DIY partial kit PCB for tube equalizer

This listing is for set of:

• 1 EQ PCBs (30 Euro)
• 1 6Н9С (6SL7 direct replacement) tube made in USSR, tested in my own EQ (15 Euro)
• 1 octal socket for tube

EQ has enough gain to not follow it buy the make-up stage, plenty of gain.

PCB is able to accommodate different lead spacing capacitors (in case you want to opt for something different - cheaper or just an alternative). You will receive BOM file as well.

I have few sets like this, so you can order multiple to build stereo unit, if you want.

This listing is only a partial kit and the ready EQ on pictures is just for the example of ready build, I am using this build to check tubes now. I call my EQ "Uniia".

This is the implementation of the EQ from Audio magazine circa 1955, the EQ sounds fantastic.

Check the demo on youtube @HappinessMastering.

Disclaimer: the listing is for PCB only and it is up to you how you are going to build it and use it. Remember, that the anode voltage is high in this build so you need to be careful. This is not the very beginner build.
