Quick Project Specs
- Universal design, output voltage easily adjustable with one resistor
- Low output impedance and low hum and noise over the complete audio band
- Output voltage adjustable between 0 and 500 V, up to 1 A output current
- Usable for valve preamplifiers and (single ended) power amps
- Build-in delay function (30 s) for output voltage after power-on
- Three plug-in options available for the pass device: with 6528 valve (max. 600 mA); with EL84/6BQ5 or EL86/6CW5 valve (max. 50 mA), or with DN2540 MOSFET (max. 1 A)
