Re: Balancing Resistors Reduce Voltage Follower Common Mode Distortion

I'd reccomend an OPA1642 over a 2134 if you could still buy them right now, but it seems they'll be out of stock for quite a long time. LM4562 can work well, if you keep the input impedances low enough - usually gives an audible improvement over the 5532 in all circuits, with proper PS decoupling. ...

Re: Balancing Resistors Reduce Voltage Follower Common Mode Distortion

Thanks for posting hellalive. I also found that to be true. I haven't posted my OPA2134 measurements where the effect is quite large. I'll be using a 5532 primarily in the Wet Dry Mix Add's voltage follower which is why I focused on that first. The OPA2134 will be recommended in that circuit when a ...

PC Power Supply Failures After Running on a UPS

Had an interesting set of coincidences happen today. I run 4 PCs in the Office and Shop. Three are on one UPS and the workbench PC has its own UPS. Both UPS are older APCs and the ATX power supplies in these machines are around 10 years old. One may be older. Around 2:45 AM we had a large area powe...

Re: The Corona Virus Hoax of 2020 = 2022 "Vaccine" Injury And Depopulation

George what I'm wondering is if the people who were duped the first time are going to continue to be duped by Monkey Pox this time.

The manipulation is becoming really obvious to the normies but the mass-formed psychotics, of which there are many, are heavily invested in continuous fear porn.
