I've used:
- 100uf 25v caps
- 10uf 50v caps
- Q2: Couldnt find 2n5088 and tried "BC239" and "2SC1815" but didn't work.
Has anyone tried this layout? Is it really "verified"?
harald has a very good reputation re his layouts. i would initially assume he wouldn't label it verified unless it was. had a quick look at the original page and notice freppo (who posts here) also built it with success, and he also knows his stuff. worth checking the original post for any updates or mods to the schematic just in case it has any idiosyncrasies.
http://www.sabrotone.com/?p=3186http://www.sabrotone.com/?attachment_id=3185and back through this thread in case subs for 2n5088 are suggested for this layout.
but i would say get some 2n5088 transistors (as specified by the layout's designer) before suspecting the layout might be out. i know it's a drag when you want to build and not wait for bits to arrive, but if it was specified as 2n5088 i would give that a go first.
i think all your caps should be 16v+ (as specified) if you intend to run it up to 18v. i haven't built this but have i built the ep3 18v pre at guitar fx layouts, but they are two kinds of the same thing (echioplex 3 pre).
good luck with it. they are nice things.
