Retro Radio Mic | Micron TX503

[@TheBilico86]

Só de olhar esse modelo de microfone, dá uma nostalgia.

[@RetroWorkshop]

é um design clássico

[@kevinsleach]

I enjoyed this. Very impressed by your attention to detail.

[@antoniobasiliobrito]

I love this microphone. Here in Brazil, the Globo TV use it a lot ... in the 80s and begining of th e 90s

[@RetroWorkshop]

Yes I have seen this mic is famous in Brazil!

[@julianpilfold-bagwell1923]

Holy crap. I made the RF front ends and antenna distribution modules for these. Also worked on transmitters, mainly RF output. So happy to see this. I have a tx101 and matching receiver as well is you're interested. Not for sale, but if you wanted to have a look I can go with it. Odds are, if you open the receiver modules up, my handwriting's on the crystals.

Julian Pilfold-Bagwell Great work on this kit Julian. Beautifully made inside and out. I just bought a TX203 and had a peak inside that. Interesting to see the evolution in components. I also bought a VHF TX503 with silver capsule. Drop me a message via my website and I’ll get in touch. Retroworkshop.uk

@@RetroWorkshop Nice to hear. QA was really hot there. No batch testing, every board individually tested, heat cycled and zero tolerance for for minor errors like the surface of insulation on wires being even mildy affected by heat guns when shrinking sleeves. I re-read your write up and your unit was made about 5 years after I left but it still looks very familiar.

This is magnificent! .. my friend was a sound engineer for the BBC ... (retired now) ... I bet he saw a lot of these ... great video, amazing detail, this must have taken ages to produce and edit! Excellent explanation of multipath radio wave cancellation! Great work!

[@DubiousEngineering]

Hahaha... that’s retro man cave voiceover

[@RetroWorkshop]

Thanks Howard. I bet your friend had come across these mics as they were very popular at one time. Glad my multi-path explanation was understandable! I always think a video will take 2 days to make, then it ends up taking 2 months.

[@julianpilfold-bagwell1923]

Yep, BBC was a major customer. From what I remember, Neville Druce who was the joint director and head designer, had been a BBC apprentice before he started the company.

[@peterbridges1103]

Brilliant look at a great piece of broadcast tech. Really admire the attention to detail you gave in restoring this kit to its former glory... and what a testament that it still works and sounds great.

[@RetroWorkshop]

Thanks Pete. The kit is available for hire if you need it for a job 😉 You may struggle in London on channel 28 though as Crystal Palace has a multiplex on there unfortunately.

[@techgroundingtv1421]

Hi! Thanks for the video - very nicely produced with clear audio and no distracting muzak! I've got several of these with portable diversity receivers and I use them daily! I used to use them when I worked for the beeb in the seventies but never thought I'd be able to afford a kit or three. I'm trying to get hold of a TX203 at the moment to use in addition to my personal mics.

Microfone da Xuxa!!!!

[@xyzt-kd3zn]

Exactly!

[@TheBilico86]

Era também o padrão da Globo na época, só de olhar, queria ter um, mas achei raríssimo.

[@leandrosenutna]

@@TheBilico86 exatamente, (padrão não só na globo como mostra o vídeo) estranho ter sumido, eu gostaria de ter um mesmo que não funcionasse

[@antoniobasiliobrito]

​@@leandrosenutna sou apaixonado por este microfone...

[@leandrosenutna]

@@antoniobasiliobritoainda não consegui descobrir onde consigo um 😂

[@RMCRetro]

Wait hang on.... was that YOU in the Big Breakfast house!!!??

[@RetroWorkshop]

It was indeed. I was needed for an inspired item called "Around the House in 8 Daves". Harder than you think to get 8 people called Dave together with 24 hours notice, and convince them to be in east London at 6am.

[@dafoex]

@@RetroWorkshop You missed a trick: "Hey Dave, what's your name?" "Geoff"

[@Josh-wu7kz]

I can’t believe you managed to find a rack mount micron receiver, I’ve got a couple of tx503’s and use a 19” rack for my sound equipment but the only receivers I could find for them are like square boxes that I can only use externally from the rack and need separate power supplies so they take a long time to set up when I do live sound work. If you were ever interested in selling the rack mount receiver please let me know as I will pay whatever you are asking for it within reason. Kind Regards, Josh.

[@RetroWorkshop]

Hi Josh. Drop me an email (you can find this on my channel page > About) - Dave

[@nickshipway8199]

I know this is a few years old, but hint for cleaning up anything with gaffa marks, or sticky residue is eucalyptus oil. It cuts through so many of these things.

[@RetroWorkshop]

Great tip!

[@ignacioguillotine]

Micrófono de NUBELUZ ( las dalinas)😍

[@RetroWorkshop]

Yes it seems this microphone was very popular around the world!

[@ninjabluewings]

VERY VERY INTERESTING! indeed, what does it sound like?

[@RetroWorkshop]

Very good. Check out 6’18”.

Where can buy this mic?

[@RetroWorkshop]

Keep your eye on eBay although many are old and may not work, and the frequency may be unsuitable for your location.

[@vann90720]

Did I see that right? You spray painted over the mic head without first removing the capsule and surrounding foam? /cry

[@RetroWorkshop]

Yep, you saw that right. A few microns of paint won’t affect the sound penetration. Don’t forget most users stick 5 to 10mm of foam over the top by way of a pop shield. I tried to extract the capsule from the mesh but the rubber seal was stuck fast and I didn’t want to damage it. And as you can see it looks much improved afterwards. But thanks for your concern 😉

[@Bikalakat]

@@RetroWorkshop man, I dont think I can provide you with accurate data, and I'm not sure if youre refering to the mash, or the membrane, but hell, no, I dont belive a few microns on the membrane wouldnt affect sound, after all, the membrane itself isnt a very think (or heavy) piece itself, and it has to stay flexible, it is obviously the most sensitive part of a microphone, saying that painting over it wouldnt affect perfomance is just insane. Of course, a few microns of paint on the mesh is not a big deal, we're worried for the membrane. Mentioning acoustic foam is irrelevant, it ment to keep low freq pressure of of the membrane, but it doesnt touch it, or anything.

@@Bikalakat oh sorry, you’re an expert are you?
