The KIT is coming…but before I need a little help from you!

Hey there,

Finally, I’m very close to finishing my long-awaited Tube Program Equalizer COMPLETE KIT – a faithful detailed re-creation of the famous Pultec EQP-1A. 

As you might know, I’ve been working on this project for the better part of a year now, but I’m finally going to wrap it up. The prototype I have built to test the critical components is already working great at my studio 😉

And as the last minor issues in regards to production and distribution are about to be solved, the time has come to go for it very soon.  

The plan is to release the kit still this year BEFORE CHRISTMAS!

But you know, it’s not only about putting together and releasing the kit, but also, if not most of all, about enabling you to build this legendary piece of gear yourself.  

That’s why the release of the kit will come alongside its own, what I call »Build Your Legend Series«, which means I also spent A LOT of time creating detailed, easy to understand and well visualized e-papers and videos for you (like for the LA-2A). 

So, before finalizing everything, I would like to make sure I have it all covered and dealt with all the possible reasons and obstacles why you might have concerns getting your hands on analog gear DIY-Style.  

 

All I need now is you to answers to these questions in the comments below:

  • What are your top two or three questions about building the upcoming tube program EQ  that you’d want me to answer in the BYL-Series?  
  • What are the major obstacles or doubts that are holding you back from starting to build your own gear?

Or –  if you already started to build your own gear:

  • What were the major obstacles holding you back in the beginning and how did you overcome them? 

 

Your questions will be very very helpful to ensure that I’ll cover everything there’s to know.

If you have friends that could contribute, please share this email.

Thanks for everything – I really appreciate it! 

Martin

  1. I finally came up with a couple questions, though you may find the first a bit sacrilegious. I have intention of using all my analog in a hybrid workflow. For recall purposes, it seems like having stepped controls is ideal. For stereo purposes, it seems like rotary switch attenuators are ideal. But the cost for an Elma A47 or similar Goldpoint, populated or bare, seems very high. Especially when considering something like the Pultec EQP1, which would require 4-5 fine-step controls to be truly useful.
    So my question is, is there an affordable way to implement stepped controls, such as a custom circuit board complement to inexpensive, readily-available switches? And would this be more time consuming in the end than using recall sheets and listening carefully dial-in the matching settings?
    The only other question on my mind is how to calculate appropriate resistor values to safely discharge higher value capacitors before working on gear that has been powered. And relatedly what sort of resistor selection to keep on hand for this, and also in general? (Coming mainly from working on kits, I don’t have a large selection of surplus components.)
    Thanks, Martin!

  2. 1) how much
    2) a way to verify it is working correctly

  3. Hi Martin – I’ve been DIY’ing for many years (I’m 55 years oldJ and started with simple kits with clear, step by step instructions. The building is usually the easy part, but the troubleshooting can be hard, especially if you don’t know much about electronics. Some clear guidance to the most common problems is very valuable. I also find strong support in forums from other builders. I’m now in the middle of sourcing the parts for a Poorman Fairchild 670 project which is my most challenging build so far. Good luck with your PEQ1A. I’m looking forward to building a pair of these in the near future.

  4. I think it’s Always good to have a few test points on the circuit. That way you can test parts of the circuit before blowing a few components. Normally everything works fine but a double check is great.
    Also you can help people if they have wrong voltages. What if a tube goes broken, where to find a replacement and stuff like that are very welccome. Thanks! Looking forward
