Testing a stereo.

Discussion in 'Mech Tech' started by Lasty, Jun 8, 2020.

  1. I've got a decent period radio/cassette () and want to test it prior to insertion .
    Connecting up to12v will determine the thing does what it's supposed to but I don't have any spare speakers kicking around so the question is , could I test the outputs work by putting a meter across the relevant wires and get a small voltage reading ??
    Would that work ??

    Ta..

    The lights should come on. If it had FM stereo then sticking a bit of wire in the aerial socket and turning the tuning knob smoothly would result in the stereo LED flashing on and off as you tune.

    And if you wind up the volume high and put the meter on AC across the speaker wires, you should see something as you tune across the medium wave band with a wire in the aerial socket if it does not have FM.

    what sort of connectors does it have?
    should be a 5 min job to test?

    I don't have any spare speakers, but the cables to the fronts are accessible(ish).

    You could always bring it over and give it a go?

    Go to a scrap yard and get some speakers . Car speakers have realy improves since the days of my buying the lloydtrons speakers at £3.99 for my Vauxhall Viva . Look for a good quality car, the scrappers almost give them away

  6. I am guessing it doesn't have a headphone socket?
     
  7. You don't need speakers to see if it chews up tapes. If you haven't played the test tape for a while, make sure it rotates freely beforehand - remember the pencil trick.
     
  8. Surely you can find a speaker somewhere... I have some in doorcards in my garage if you wanna test :)

  9. Plug it into your stereo speakers.

    Wrap bits of wire round headphone jack plug any two rings or the tip will do. The headphone will make noises..

  12. The car radio's unlikely to notice.

    I have driven house speakers from a car stereo before. Wasn’t sure if it was the done thing for testing.
     
  14. It's fine.

  15. I have spare speakers that you are welcome to, I can drop them off when I'm out for a cycle if you would like

  17. Thanks for the offer Colin , i was just looking for something tedious to do at home today !
    I`ve given it a `once around the block` at home and everything seems to do what it`s supposed to so i might as well just go ahead and fit it instead of messing around with it but thanks again :thumbsup:

    Thanks as well Andy , much appreciated but as above , i`ll pop the stereo in and see what happens :thumbsup:

    Thanks for all the other replies , just to close this i remembered you can run mains speakers from a car stereo !!
    I recall them being in the back of a Morris traveller owned by a certain young lady , was a bit of a squeeze but we both managed to get a little sleep ... ;)

    :hattip:
