|Bakelite 232 Telephone (No Bell Set)|
If the speech quality of your 232 telephone is not as good as you think it should be check inside your telephone to make sure you don't have this problem first.
This removal of vital components degrades the speech quality of these telephones by approximately 75%. The telephone will still appear to work however the sound quality, usability, and compatibility with the telephone exchange is significantly reduced.
It has also been pointed out to me by a colleague that this removal will also cause permanent damage (over time) to the original telephone ear receiver, due to constant DC polarization.
