This model was made specifically for the unbalanced output of a Wurlitzer console, although it could be adapted to many other manufacturer’s organs with a “Console Connector Kit”.
It is interesting to note that unlike later cabinets, this cabinet featured an ELECTRO-dynamic speaker. What this meant is that the 15″ woofer did not have a permanent magnet, like speakers have today, but rather a large coil of wire which acted as an electromagnet. This coil was also wired in such away that is acted as a filter choke for the amplifier’s power supply
