@JoaMat Here are some boards I drew up...

Got the micro up and running. This is set for 12v. Depending on the op amp this should support from 5v to about 20v. The larger should support from 12v to 50v. Noise looks good but I really need a screened room.

Nice Joachim I've been playing with this servo in LTSpice as well. Here's what I came up with... I added a 1K resistor across Q5. I didn't have R17, but I like it and it seems to model better. D2 is probably not needed but wanted to protect Q5, just in case. Have you tried it without the 2.2pF cap across the 2 Meg resistors. I'd prefer not to use this. I'm enjoying the show

Mini and micro versions of the gr78xx supplies...

Happy Birthday Doug! Enjoy

Happy Birthday Al! Enjoy :D

Thanks. Steve reached out to me as well

I wanted some of the THAT340LSK adapter boards. Not sure how to order since the spreadsheet just lists THAT340 adapter pcbs. Thanks

Happy Birthday!

Happy Birthday Nate! Hope you enjoyed the day

Happy Birthday Craig!

I just finished building the uTracer 3+. Works nice. Needless to say I spent the day yesterday measuring tubes.

Happy Birthday!

I actually liked the how the Viva sounded (although it was very loud in the main hall and I had to turn the volume all the up to get it to an appropriate listening level). Would need to listen to this in a quite environment to really know how it sounded.

Happy Birthday!

Very sad Todd. My deepest condolences to you and your family.

Happy Birthday Colin! Enjoy the day
