MP566 Tube microphone preamplifier / Low voltage check failed

« on: January 15, 2022, 11:07:44 PM »

Hello everyone,

When going through the MP566 test guide, I’m stuck at point 4 (Low voltage check). According to the documents I’m supposed to get a voltage between -3.8V and -5V between the TP8 and 0V test pins, but what I really get is -15V. What could I have done wrong?

Thanks,
Claudio

MP566 Tube microphone preamplifier / Olive face plate for MP566

« on: January 18, 2021, 01:59:47 PM »

Hello,

What happened to the MP566 face plate? Why was the colour changed from olive to blueish? I pretty much prefer the olive one, and I heard the same from other users as well. Will the olive panels be available again in the future?

Thanks,
Claudio

CP4500 Stereo Bus Compressor / dbx2150 instead of THAT2180

Hello Jean-Pierre and all,

Can we replace the THAT2180’s in the CP4500 with original dbx2150 VCAs? Can they simply be swapped? Or do we need any modifications in the circuit first?

Thanks,
Claudio
