Re: Designing the pcb
As this version I'm doing for the preamp is TH, which cap type should I use for the input filter of the XLR. Values are 470p and 47p. Film types are fine, but ceramics are smaller for that. Although no all ceramics sound good for audio. On a different project I would go for polystyrenes, but they ar...

Re: Designing the pcb
Very and sadly true. Now I'm fighting to not reduce the main board too much, but it has to leave place to the front board. As it has to be a bit high too (14mm) so I can place two switches below, for phantom power, I better consider that on the front board's back too to make up space. Sorry, I'm tal...

Re: Designing the pcb
Olaf,
Unfortunately I might not be able to do that on any part I'm interfacing between boards.

Re: Designing the pcb
I'm not too clear about the "differential receiver on the other end" concept, practically speaking. You mean adding another active stage at the other end? About sending both signal and ground together, always, back and forth, I agree with you mean. I suppose you mean the signal gos to the ...

Designing the pcb
OK, schematic is finished and now it's time to design the pcb. For that I will be using DipTrace. As I'm building a portable design, that will enclosed in a small box, I will have to use two boards to hold the schematic, which is quite large. It has an input stage (discussed on another thread and ba...

Re: Simple pcb design program
There would be taxes and else to use Express PCB from here. Not a good option.
What I'm seeing is that DipTrace is very much like Altium which I will have to learn sometime, but simpler. So when the time comes it may help.

Re: Simple pcb design program
Yes, of course it outputs Gerber files. It shouldn't be a commercially viable program if it didn't.
Listen to this, under Manufacturing.

Attached is also the screen with the Gerber option.

Re: Simple pcb design program
Unfortunately manufacturing is an issue in this case, and even if my partner knows and prefers Altium, he's handling an smaller SMD version of this project. I'm in charge of the through-hole version, as we are on different countries and I have a lot of TH parts I can use for the 4 or 5 prototypes I ...

Simple pcb design program
I am having some trouble finding what I call a "bread & butter" pcb design program. I have tried several, but the learning curve is quite steep, and I I'm looking for something simple. Didn't get along with Eagle or KiCad, their tutorials are very poor. So I'm looking for something sim...

Re: Phono Preamps
Code: Select all
PS: Note the P-10 only used electrolytic caps inside global feedback loops so they were sonically well behaved. Audible frequency poles used film caps.
