G-Pultec BOM?

[grantlack]

sorry gents, forgot all about this.  i'll get one up w/ lead spacing in the next few hours.  if there have been component edits since the board printing they won't be reflected, as i'm working straight from that.  honestly though the component count is pretty paltry, if you've already got the board it's a quick read.

mmmmmmm pultec.

For the high section it is very tasty to use Styroflex caps.
Can´t be wrong searching for those values.

This is a very great sounding EQ circuit. One of my favorite an most used eqs in my project studio!
A big Thanks to Jacob from Gyraf Audio who made it possible and Gustav who is still producing the pcbs.

Thanks so much man!

What would be a good substitute for these ???
"2  TK4425-ND  INDUCTOR FIXED 100MH TYPE 10RB
1  TK4421-ND  INDUCTOR FIXED 47MH TYPE 10RB
1  TK4416-ND  INDUCTOR FIXED 22MH TYPE 10RB"

Digikey says they are obsolete and their recomended substitute is a minimum 1000 qty.

This is partially sarcasm... ;D, but also an important lesson that will help you greatly.

Watch it in full screen so you can see what I am clicking.

Does this resistor really need to be a 1W one?

 

[JayDubrek]

Niely- pretty certain RS still carry those inductors... Or see if anyone has the IOAudio custom inductor they're prepared to let go of...

I created a BOM a few weeks ago with up-to-date toko and tube sources. I will try to complete it with all links and keep it up to date as i can.
This BOM is for Gyraf Audio G-Pultec filter board and power supply.
