Instead of using the wooden board provided by AES, for mounting the components of
their Wireless Phono Oscillator kit, I decided to build the kit on a metal chassis,
for improved safety and convenience. I also incorporated a number of improvements
to the basic AES kit, as shown in the photos below.
Among the added features are:
12J5GT audio amplifier stage to boost low output sources.
Modulation level control on the front panel.
Stereo input jacks to mix both L & R outputs from stereo cassette players.
Fuse on rear panel.
On-Off switch on rear panel.
Antenna and ground binding posts on rear panel.
Silver Mica capacitors in RF Oscillator circuit for improved frequency stability.
Improved power supply filtering
