EQ573 Equaliser / Frecuency response EQ573-II when active

« on: May 08, 2023, 10:17:25 AM »

Hi!!!

Im just build two EQ573-II and they work and sound amazing!!!

The only thing I don't know if it is normal, is small changes in the frequency response when the EQ is ON, but not EQ is applying.
Also, when I select some LF frequency, the signal level falls off.

You can see this in the attached images

Thanks!!!

CP5176 FET compressor / Need help with 2:1 to 20:1 ratios

« on: April 10, 2022, 01:31:07 PM »

Hi!!

I have a CP5176 compressor, but the ratios 2:1 to 20:1 not work. The signal seems pass without compression. 
The AC levels on TP3 are 0V except for SLAM ratio that is 6.6V.
All the other levels are OK.

When I meausured the V+/V- voltage, maybe did some cortocircuit with the tester pin and some smoke came out of one of C31/C32 capacitors. Could this be the cause of this problem?

Thanks in advance!!!
