This AUDION was a jewel legacy of my best friend in Bandung city.
Extensive customizations were done , amongst them :
# Speaker binding posts replaced with Cardas bindings
# All original coupling caps were replaced with MBM PIO 0.25uF/500V
# All signal resistors changed to Riken Gold
# The electrolytic power-supply caps were replaced with RIFA 250uF/400V
# Powersupply Sprague 20uF/500V installed, and a mix of Blackgates series for
the anode and cathode caps
# PIO Bypass caps 0.1uF/0.25uF and 4uF were installed at power-supply caps
