LaChapell Audio Vacuum Tube PreAmp with Jensen Mic Xfrmr

The LaChapell Audio Model 583s was the world's first vacuum tube mic preamp designed for the 500 series format. It is still the only 500 series module to properly power the tube with 250V of TrueTube technology. Unlike some other vacuum tube mic preamps for the 500 series, LaChapell does not starve the tube of voltages in any way. And, since this all occurs within the 583 module, there is no worry of harming your 500 series power supply. With dual drive knobs to separately drive the input and output, the 583S provides total flexibility to explore a broad sonic pallet enhancing its versatility for all of your recordings.
