Build Your Legends Series No. 3

The Tube Opto Compressor featuring the legendary "Silverface" LA2A

Ask any sound engineer or artist out there to name one of the most iconic tube compressors ever made – the majority would certainly say it’s the Teletronix LA2A. With its extremely silky sound and unrivaled simplicity of controls it’s the go-to weapon for most engineers when it comes to vocals or bass…

As with other projects in the past, we will again create a ton of easy to understand and well visualized content that will make building this piece of gear almost as easy as painting by numbers.

At the end you will know everything you need to know about this famous opto compressor and – more importantly – how to get this legendary piece of gear in your studio by building one yourself!

Part I

#norocketscience

No more concerns

As in the past I created a video for you as an introduction to the upcoming series. Those of you, who have been around for years now may notice, that I’ve also included some footage from the last series. But I think much of it is extremely valuable for those of you who are (rather) new to analogvibes, and an absolute essential to create a solid foundation for your journey to build your legend(s).

As a professional interpreter, I work on rockets and I deal with precision-machined parts and finishes on a daily basis. The execution (sheet metal bending, cut-outs) and the paint job is absolutely fantastic! Way to go! Your hard work means a lot to us gear heads.

As a long term analogvibes community member you surely remember the last series covering the Tube Program Equalizer aka the legendary Pultec EQP-1A. Back then we asked you about what is holding you back from building your own gear, your feedback was incredible. And it was exactly your feedback that led to this e-paper – an extremely valuable foundation for all those who explore their ways into the DIY world! This one’s for you – from the community for the community!

Part II

#meetthelegend

3 iconic knobs

Still not enough? OK, take a look at our LA2A knowledge base

It’s time to continue the Build Your Legends Series saga!
The 2nd episode is all about the Silver Face Tube Opto Compressor – its history, how it does its magic and of course we all wanna know how it sounds, right!

And because I believe it’s extremely important to know how the gear you use actually works, here’s „The 3 iconic knobs“ e-paper that explains the working principle of an LA2A in every detail!

It’s the second e-paper of this Build Your Legends Series and you can just download it – as always – for free!

You’re welcome 😉

don't take just my word for it

what others are saying so far...

How we’ll make it happen

pre ordering together = GROUP BUY

As mentioned in the videos we can only make a new project happen together – meaning we are going for a GROUP BUY. We have done this several times in the past for all our available projects. It has proven to be the best way to bring these projects to life which otherwise wouldn’t have been possible.

  1. 2015 TUBE OPTO COMP V1
  2. 2016 TUBE OPTO COMP ROUND II
  3. 2016 TUBE PROGRAM EQ
  4. 2016 ULTIMATE TUBE MIC PSU
  5. 2017 TUBE OPTO COMP V2
  6. 2017 TUBE PROGRAM EQ ROUND II
  7. 2017 TUBE MIDRANGE EQ
  8. 2018 ULTIMATE TUBE MIC PSU V2
  9. 2018/19 VARI-MU 176
  10. 2018/19 TUBE OPTO COMP V3
  11. TUBE PROGRAM EQ COMPLETE KIT

Important notes & conditions

please click on them & read thoroughly!

As we face minimal order quantities for several parts of the kit we’ll need at least 30 kits pre-ordered to make it happen. If we should somehow not reach that goal (I really don’t think so) the group buy is off and we will refund the preorders that have already been paid for. 

Global logistics are under great pressure since covid and are only recovering slowly. So we estimate rather generously.

Estimated time depending on your location:
Germany: 4-7 days
EU: 5-10 days
World: 10- 30 days, depending on your location & and on customs clearance.

These are the shipping times only – not the manufacturing lead time (see roadmap below) – just to be clear 😉

If your are located outside the EU there may be additional costs for import duty & taxes.

The HS Code for the Kit is: 8543 7090 ** **** **** *
Best to check with your local authorities. You can also try to check your customs here.

Please note that analogvibes is not responsible for your import taxes and duties.

With your pre-order you agree to opt in to the analogvibes newsletter so we can keep you up to date with the progress.

The already finished e-papers will be sent to you with the order confirmation. The upcoming ones follow via email once the kits are ready for shipping.
We highly recommend though, that you create an account during checkout, so you have all the e-papers in their latest versions – always accessible in one place. 

Roadmap to your Kit

For better understanding & transparency we have set up a small roadmap for you. To be more on the safe side, the timeframes for each phase are generously estimated so if everything runs smoothly we may be quicker. But although we prepared this very carefully, if unforeseen obstacles arise (and experience tells there’s quite some possibility for that) it is also possible that it may take a little longer.

You might also have a quick look at the Meet-The-Legend-Page of the Teletronix LA-2A for details on that legendary piece of gear.

All set? 

Well, then go for it!

We hear you

Your Questions, Feedback & Comments are highly welcome…

For starters we have a few question for you:

  • What are your top two or three questions about building the upcoming Tube Opto Compressor (aka LA2A) that you’d want me to answer in the BYL-Series?

As you know this is an homage to the iconic Silver Face LA2A – how important is authenticity for you when it comes to:

  • Limit/Compress switch:
    on the back = more authentic vs. on the front = more practical
  • Electrolytics:
    big can cap on the back = more authentic vs. modern electrolytic inside the enclosure = cheaper
  • Audio connectors:
    XLRs in addition to terminal strips = much better connectivity in modern studios vs. terminal strips only = more authentic

    Hi Martin,
    Cant WAIT !!!
    Limit compress – i cant decide !!! because its way too Fantastisch !! – you decide for me Martin 😉
    Cap on the back !! 100% – That is the real deal – like an AMG G63 with exhaust out the side – there is NO other option.
    Audio – my 1176’s have both – lets do both. If money or rear panel space is a challenge – my vote XLR

  9. Florian

    The best solution due to practical and functional reasons would be:
    Front switch
    Big can cap
    XLR’s
