9 Watts - Stereo
Power Amplifier DUAL MONO layout
COMPLETELY NO FEED-BACK (EVEN LOCALLY)
SINGLE ENDED 300B DHT INDUCTIVE
PS AMPLIFIER
The
RD
300-B is a
9
Watts Stereo Power Amplifier DUAL MONO layout completely no
feedback (even locally) made by 2 Single Ended stages using the 300B DHT as
output power tube. The Royal Device design implements a pi-grec inductive power
supply and the filaments of the 300B are supplied with dc voltage at high
filtering (56,000 uF per filament) to suite a very low noise output. The 12 AX7
tube has been chosen for the high linearity for completely no feed back
application.
