caps, as Cary offer
Thanks
