Astral candlestick phone
Apologies if this has been asked before, but i find it hard navigating around a forum.
I have been left by my late mother an Astral candlestick brass phone which works, but has extremely low volume. You can hear the dial tone and ring out. but you can barely hear the other end. Has anybody any ideas how to fix The s Number is S/1214/3/H/500865 Thanks in advance |
Re: Astral candlestick phone
If the receiver is a diaphragm type it have have become stuck.
Can you unscrew the earpiece and post a photo showing what's inside? |

It's more modern than I thought - press-button not dial. Early Astral phones were dial and I assume closer to 700 series circuitry.
I think the receiver is probably a cheap moving-coil speaker and unlikely to be faulty if it hasn't gone completely open-circuit. The base unit is probably all "electronics" |

Could it be on the circuit board then, as I am at a loss and if so can these be replaced? Any surgestions to fix would be great.
Here is a pic of the base wiring. |

The dial tone is very quiet (it does not ring as it does not have a bell ) if you dial a number it will dial and when the other person answers it is very quite as well and you can barely hear them.

Re: Astral candlestick phone
OK.
There's some confusion here. What people of my age refer to as ring tone is what you hear in your ear when the phone is ringing at the other end. Younger people understand ring tone to mean the sound a phone makes when someone calls it. |

Re: Astral candlestick phone
When I joined Post Office Telephones back in 1967 it was called Ring Tone or Ringing Tone. It was still called that when I retired and as far as I know it still is.
Faultsman's Ring Back or FRB is something quite different. |
Re: Astral candlestick phone
"Properly called ringback".
It was always ring tone when I worked for the GPO/BT. |
Re: Astral candlestick phone
I'm glad you agree Euros. I don't like to see history being rewritten.

Re: Astral candlestick phone
In post #9 you twice refer to "ringback" and give it two different meanings. Now you've changed your mind and posted a link to "Ringback Tone", something completely different.
In all the years I worked for POT/BT and two other telcomms providers it's not a term I ever heard used in the UK. This thread is about a vintage telephone so I think that ring tone is most appropriate. We both know what we're refering to though regardless of what we chose to call it. |
Re: Astral candlestick phone
Reseat the plugs on the circuit board. Check the reverse side of the board for cracks in the tracks.
Do any of the electrolytic capacitors have bulging ends or show signs of leaking electrolyte? If so they're ripe for changing. I think I can also see some tantalum capacitors. Have any of them exploded or gone short circuit? If you google the IC types you may find that one of them is an audio chip which may have failed. In the absence of a circuit it's a case of poke and hope though. |

Even BT still refer to it as 'Ringing Tone' on their documentation - see their latest SIN 350 about PSTN Tones and Information Announcements where they are all defined. "Awaiting Answer Indication (Ringing Tone)" It is another case of the internet rewriting history - a term that has more than likely come across the Pond with mobile phones. They don't have NU Tone over there either. They have a tone called 'Reorder Tone' Anyone familiar with setting up VoIP telephones or Analogue Terminal Adapters will have come cross the terms there. We still refer to 'final selectors' but they call them 'connectors' - we have telephone exchanges and they have 'central offices' If it is still 'Ringing Tone' for BT, it's good enough for me. |
Re: Astral candlestick phone
OK gentlemen, I concede it was not in the GPO/BT lexicon!
I first became aware of the term in this context about 25 years ago, but it looks as if it was an American expression (and therefore probably adopted in many other countries). Here is a US patent document from 1974/75 that mentions ringback tone in the context under discussion 58 times, and at least once without the word "tone". http://www.google.co.uk/patents/US3920913 It wasn't my intention to subvert anyone's understanding of telecoms terminology, even less to rewrite history, and I apologise if I gave that impression. |
