SSL G series parts query

been completing my materials list for my first build of this and have a feq questions.

the first is ref the semiconductors.

for a few of them, the NE5532, TL072 and TL074 there seems to be multiple designations (letters after) does it matter which version i get, anyone got any ideas. its more straight forward if i go with alternates LF353 and LF347 however are these as good. will i even notice any difference.

also having trouble locating 33pF and 6.8uF 35v tantalum caps. i'm in the UK so if anyone can shine any light id be most grateful.

maplin dont seem to do them and neither does RS

6u8 262-5055
33pF 829-277

thanks for that rob,

id been looking through but couldnt find.
i actually rustled some up on farnell but since im already going to be getting my vu etc from them that will really save any hassles.

any thoughts ref the semiconductors (op amps)?

..you'll want normal dual-in-line versions (not smd) - other than that, any version should do..
