Finally. After assembling and testing rev2.1 boards in August (they had been purchased by a friend some time earlier) last year, and playing since in a "temporary" lashup, the pair of Modulus-86s have a proper home of metal.
After quite a bit of searching online I realised I had a donor chassis hiding in the shed.
It started out life as a pro-sound power amp
Finally someone who understands that the LM3886 needs heatsinking!! 🙂 I love the repurposing. It looks like it turned out very well in this case. Also handy that the rear panel came with cutouts for the XLR connectors.
Very fine work Tom, thank you again for all your hard work, they just play, blamelessly, on 96dB/1watt horns, that is special around here.
Awesome. I'm glad you like it.

Tom, I’ve been planning on building quad Mod-86s for a pair of Lxminis. I was wondering first and foremost if you had any comments on this pairing, and secondly when you think that the boards will be back in stock on your site. Thanks!
Which boards is it that you need that aren't in stock? I have plenty of stock of all boards. I just updated the Power-86 to Rev. 1.2. I should have the documentation updated within a week or so.
LXmini + 4xMOD86 powered by an Antek AS-3222 and Power-86 was my daily driver until the Modulus-686 came along. I liked it.

Now that I've managed to complete the requirements for my psychology degree (formal graduation is in June), I'm looking to push full-time on Neurochrome. I have a few new products in mind and would greatly appreciate your feedback on my ideas. If you have 15 minutes to spare, I would really appreciate your participation in my survey (linked to below).
Neurochrome Spring 2019 Survey (link).

Thanks in advance.

Congrats on completing the degree. I assume you are not intending to practice psychology?
I started filling in the questionaire but then realised that I'm actually not in the market for anything until I've cleared my backlog which is currently on a 1:1 slip trajectory so my answers would be somewhat coloured by that.
Gimmie another couple of years and I'll be caught up and have a bit more disposable income as well ( 2 leaving uni this year, 3rd in 2 more years!). 🙂

Nah... I'm not qualified for that. I just completed my bachelor's degree (with honours and a good GPA). If I want to practice, I need a minimum of a Master's degree. That's another 2-3 years.
My BA degree work has provided me with a lot of insight that has been helpful in my day-to-day interactions with customers and clients. And my business has grown while I've been in school. I think I have potential. Hopefully, I can convince others of this too... 😉 I'll push on the business for a few years to see where I can take it. I love the engineering and enjoy the human aspects of running a small business as well.

Hi Tom,
Congratulations in completing your degree! Wish you all the best with your current and future endeavors.

Thank you. It was quite a relief when I finally submitted my honours thesis (research project).

hey Tom congrats for your degree! Also, completed the survey, IMO the "NO Volume control" question / answers combination is a bit misleading, maybe it's because I'm no native speaker, but I thought you'd like to know.
Thanks. I appreciate it. I struggled with the wording of the "NO volume control" question, so that might be what you're picking up on. Some would like their headphone amp to not have a volume control as they take care of that in the digital domain. That's what I was getting at.
Thank you for your participation.
Tom

I just completed the survey, hope it helps 🙂
craigtone,
Nice work there with stuffing the PCBs.
Choose you chassis quickly, and get the amp playing music. 🙂

How much power a stereo modulus will deliver with that power supply? 30W/channel?
According to the Neurochrome website: 28 W into 8 Ω
It's good to see a build shaping up. Nice work so far.
Yep. 28 W into 8 Ω with the SMPS-86. 28 W into 4 Ω too (the IRM-60 reach their current limit). For a desktop amp or an amp intended for powering efficient speakers, the SMPS-86 is plenty - especially with 8 Ω loads. If you have 4 Ω speakers and tend to really crank on the volume knob, you should consider using two SMPS-86 so you have enough output current available.
