Eurorack DIY: Output module

This video covers the design of an Output module for my Eurorack, featuring a powerful headphones amplifier, a LED bargraph VU meter and Balanced line outputs.
The PCBs are available at PCBway for purchase:

Now this is excellent ratio between theory and practical applications. Plus the legendary book! Top work! 💪💪💪

Thank you my friend!

[@matrix12x]

Awesome module!! Are you putting this one on your tindie page?

[@MeeBilt]

Thanks, @matrix12x! I plan to do this in the near future, but I think that I will replace the 3.5mm HP jack with a 6.3mm type first.

@@MeeBilt looking forward to it

hello ! we are actually creating your output module with a friend but we don't have the HP jack output 3.5 for now, we have tried the module without it and we don't have any output signal , my question is: does the HP output complete the signal way to the main out? if yes that the reason why we don't have any signal... also why in the first video the HP output have 3 pin 3.5 but in the second there are 5 pin 6.35 ? happy for an answer and have a great day!

[@MeeBilt]

Hello! The headphone output and the balanced outputs are two separate signal paths, each with their own volume/gain control. Do the VU meter LEDs light up when you apply an input signal and turn up the gain pot? There are two versions of the Output module, the version on Github are the first one with 3.5mm jacks and the second one is available in my Tindie shop only.

[@leosoler580]

@@MeeBilt no, the LEDs don't light up, and the HP output is the only component we miss

[@MeeBilt]

@@leosoler580 Then you have to follow the signal path from the start and see where the signal disappears

@@MeeBilt thanks for your advice i'll try that ! Have a nice day

[@unsoundmethodology]

This is very nice! I built myself a quick and dirty headphone amp on stripboard a while back on a similar model (just two input jacks, the left normalled to the right, then the dual pot into parallel NE5532s; I mostly copied from that portion of Befaco's Out module), but this seems so much more comprehensive and useful that I may have to build yours. Thanks for detailing this!

Thank you very much :)

So happy to partner with you 🥳🥳🥳

Thank you very much - I'm looking forward to the next project! 😀

Hello! I want to build Output Eurorack module from your GitHub and I have one question: in schematic you use C33 and C34 like as 47uF SMD caps, but I’ll make this module in TH design and can't find ceramic 47uF TH caps in my local store. With what nominal or type capacitors can I replace these SMD's?

[@MeeBilt]

You can use bipolar electrolythic capacitors, for example nichicon VP-series

@@MeeBilt thank you for answer!

Beautiful

[@MeeBilt]

Thanks!

[@rautshsale1948]

pretty much binge watched your entire channel in a day (home office privilege lol) holly shit, channels like these is what i've been looking for. have still a long way to go, as i'm currently learning the very basics of electronics, but am so looking forward to make my own modules in the future. this channel is very inspiring. am very much looking forward for what's next

[@MeeBilt]

Thank you very much for those nice words. I'm delighted that you like the videos and find them inspiring. Cheers!

[@mymodularjourney]

Great explanation again. Always eagerly awaiting your new videos.

[@MeeBilt]

Thanks a lot - I'm delighted that you like the videos :)
