Today’s 2 Project’s Finish soldering on all the SMD Melf resistors for my Stereo All in one SSR board and do some testing. & THEN work on my Aleph Mini Class A project using 2 MeanWell SMPS powersupplies ! I have been working on this for a few weeks now and FINALY got the noise removed on the PSU’s so now I have clean ripple free 25V dc rails VERY excited because now I can work on the next stage of this project !!
SMPS units are Meanwell IRM-60-25 units.
Happy dance !

Well, looks like all my hard work that I have put into this project has lead me to ordering Revision 2.0 ! Will be ordering 20 boards to populate a few and test then give a few away for others to use !
Once the new boards arrive & I have a few built, I will do another video and post it on my youtube channel.
YEP ! For Christmas present I bought my lab a new tool ! Almost every year I try to buy a new piece of equipment, slowly building up my equipment pile for the bench. ! Last year was my JBC Soldering Station !
This year we got a new QA401 Audio Analyzer from QuantAsylum ! I have been reading lots about what it can do, not sure how to use this device fully yet BUT that’s the best part, learn and have fun !
Been working on my SSr project over the holidays and when I had downtime at work. I’d have to say 40% just looking at the screen figuring out how to make the board flow nice, look nice, and build nice.
I’m pretty happy with Revision 2.0, it allows to be mounted to a pair of binding posts & also be mounted off board ( oh look I need to add mounting holes ) BUT wait, there is a reason for this, Revision DUAl 1.0 is going to come out soon so, we can wait for that.
Going to order 10 boards soon, then test these, if all goes well, I’ll order more boards and possibly sell kits as blank boards OR fully populated.
Alright I’ll start off with, it has one issue, took me a while to find out what I did wrong ! BUT, it works perfect and I accomplished my goal!
What was wrong ? I somehow missed a wire in the pcb drawing process and didn’t tie input sense to the speaker terminal, very important wire too!
After finding the issue and making the missed connection she came alive and worked perfectly ! Now onto revision 1.5, made a few changes and have a few more ideas for different versions for new applications.
