phonoekagrapha is alive

phonoekagrapha

new phonekographa build half complete. two stereo tube phono preamps -  crossfaded onto a stereo bus. 2 other stereo line inputs and a mic amp also feed that stereo bus. the stereo bus can get eqed and metered and set to feed 4 stereo sound system zones. zone 1 is a two way split up system – sub and fullrange.  u can use the stereo cue /headphones function to listen to any mixture of the 5 inputs pre – stereo bus.. so as to attempt to get it right for a change. u know who u are…. anyways … the tube RIAA preamp and the neever transistor amplifiers (40! inside there) sound freakin awesome.i played  a top ‘o’range pioneer mixer against the phonoekagrapha  and !@#$ .. astounding change in clarity and depth of sound.   this beast is for installation at CONCH RECORDS . hi fi bar. ponsonby .new zealand.

phono roger eq one

ive been experimenting with a valve mag phono stage for a while and have at last nailed it. the mysterious circuit had suspicious boobitraps and ommisions, pfff.   i think by marrying it with the fabulous roger eq one …  your record player can  now drive a truck!   so fat and powerful.  u can pop your boat and caravan on there too. i’ll make this one into a beaut thorn  mk12 tape recorder cabinet over the summer . that  understated grey vinyl covering is a perfect foil for the bright electric valve sound about to be transplanted in.

new product . ROJER EQ1

here’s a new twin channel rojer eq .  a drawing for a new build for an old client .   the 2 way valve eq design was inspired by an american rogers hi fi amplifier that i repaired years ago.   sounded  ahhmazing .. such a really clear sweet hi freq and fat low tight bottom end. and with some ekadek tweaqs and refinements – even better.  the size of the sound adjustment  is impressive. a vast tone and body control. go subtle and careful with a mix  or slash and bash a single sound input to pieces. the output stage is the  big pultec MB1 . all in all an eight tube box. kind of extravagant?  you betcha squealing piggy banks its extravagant. roger is completely worth the 3500 nz$ – every buck. he can build  or bust mountains. sort the trash and make cream buns and make glass shatter . he’ll do the dishes and never answer back. and who doesnt want that in their crew.

skyqueen pultec MB1 tube preamp

this EVER READY SKYQUEEN  is straight out of the 1950s. shes been (tenderly) gutted and had a beaut pultec  MB1 design  two tube mic/direct preamp built into her.
the 1/4″ direct input is a tough sounding hiZ instrument amplifier,
super great for direct bass guitar or keyboards.

the microphone input is balanced low Z  with switched  phantom powering . she uses an american edcor input transformer with custom sheilding.   the  pultec MB1′s custom output transformer is made from the highest quality japanese grain orientated steel. this improves the low low bottom end signal integrity.  xtal clear and solid bottom end gives an amp the big dynamic smack ability.

the stereo 1/4″ input  has a left/mixed/right signal switch.  -  matches from a media player whatsit. ipod or cd payer. sounds awesome – the valve amp gives that signal a very much sweet tweaking.

she also has a tube  P.A  stage to drive the small but fat sounding internal  speaker.  or headphones.  the p.a amp isnt a powerful one, just 1 or 2 watts of valve radiogram style.
the skyqueen has very desireable looks.  with creamy aligator tolex vinyl covering and brassy trim bits. she has a fancy – and so modern perspex handle too.  i hope the photos taken in the lovely matamata early evening light  do the skyqueen some  justice. she really is  unique.  weve been soak testing skyqueen day and night just playing cds thru her. wow . so good.

skyqueen in the bath

the skyqueen’s panel and sexy knobs are off for their annodising bath. shouldnt hurt a bit. i dont really think that the panel is going to come back quite with so much  uranium tan or anything like the above shot. we’ll see what advanced anodisers in tokoroa can do with it eh.  anyways in the midst of all the other secret work … the skyqueen is almost alive. ive changed out the  5 inch round celestion speaker for an australian rola ‘c’ 5″X3″ original 60s unit. the sound has superior bass punch and flatter top end zing now.  for sale soon at 1500nz$  +gst  for the skyqueen MB1 tube preamp and speaker/headphones playback amp. in a beautiful small textured vinyl covered plywood cabinet with very curvacious perspex handle.

philip ontop the heap

geez. philip has some fine company there. damian is up to his neck with  united audio la2a. wunder audio and a manley vox box. philip has been in our family along time scrapping it out with the odds and bods around the place. and getting lent out a bit to friends.  the wife and kids will miss this handy little fine strong sounding tube mic di preamp. not to worry . he’s gone to an appreciative home.

Hi Ek,
Sorry about the late reply. I have Philp at home and have given him a good workout.
Wow! Very smooth and quite open sounding, it smoothed out any harsh plucks of my
acoustic and rendered a real balanced smooth tone.
I actually liked it more than my Manley Voxbox in this instance! In the end it was a
hard choice between my Wunder Peq2r and Philip, they both were great in different
ways. Anyway I just want to let you know this preamp represents pure tonal bliss and
at the price I got it for it puts some of my other pre’s to shame ;-)

nominee for ugliest amplifier in the world

so far the  MB1 amplifier (12ax7 & 6aq5) and the small speaker power output stage (6aq5) are built onto an ugly custom stripped out chassis. its chopped up  to  fit neatly into the lovely old skyqueen cabinet.  it sounds great even with it’s very temp/experimental control  wiring. just need to  drill and letter stamp up the panel, anodize it.. and finish the build. the ugly chassis looks like many  50′s european radios . those crazy germans made the ugliest most dangerous looking electronics   …placed  inside beautiful veneered plywood cabinets. u just dont see  that stuff being made anymore. if anything has curves -  safely assume it is moulded plastic.

ferralgrapha results are in

alex got back just today. he is loving his system i reckon. p.s. The Ferralgrapha is bloody excellent mate! I’ve done two recordings so far and even been trying it out in live situations. It treats everything so beautifully! Been getting some really luscious sounds with it. When i have some mixed examples i’ll write you a proper review for your website – with a link to a recording, so the people in internet-land can hear the magic!
thanks alex.  meanwhile i’ve packed up and moved my tons complete with wife and children to the country. we’ve wanted to do it for ages and have at last made the shift. so ekadek has a new lab  – well , two actually. the end 6 feet of a largish shed overlooking a pretty backyard. and a tall workstation in the living room beside the fire.   far from the agrovated noise and relentless bustle of the big smelly expensive city. everything is so different down here. the air – the vibe – the smiley happy to help locals. a great change for the family and for ekadek to hunker down unhindered by the stinky taxing city and soon to stride out with some awesome new product designs. matamata is a great little place! it is situated in the centre of a large farming district so theres a lot of small efficient industry here.  and a veritable heap of creative folks doing their thing without worrying too much about keeping up with the joneses.  its most famous attraction is the ‘lord of the rings’ hobbiton film set.  it really is beautiful down here – idyllic.  just like the movie.  we are renting a  nice small house within matamata  town for a few months while we settle into work again and take our sweet time to find and purchase a property out  in the countryside proper.

one live ferralgrapha

the ferralgrapha has passed all the tests and has left the building.   wow. he  is awesome so so sweet sounding. the mic sound is fat .  clean and solid.  50/150/600 mic balanced input types make for very useable tone variations with any mic.   the special extra  amp stage gets very miles of gain for the ribbon mics.  the eq is tight or deliciously wide. very flavour enriched. wow,  it sounds so so alive. im hearing my records for the first time again. theres a weird effect with good tube circuits – suddenly the music just really feels like something again. just so big and warm – all the soul regained purified of any digital scurge. and the very back background feeling gets clear. my freakin spine is tingling. thanks alex for letting me build this. man u are going to love it. your stunning microphone collection will love the ferralgrapha too.

ferralgrapha is building

ive drilled up the panel and letterstamped it. it’s been  bent   to fit the cabinet properly and is getting anodized as i type.  while it is soaking  .  i’ll finish and test  the tube chassis. 8 tubes . 6 signal transformers. my evolved prototype chassis sounds great – really open feeling microphone sound.   the tube amps – the very flavorful equalizing  possibilities -  and the in/external monitoring functionality make the ferralgrapha a complete one machine for studio or live recording sessions.

new ekadekatron model

the ultimate & uber non portable 16 channel valve amplifier. after a fair while drilling every holey hole – it took only a day to final construct these 2 basic chassis skeletons. milled & cut & folded 2mm aluminium custom rack mount trays-  32 valve sockets – 16 tag strips – eight threesomes of hi voltage caps -  saddles of input & output connectors – 16 of  MB1  16k/600 output mofo trafos – and  obtusely massive  power connectorators .  this build is well underway now . it was a good day.
