While examining one of my A-110-1s to help answer a forum question I noticed that it was equipped with a TL064 op-amp. A quick look at the schematics revealed that it is part of the waveform generation. I am not an expert but from what I´ve learned, the 064 is usually not the first choice for audio applications. So just for fun I replaced it with a TL084 I had lying around.
Do you also have the problem that sometimes the an oscillator of your Behringer Neutron is out of tune when you bypass its tune pot?
I had that a couple of times now and didn´t know what to do about it until today.
I assumed being driven by 3340 ICs the Neutron would not need any warm up time but maybe I am wrong. However during boot the Neutron calibrates the OSCs internally. I found that when you lock a Tune pot and the corresponding oscillator is out of tune thereafter, you should switch power off and back on so to force re-calibration. Mine was perfectly in tune after having done so.
Following a topic on a forum I modded my VP1 for slower sweeps of over one minute. Continue reading
