“gidday! How are you? Just wanted to let you know the kaimaitron is going strong. Really getting to know my way around it now. It’s really amazing how many different tones come out of this thing from clean and clear to fat and warm to fizzy and aggressive. I’d still like to get the germanium stage up and running but even without it this thing has become a centerpiece and I’ve done everything on the new album through it. Apart from the beautiful quality of sound in itself, it’s also a very unique sound. What’s the latest?”
many thanks to ruban from U.M.O for those words.
ekadek klangenschmitt spitfire console design.10 channel transistor mixer with stereo bus and echo bus.
stereo valve eq. stereo varimu tube limiter stereo tube mix bus amplifier. 4 stereo returns. control room section has 3 speaker amp outputs – headphone send selection and volume , talkback function. an onboard p.a small fat hifi speaker is on board also. and big meters. 23000nz$ ballpark.
bevan from bagnall hill studio in country te pahu has just completed his trinity rack. contains three choice ekadek builds . on top is the dual channel 535 neever mic di amp .has original neve 535 twin channel awesome transistor amplifiers. in the middle is roger all tube dual channel mic di equalising amp. and down below is the four channel all transistor neever commando mic di amp. bevan has a big recording space out in the country side that he built himself. genius. he also makes guitars and ukeleles out of juicy native timbers. boom! double genius. check out his CAPTAIN brand. http://www.captainukuleles.co.nz/home.html
rebuilding this cambridge electronic workshop console.
it will be 14 channels into 2 stereo mixes with 2 pre/post aux sends. there is talkback facility to aux 1. there is a small speaker p.a amp on board. there is a complete control section. her he is all taken apart with new and old circuit boards arranged onto mothers – almost all ready to be reassembled and wired . next weeks task.
i rescued this desk in melbourne about 1996 from the infamous RAY EMERY – he was a sound guy of years and years who had a house in the sticks piled high with old tech of all sorts. he was an awesome guy who was very generous with parts and infos and rum. the other desk i could afford at the time was a mackie style . i hated those measley thin heaps with zero headroom and bad eq. i.e no fun.
so i bort the cambridge and a heap of other bits off ray and slowly remade it work and have used it ever since in my studios.
the cambridge is all transistor from around 1975. just before chip amps became normal to use in consoles . i.e the burying the good clean audio signal with multiple multiple stages of chips each with a gazzillion transistors each. those cheap mass produced consoles are major electronic bullshit.
ive never found anyone who has ever heard of the cambridge audio workshop. so this must have been a prototype – originally designed to be a special functional theatre console.
the cambridge transistor operational amps are very neve ish .. 1070 thru 1080 like. the similarity is bonkers. they utilise different sex power supplies and opposite polarity bi polar transistors .. and yet they can live on the same circuit board. it’s a mystery wraped in enigma
this is a five microphone input – one line level output mixer. made by NRU ( Nederlandse Radio Unie ) netherlands in the early 1960s… i think. it was a super high end specicfication /price unit made for any outside broadcast application of the day.
if in NZ … NZBC concert programme recordings i imagine,
right thru to televised rugby matches.
and ‘ it’s in the bag’.
i saw this on trademe a month back. and surprise ! my tauranga client and friend damian lunson got it. so i get to play with it for a while.
so far it seems like the building block 2 tube amplifiers are the gold. there are 8 of them – mostly the same. except their individual input and output topologies are messed with according to the functionality design. 5 are channel amplifiers with switched input mode and selectible amplifier gain. one is a mixture amplifier. one is an output amplifier. one is an afl (cue function) amplifier.
the thing to do is to reverse engineer a module – draw one out – get it going – see how awesome it sounds. get familiar with the rest – draw out an overall layout – test the theory. and finally decide what the freak to do with it.
riaa phono magnetic head preamp. super accurate. super fat and clear. high tube gain with low Z transistor amplifier output.
