Do you like the analog VU meters, as we do? We decided to extend our 500 series with the preamp, based on our 501preamp. Just added the more informative VU and a bit changed switchers functions. Now you have a Polarity/PAD switcher. A usually, clear sound filled with harmonics and soul. The amplifier has an instrument input (HI Z) and a built-in phantom power supply. A usually, clear sound filled with harmonics and soul. Every device is proudly handcrafted for you.

This device is the first and in our line of 500 series devices. Basic in function, anything but basic in sound! This preamp is able to outperform many similar devices on the market. In addition to delivering crystal clear sound and high gain, the PA501 can bring music to life. This is a complete tube preamplifier with input and output transformers. The ability to select the type of input signal allows you to work not only with microphones of different sensitivity, but also connect a line signal to the input. The 500 series standard imposes restrictions on the modules, it concerns the supply voltage, the size of the device and the front panel, etc. In contrast to the solution of many competitors for powering tubes with low anode voltage, we provided the stages with optimal power. This made it possible to unleash the potential of the device and obtain a dense clear sound.
