Yep, smaller seems doable. Lm339 in so14 package and smd relay. Should be able to cnc mill board myself.

I found a backplate for Neutrik NC4FAV at oshpark.com. But I think I also need some protection for the dynamic headphones… …schematically same as Kevin’s protect3. Board size 2.75in x 1.95in. With a little creativity the board can probably be made a bit smaller.

It’s an awfully warm summer here in southern Sweden and it’s too hot to sleep… did this last night… Video_22-08-19_09-57-37.mp4 An attempt to make a smd version of CFA3. Same board size as the smd version of Dynahi I built some months ago. Lots of more work… doubt I’m capable to get this to work though.

and this

Lovely – smds on breadboard. Excited to see lt8365 on a similar board.

Happy Birthday!!!

Thanks for the suggestens. It turned out to be this… Two unsoldered pads inside amplifier to the right. The amplifier has been working all right for a couple of months, until now. Luckily, I noticed the two missing pads. No bad apple, just a poor soldering guy.

By coincident I saw Jazz Piano Player Roberto Fonseca on Mezzo TV Montreal Jazz Festival something, playing solo piano. Thereafter I grabber a bottle of wine and found/enjoyed

Not built today, This combo works realy good but this combo is not good. Where is the bad apple?
