• Anotaciones
• In 1922, the Wireless Specialty IP-501-A was introduced. It combined the IP-501 and the Triode Type-B Audio Amplifier into one long cabinet. The consolidation made the IP-501-A easier to build since everything necessary was in one cabinet rather than two separate units as in the IP-501 and Triode Type B amp. The later versions of the IP-501-A eliminated the Telephone Condenser switch circuit and replaced all of the nickel plated binding posts with bakelite capped binding posts. At the time the IP-501-A was introduced, the general public had become interested in the new Radio Broadcasting. The market for entertainment radios sky-rocketed and most manufacturing concentrated on radios for broadcast reception. The commercial users were certainly not as numerous as the general public market and because of this the IP-501 and IP-501-A production level was never really very high.
