AOS Exclusive Review of Eco-Fan Sound Pre-Amp and Power Amp

[Spectral Morn]

...

an ecofan brand radio - would be very
interested to find the owner...


...

Attachment 15215

I didn't know Murray had built a tuner, I am sure that's very good. If I had known.... sigh.... I would have asked Murray to build me one.

So many regrets re not getting Murray to do stuff. My biggest is the interview I tried to organise that fell through, he just didn't seem that interested in doing it.

hi all,

barry: i zoomed in on the original scan to see
if there were any distinguishing features on the
garrard's tone arm - sorry can't i.d. it...

walpurgis: murray plinthed a whole series of
garrards and connoisseurs in the '80s - there
were still a few in the storeroom when we
tidied - garrards went to keen locals and the
connoisseurs are still in storage

dalek s: an interview would have been great -
murray always proud of his gear but oddly
reluctant to have hifi conversations all the same

there are still about a dozen preamps from the
90's ready to assemble - both 'ten tubes' and
'phono eq twos' - all the casework and modules
are complete - need only final assembly and
power supplies... if anyone is interested we can
look in to completing some - there is still a top
notch transformer winder here called brian smith
- lives in a town called foxton - well regarded and
very decent chap with it - let me know if fancies
are tickled - pictures attached,

kind regards,

adam

hi all,

i watched a fascinating talk by
david huron - the author of a really
interesting book on music and
cognition called 'sweet anticipation'

video link below is to a talk he gave at
a conference on music and the brain
in santa fe last year - mostly about
why music gives listeners 'goosebumps'
but also happens to describe why the
big knob on your amp is labelled 'volume'...

kind regards,

adam

hi all,

am pleased to report the delivery of
the new 60V transformer from marque
magnetic - significantly smaller than the
last 120V unit - 50mm x 50mm x60mm
- hope to have new 'lash-up' by next
weekend - pictures to follow,

kind regards,

hi all,

happy to post picture of latest
'lash-up' of the ecofan boost-it

bigger caps and more filtering
in the new supply board - new
stereo valve 'module' - and of
course new power transformer

more work on power supply to
come - hope to post an in-box
version before too long

here's a link to the magazine
beneath the lash-up - good
coverage of nz music - also
good columns for players:

hi all,

mike m spent a pleasant day going through the ecofan
circuit book yesterday - could be time to make an amp

would anyone be interested in sponsoring an amp build?

we have sets of transformers for a number of amps that
could be constructed - most keen to complete a seotl and
a bsea - let me know if it strikes anyones fancy,

cheers,

adam
