Transformers & Chokes

Transformer - Radiola III-A Replacement Audio, Hammond
Developed in response to requests from RCA Radiola III-A collectors. The original transformers are usually found with open" windings due to the fine wire and high turns usedcoupled with age. This is a universal replacement type - it will replace any of the three audio transformers used (1st audio driver2nd audio-phase splitter stage or output transformer)by correctly connectiong the 5 lugs. A pin out and connection diagram is included. The cases from the old transformer will fit this new unit. The terminal board is a duplicate of the original. Key Features
