BS2625 - Bellset No.25 Emulator
Another of our unique products and the answer to the difficulty in sourcing the rare bellset No.25 or 37.
This smart little board is designed to fit inside a Bellset No.26 using the existing fixing holes. It adds a speech coil and gives the functionality of a Bellset No.25 for use with, for example, 150 candlesticks, 162 Bakelite telephones or Hull Monophones.
All existing wiring inside the bellset can be left in place and the wiring for the intermediate and line cords are attached to the new board. It even has the 3.3KΩ bell resistor fitted to the board with space for a bypass link if you are using the later 1000Ω coils.
