” I am listening to your phono stage now. It really is something very very special. I thought my !@#$ was good but yours just blows it out of the ballpark”. ..(nathan haines is auckland/london based jazz musician/composer)

a turntable (MM cartridge) plugs into the phono inputs and a computer/cd/tape/mixer/whatever can plug into the line inputs. there are adjustable gain stages for the phono amp channels – so to pick a gain factor that suits the level of the record. some records need less gain to get in focus – some need a bit more.

there is a smooth rotary cross fader control to select between the phono or line to mixture into the EQ amps, master output amps, and xover . plug a good mike or synth or any instrument into the studio preamp – lay an effect in it  with it’s insert function and mix it with the phono or line input.

also send the mike/di and the phono/line sound out to an  effect processor – bring it back – mix it  in.

wear headphones 1/2 on to look cool . and  to 1/2 listen to any sound selected audio source in order to sort a cue point or check an incoming level. also set the meters to your preference – maybe even turn them off – go commando.

this preamp is set up to play directly into a power amplifier-speakers/powered monitors – set those to go loud and then use the phonozoopa master to set your room level.

i’ve not been audiophiliac / minimal with this design. there’s all sorts of adjustability going on. because. every record has been made up – played – recorded – mixed – mastered – cut and sold up by THE craziest obsessive bunch of mother!@#ers ever . u know it. so the phonographa (1080 neve-ish) eq can help sort it out . taming a potentially scratchy top ended so as to tune up some to feel the sound fill a room without harshness that will kill your concentration. sometimes a record might love a mid top end 3khz shelvey kicker . or a 12 khz sizzler. and hell . the bottom end might need some deal of massage too . the 50hz and150hz shelves can save a thin record from itself. the wide low middle end adjustment is like a heater warm&friendly setting. the very careful listener adjustment of the two controls and two switches is definitely worthwhile. yes.. the production of LP records – and big fat hifi sound tone adjustable systems were made for each other . so ive made an eq that can peak for the clear listen and experience – only so to enjoy it even more.

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.

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 ferralgraffa studio unit

an australian  client has ordered this stereo MB1 chassis  – versus  -  my sweet lady tube 2 way EQ . a great combo  .  he has supplied a beaut old ‘skin’ tolex covered ferrograph tape recorder case for it .  so im going to make this stereo mic/di/eq amplifier into that -  complete with on board 5 watt tube amp and the original 9X6 inch goodmans monitor speaker.   the new dual pultec MB1 tube mic  amp will  have variable input impedance. 30.150.600 ohms . alex has some real old ribbon mics .  and wants extra tonal front end augmentisation capability in general.  the big old meter switches between the two preamp outputs.  as does the EL84 single ended tube P.A. amp.   the 2 way tube equalizer  features as the MB1 alternative input source.  reverse engineered design from an american roberts (or rogers) stereo system. a unit that i repaired once really impressed me. the eq sound was so fat and deep. a very particular circuit built around the feedback of a single valve amplifier stage. ive added a preamp stage to it to enable an  effective rumble filter,  and hi/lo frequency switches to the bass and treble stages  to complete this massive sounding 2 way eq adjustment scope of this ferral graffa transportable 2 channel studio preamp unit .

new sweet lady eq

i already make fat ladys so why not ? but i reckon the product is just so cute and friendly.  not so little at 3ru this single (or stereo) channel line equalizer features  a trafo balanced input .  tube driver . bass -  treble frequency switchable shelving eq with and a fat two tube MB1 balanced output stage.  one sweet fine lady .
