Hi all,
New member, thanks for the add!
I don’t know much about electronics, but here to learn
I recently got from the local car boot, two WW2 British ‘L’ field Telephones. One in somewhat rough condition dated 1941, the better one 1944. I’ve thoroughly cleaned the contacts, re-soldered some of the perished wires and added D size battery holders, and they work great.
My question for the experts - although I can have a conversation between the two phones, talking into the microphone in the handset of the ‘1944’ phone, is very quiet when listening on the other phone. I swapped over handsets between the telephone units (‘1944’ handset in the ‘1941’ unit, and vice versa), to make sure there isn’t a potential problem in the ‘1944’ telephone unit. It’s still the same problem on the same handset.
Would anyone know what would cause the microphone to be quiet? I’ve tried to take the Bakelite mouthpiece off the handset to have a look at the microphone, but I can’t for the life of me see how is comes off!
Many thanks for your patience for a newbie.
Best regards,
Simon
