By the way, Andre, thanks yet again for the 417As. They are now about to
move from potato amp status to SET drivers. I think would like a little
more power. I've just got a pair of FE127es to play with and have been in
mad box-building mode. :-)

My pleasure, Mick. Did I somehow miss the thread in which you told us
the design of your potato amp? And, of even more interest, the
speakers you used them with.
And what the devil are FE127es? You're getting weirder and weirder
Mick; soon you'll be insisting tube rectification sounds better than
than those square black thingies lying dead with their legs in the
air.

Its strange you should mention potatoes in relation to tubes.
I used to use boiled potatoes as my secret weapon in bike races over
100km.
They did seem to work better than a Mars bar.
Mars bars are rubbish. The lift doesn't last very long. What works is
carbs. I carry a packet of fig rolls on my bike; highly recommended by
the coach of the British mudbikers. When I was a rugby player, the
team diet was fillet steak and all the potatoes you could eat.
Inevitably, I collected the name, Potato Pat, and I didn't mind.
I had the full license to use potatoes winningly as I wanted.
Why now, I was tree quarters Irish, because of me Irish mum,
and because of me dad, two turds English.
Well now, Padraig...
And now, yeah, what is an FE127?
Are they not Foster five inch drivers?
Yeah, I shoulda seen the clue in Mick's "mad box building" but I took
that to mean he was drilling a chassis for these weird FE127es
tubes...
Fostex, eh? I heard about them: Japanese-style Lowther type point
source speaks with whizzer cones. Said to be very nice indeed in
tapered quarter wave pipes. Indeed, I once published a design that
could be used interchangeably with 8in Lowthers and the equivalent
Fostex drivers, with someone reporting on the single driver conference
that the Fostex went a bit deeper in my design than the Lowther.
Personally, I hated the design, because with the Lowther it was very
sensitive to just how you stuffed the area behind the driver,
otherwise you got a screechy treble overwhelming everything, which had
to be fixed with stupid little tufts of wool between the whizzer and
the main cone; I hate that sort of kludging, and don't care overly
much for those who try to promote it as "tweaking". In my Fidelio type
horns the Lowthers work without that sort of messing around; of
course, my smallest Lowther horn has four times the footprint of a
TQWP, so there is a certain wife acceptance factor involved for the
young at heart.
What sorta boxes did you build for the Fostex, Mick?
