I have been meaning to make one of these into a bench supply and today was the day. BOM attached for reference. I kept the common for each section next to each other so if I need to tie them I can use a dual bananna jumper plug.

Re: TDK-Lambda Single, Bipolar and Triple Output Switching Power Supplies for Audio Projects
And now Digikey has zero. Literally 189 two days ago. Glad I ordered one.

Re: Texar Prism clone prototype Finished Version
Yeah the PICs are still at zero inventory but I did buy enough of them to build what I have left and some other parts that I knew would be difficult. I re-ran the BOM manager again and it looks like parts that weren't in stock a month or so ago are now available with only a hand full that I can prob...

Re: Texar Prism clone prototype Finished Version
Hello everyone! I'm still here lurking about the forum. I decided to pull down my website since the interest died off and it no longer made sense to pay the monthly fee but Im keeping the domain name to maybe use later if I have any other ideas to offer. I still have plenty of boards left but the pa...

Re: Discrete Op Amp design
What you describe is phase reversal which occurs when the common mode voltage is exceeded. There are many newer enhanced versions of older opamps that the datasheet indicates as not having phase reversal. The TL072 datasheet is one example. You will definitely see this on a general purpose part such...

Re: Wet/dry circuit
I'm coming in on the tail end of this but I'm harkening back to my compressor project where I took the ADC input of my PIC chip and used a lookup table to generate a log function for the PWM. This would get complicated though unless you added a DAC to the PIC plus programming it. I know I've used th...

Re: Texar Prism clone prototype Finished Version
Whew! Im glad I ordered when I did. On Monday there were 1400 in stock. I ordered 20 to have plenty and now look at it. I have watched this go from 9000 to 7000 to 3000 from the first time I offered my project. I think since the SMD version has been unobtainable since beginning of the year this has ...

Re: Texar Prism clone prototype Finished Version
I had trouble sourcing the SMD caps I use on the display boards. There was only one recommended replacement to choose from. I'm not sure about any thru hole parts. That's another reason I stopped short of supplying assembled boards until this clears up a bit. The other part I see dwindling fast are ...
