i love vinyl of course, and for years i’ve been experimenting to produce a phonostage to blow me away. i found a tube stage wite an extra quiet fet input with a partial RIAA correction eq. it was chilling clear bright and then added a beefy low bass transistor eq stage that brang the curve to within a bees dick of a true flat riaa response. took ages to get right. and the result is so fat and clean that my records seem like new again. i’m hearing fresh detail and beautiful depth . i’ve added a transistor neveish stereo HF LF equaliser with selectable freaking ranges and a output stage with metering . and a stereo line input. sheeet. this is going to be great. im building this first unit into a lovely old tolex covered plywood case.
here’s a ‘blueprint’ made today to layout this amp before i drill and stamp a panel. 8 channels in 3 rack units with a headphone monitoring function. the mic amps are 3 stage neevers. the first stage is two controlled amps in series. so – given a soft instrument requiring a big gain – there’s a mile of fat juicey level with low low background noise and low low distortion. each amp is working only a bit – no stress or strain. loads of headroom. andrew tested this neever design against several other high end mic amp amps and reckoned this one sounded the most real and clear and lifelike.
the newest ekadek stereo recording mixer build. 8 mono channel input – two further stereo inputs. there’s a pair of mike amps and a pair of germainium amplifiers too. two fx sends per channel with individual go switches for awesome play-ability. a pair of mono subgroups and a stereo mix bus of course. a full control room section enables complete studio and mixer monitoring . and processor insert abilities over all the inputs and outputs conveniently arranged in one row of top panel socketry . this ‘ rolaphon ‘ contains 38 transistor neve-ish amps and will fit (shoehorned! ) into a lovely old tape recorder cabinet. the rolaphon opens up like a chest. plenty of expensive goodies in there.
ekadek neevatron. here’s a drawing for a new six channel microphone.direct amplifier .
the guts of it is three of the last (in the world) five NEVE B535 dual line output amplifiers – n.o.s original right out of the 1970s – another world.
the neevertron features real simple functionality. mic pad – phantom power – phase changer - fantastic clear sound.
there is a negative feedback stage gain adjusting control which allows to set how hard the preamp works on the input signal.
the output signal volume control chooses off a good proportion of that and feeds the totally juicey B535 line output amp.
an uber fat lo lo Z isolated balanced output is fresh made.
this is a new thornophon mixer build part way.
he’ll be an 8 channel stereo mixer.
line level input with fader.go.pan.
+ echo send
+ 4 other stereo inputs
- also a single neever microphone/di recording amplifier.
- also a 5 stereo input control room monitor section with stereo.reverse.mono.left solo.right solo.speaker a.b.c.
all up a pretty powerful tool made to last .with 100% classA transistor amplifiers for maximum fatness with minimum puss. a big clean sound. and in a beaut portable cabinet. it’s made to be configured as a studio mixer and controller. to receive and mix a sound card’s multi-track outputs, and make there signal currents into a perfect new stereo thing.
it’s a smart little bug!r . can listen to and switch compare all the musical stereo sound outputs u know u need to.
select the MIX output OR external stereo inputs (sound card monitor outputs) E1 & E2, OR check/listen to the neever mic amp or the echo send. throw the sound around to check stereo – reverse- mono. left right solo. and then control 3 pairs of monitoring speakers in a studio.
another awesome day at the office with the best electronics machinery . that helps you do better at what you love doing the most. no o… i mean - making real fat mixes.
manual mixing with a panel of sliders and pans is the best method to balance a mixture of sounds. when u can move two or three faders at ONE time .. u can find , and then fine tune resonances in the harmonic structures of the sounds. extracting more peaks and valleys. adding life. finding those parts gets to the spark between the instruments. the distance between things locks in.
a computer mouse can move one fader or click one button at a time. what the hell use is that? ok . so u have a computer fader panel .. and then ur still just inside the box. and i reckon the mixture sounds better done outside in a real amplifier mixer with faders , and outboard special fx and maybe even a room mic. give a poor computer smacked up thing more oomph - driven energy.
off to the big smoke tomorrow . this new roger 3 ways very flash all transistor dual channel eq. features
neve 1081 style 5 frequency high and low frequency control stages. very fat and sharp . for a deep deep sound. teamed with a freaked out sweeping midrange stage. boost or cut 200hz – 6Khz he has double series band pass filters for a tightest Q potential. with selectable band pass gain effects .
1. normal NICE and clean
2. sharper q Q.TIGHT
3. turbo sharp INSANE
hook this baby to a mad playable keyboard and a echo box and u could have a mother of a synthesizer sound. learn to play it like one thing and freaking shit. thats a real human electric direct sound! right there. one take. the circuit board contains cards of electronics arranged as two in line channels. left to right . treble – midrange – bass – output. each stage contains perfectly simple fat A-class inverting amplifiers made of just four transistors. no chips. plus. quite a bit of specified frequency selective boosting cutting circuitry is in there on the mother too. . it’s the prototype to a unit that can make a few of. or maybe a more largess thing for DJs .. that item would need preset-able fitments and lets make it xfade-able thru a delay effect loop. to create some very far out transitions. the all transistor circuits make it clear and fat and low low noises with richness and real balls.
