      @@JustinHeronMusic Hmm interesting. How is your experience with it, how's the sound? When I have compared a real L2A2 with Slate's plug-in version, I've found that the hardware distorts the consonants of vocals nicely, and just had velvety saturation overall compared to the plugin, which sounds more clean and mid focused. I feel like I have to add some tape saturation afterwards to get a bit closer to the hardware.

      @@djentlover The "effortlessness" of the hardware is what makes it worth it to me. The plugin has a "squeeze" to the compression. Thicker, more dimension, and more sheen is how I'd describe the hardware.

    Nice video, neatly sums up most if not all details worth noting when building this.
    I've had my pcb/trafo in storage for years, gotta build it up at some point. Got most of the cheap parts, but trafo's and optical cells are a substantial expense :S Have a D-AOC that's just missing a front panel that has been prioritized, but rack units are staring to gett sparse in the studio...
    Keep up the good work and all the best from a fellow Gdiy'er :=)

    • @shoetiquemusic
      @shoetiquemusic  11 месяцев назад +1

      Hi Magnus! That Dual AOC looks pretty neat! My understanding is this project started as an LA2A build by analag that evolved into a unique optical compressor. Did you get your PCB from silent arts? It looks like they might have stopped producing/selling that one.
      Do you plan on making your own front panel or having one screen printed?

    Great video. Not my particular preference to doing a DIY though. I'm much more into the idea of an actual, complete kit, rather than a circuit board and BOM; where you need to go on a scavenger hunt and chase down all the other components yourself - pretty much every build I've tried that way turned out to be an old maid - so I just won't do them anymore. Aside from CAPI, AML and Hairball there just aren't that many people offering kits like that anymore. Seems to me that Group DIY was a much more interesting place about 10 to 15 years ago; things there really atrophied about 10 years ago in the mid-teens. I really miss the Analog Allstars 500 series Pultec clone: one of my favorite all time builds ever; it's a wonderful walk through Wima's product line! Unfortunately there just isn't much of interest on the White Market page anymore (it used to be multiple pages). Most of the people there selling kits over the years either went on to sell assembled gear only like Serpent Audio, or quit the business altogether. It's a real shame - I think most of the best analog gear I own was built from kits, not purchased retail.

    • @shoetiquemusic
      @shoetiquemusic  4 месяца назад

      Hey Jimmy! Thanks for checking out the video. I agree that the options for fully assembled kits can be limiting - especially for full size rack gear. In addition to what you mentioned above, kits are also offered by Sound Skulptor, DIY Recording Equipment and Yann Lu Audio. You should check those out! Don Classics offers kits that are 'near complete' - they provide a link to a Mouser cart which contains the necessary parts.
      I think kit making is super time consuming and I imagine that the profit margin is razor thin. Having put together several non kit builds I can see how much of a pain it is to gather all the parts in one place!

    Great video; I would love to put together something like this, but I have no idea how! Do you have any recommendations for some starter projects for someone with absolutely no experience with making audio gear?

    • @shoetiquemusic
      @shoetiquemusic  6 месяцев назад

      Hell ya Zach! If you're looking for a place to hone your soldering skills I would start with a guitar pedal. Aion Fx has some nice kits that are well documented and won't break the bank.
      Once you can get through a couple pedals you could try something more advanced like a 500 series unit from Sound Skulptor. Alternatively you could try a nice FET compressor from Hairball Audio. These projects provide nice build guides and take away a lot of the guess work.
      Then, when you're feeling bold you could try tackling something like the DLA-2A!
      Let me know if you need help deciding on a starter soldering iron or any other basic info. I'm always happy to help get someone into the hobby!

    • @shoetiquemusic
      @shoetiquemusic  9 месяцев назад +1

      I appreciate that TG! The only place I know of making Pultec kits is Audio Maintenance Limited: www.audiomaintenance.com/acatalog/aml-17-022_extended_info.html . They have an EQP-1 and MEQ-5 Kit.
      The EQ-1 in my videos was built using a Drip Electronics board. You have to source all of the parts yourself. Greg at Drip sometimes has prebuilt shopping carts for Mouser or Digikey that can make the process easier. I'm not sure if you can still get these - you could try emailing them. www.dripelectronics.com/feature
      The MEQ-5 at the bottom of my rack is a point to point built using a wiring diagram and chassis from analogvibes. If you go this route don't get caught up in being a purist. Substituting some of the parts for modern production items will make this a lot more enjoyable and have minimal impact on the performance of the unit. These are still available for sale. They also have an EQ-1 chassis. analogvibes.com/

      I've noticed over the past 20 years those resources have drifted from building stuff to buying new gear from the big name companies unfortunately. In all fairness, my main rig is an ICOM 7200 I use almost entirely for digital hf so I can't rant too much about that haha
      I also lucked out as a teen to be in a club with some OG Motorola engineers who took me under their wings to teach me about homebrewing stuff. A few were guitars as well and built my first tweed champ clone with one.

    Nice build dude! I'm building one of these atm. I'm just waiting on my custom case to come through so I can finish off wiring it up. Pretty much everything else is in place!
    I have a couple of question (as I can't get onto the GDIY forums, as my account keeps getting banned every time I sign up as they require you to pay to join, or they IP ban you within 24 hours for good!).
    Firstly What is that funky high tech looking ground connector you have connecting the PCB channel ground to chassis ground star wire? I want that, it looks super bomber! xD
    Secondly, with the pots, or in your case the stepped switches, are you using 3 core sheilded wire, and if so, are you tieing the sheild into the the grounded pin of the pot at the board side? If not, how do you have it set up? I would experiment with the grounding, but I'm running low on moplex pins, and will only have 8 left if I change out the pot wires, and I still may want make other alterations down the line.
    Thanks dude.

    • @shoetiquemusic
      @shoetiquemusic  6 месяцев назад +1

      Hey Dafty Boy! Regarding the PCB ground: Are you talking about this item? www.digikey.com/en/products/detail/keystone-electronics/4907/255324
      It's called a quick disconnect. I used three of these total. There is another next to each relay. It legit took me a half hour to figure out what I had put there - too many receipts for this project!
      For the the gain and peak reduction wiring I actually used some left over microphone cable (2 core shielded). Not sure if this is the best approach but the noise floor on my unit is very low. The shield is connected to the slot for ground in the pcb side molex connector. The bottom of this document shows how to wire the pots:
