I have an excellent Rogue 88 mag amplifier.
Id like to swap out some top notch parts in the amp.
Can someone place me in the correct direction?

On an amplifier built in a PC board, you need to be relatively skilled and confident to properly remove components from the PCB without damaging it. The Rogue boards are solder masked and through hole plated, so that risk is somewhat diminished, but you still need to be prepared to deal with the occasional lifted trace here and there.
With the 88 in particular, the board spacing for the coupling capacitors is minimized because there isn't a whole ton of space. This means that most "upgrade" parts aren't going to fit the footprint, and it will be awkward to install those components. Their leads may also not fit properly through the holes. If you do this anyway, the amp may not be easy to sell down the road if the inside looks unappealing.
Still, the PPMFX caps from Multicap are what I tend to use in these situations. They are physically not very large and their leads are not all that large in diameter, so they tend to fit pretty well.
In a big push-pull amp with a lot of feedback applied around the whole circuit, I find that these upgrades do more to soothe the mind of the owner rather than to do anything positive or negative to how the amp actually sounds.

Upgrades
Yes thanks for reply. Not afraid of anything you mention and have done a few of my own repairs on amplifiers ect.
Rogue audio offers a "Dark" version of thier amps that are probabley upgraded coupling caps ect
No worried about resale value.
Here is what got me started .AUDIO MODIFICATIONS
Thanks!

Yeah, a V-cap teflon isn't going to fit in the Rogue. The leads won't fit into the board, and the weight of the cap will rip the board apart.
Someone who "mods" an amp with a 6SL7 driving a 300B and doesn't immediately get the 6SL7 out of there maybe isn't the voice of wisdom you should be listening to...

Interesting read thats for sure.
Thank you for the input.
Hopefully get a reply from rogue service
