Cary SLP-98L DC or Cap Upgrade details

Ok, I know it's been discussed before but I'm really looking for the details in this upgrade to the SLP-98. I've read direct coupled, F1 upgrade, cap upgrade etc...Now can anyone tell me in detail in what each of these mean and what parts/values go where in the unit itself? I also see various cap values in the upgrades in different units, what does that mean and why do I see these Mundorf SGO caps in various units be of different values? Any help would be great appreciated!

IIRC the direct coupling on the older version (not sure about new or if anything changed since) preamps potentially eliminates any capacitors coupling the gain stage tube to the driver tube, and the output capacitors would remain - but don’t quote me on that. Worth having your tech check inside.

Oh, btw the Greyhill switch shows as standard on the current site notes, not sure when that started as standard on new units, worth checking yours to see if it has it already or not https://caryaudio.com/upgrades-and-modifications/

I do know that we can’t just remove the coupling caps without modifying other parts of the circuit to accommodate this mod. That’s the part I’m interested in knowing, what is also modified/changed when removing those caps AKA Direct Coupling?

I have scrubbed the internet and can not find out for the life of me what is truly done for the DC version.

If anyone minds, could you guys please post a picture of the F1 upgraded version and a "Direct Coupled" version if you have one. Maybe looking inside will help a little bit?
