What problems did you have with the proposed schematics?
You should look into reducing the gain. You have more voltage gain than the original design, lots more. There were a couple of mods tossed around. You could definitely live without the pot if you do that, and add it in later.
Hi Holland,
Sorry for taking so long to answer you. I've been feeling guilty.
I appreciate your suggestions. So what's my problem? (Don't answer that)
I cobbled together some interim components on a little proto solder PCB from RS.
I also ordered all the necessary good components too.
I've never "worked" with one of those copper clad boards. What a mess. It looked like a 3rd grader did it and this is after multiple uses of my Soldapluz. I'm looking at it thinking, how am I going to implement this mess? Logistically mounting the board and such.
I have DipTrace and I've laid some circuits out. Creating components, pads, and schematics, but when it comes to laying out the PCB.... even using auto function the result are sketchy at best. I would need mounting holes, etc. The only feasible mounting position is on the wood enclosure. I didn't like that.
Next do I try to etch the board myself of pay to have one made at a minimum qty charge. I was thinking, if I etched my own it would look like the RS copper board. I got to the... I want this over and done point. Listen to music. Short story, I whimp'd out.
As such I thought the slam dunk cleanest compact approach is a Goldpoint 23 step attenuator. I'm waiting for a custom L bracket from Misumi Automation. If everything fits, I will order one.
