Filters should be designed with same gain.

Same filter was flashed between 1.15/1.20+.firmware but the volume still is less on the red filter slot.on 1.15.i would expect them to have the same.volume as the gain is the same, unless you
changed the internal values in the firmware for digital volume in later versions?

Update: Reflashing firmware fixed it.

The "1021filt_105.txt"... what was this? Short, shallow? And came after 099 which was technically much better? Why? Just want to know the story

Sören, please explain how "shared filter" work. When I generate a filter in rePhase I'm asked for a rate. How does one and the same filter work for different rates?

@TNT: Johan could you please upload the latest filter pack including your great filter in F4, but with the DC Blocking ACTIVATED? If I had the txt file I could change it myself and compile a skr file, but I understand you're not willing to publicize the txt file atm.

I'm asking this favour because lately my amp has been blowing fuses and popping tubes and I'd like to be on the safe side.

It would be interesting to know if your fuse problems goes away. Also to know which files causes it.

Wow, wicked fast response TNT!
I'll give it a go and see what happens. Of course I'm not sure the omitted DC blocking is causing the fuses to blow.

Thanks a lot.
