Congratulations on the purchase of the Seagull Bluetooth Speaker PCB. This is the only
Bluetooth retrofit designed specifically for retrofitting antique radios. Your retrofit radio will
provide outstanding audio while maintaining the look, feel, and user experience of the
original. These notes provide guidance so you can take maximum advantage of the Seagull
PCB's features, and create a retrofit that will be enjoyed for many years. You'll also get tips
for minimizing the radio modifications so it could easily be reverted to its original condition.
You can download these instructions at https://seagullelectronickits.com/. You'll also find
valuable information in the instructions for the Potentiometer and Wiring Kit.
These notes are divided into five sections:
Features and Configuration – This section describes available features, connections
between the Seagull PCB and radio, and how to configure the PCB via configuration shunts
and jumpers. Two wiring diagrams are shown: Figure 1 shows the wiring for all Seagull PCB
features. The diagram in Figure 2 shows the wiring for minimal features. There is a simpler
wiring diagram in the instructions for the Potentiometer and Wiring Kit. Your retrofit will use
some or all of the features shown in these diagrams.
Reference Material – This section describes all the connections and programming
shunts/jumpers on the PCB.
Retrofit Tips – This section provides tips for minimizing the impact to the radio so that it can
be returned to its original condition.
Specifications – This section shows performance specifications and mechanical
dimensions.
Resources – This section shows sources that provide parts to help with your retrofit.
