Quickie cap upgrade

Grainger,

Is that the same as the K72's?  They are fairly cheap on ebay, what would that do to the sound?  Maybe .02uF would be good?

Sorry, yes.  There are a number of KK Teflon configurations.  There are K72P-6, K72P-3, K72-11, FCH, FT, FT-1, FT-2 & FT-3 (some say the best sounding).  There are a couple of others you want to ignore; the "Doorknob" caps and the K72-8 with antenna connectors on them.

Some have studs, some have leads and some have the tabs on the end.  I think the differences happen with value (uF) and voltage ratings. 

There are a lot of variations out there.

Wow.  I had no idea there were so many.  So the preferred cap is the ft-3?  The only question is which cap to pick.  The cap selection is subjective (ideally if someone had the same piece of equipment as you and had similar taste in sound they could recommend a value (at least that's what I hear from the Bottlehead folks!)  Anybody out there tried a bypass on the quickie?  Experimenting with these buggers could be a very time-consuming hobby, since teflon has a 200 hour burn-in    I'm pretty impressed with the sound of the k75 by itself, but you never know when the upgrade bug will strike, so this would be handy information to have!
