    oven control board - melted wire connection

    13 years....think youself lucky. No more current than usual, just the time it was on. Trying to heat treat bearings are we...??.....:rolleyes: Burning out is a common failure in spade terminals like this as Alec says. Don't connect back via any board connector. Turn the board over and solder...

    Help with identification!

    It is possible to connect a flashing led to a standard led to get the latter to flash as well.

    Snap Action Switch to Activate Linear Actuator

    Will be rather dangerous if the door is not fitted with "load" or "limit" switches. Does the door need to open from the outside..?

    PANASONIC THEATRE SYSTEM SA-BT737

    Panasonic systems can be difficult...../complex......./costly to repair. Brother had one and after many hours of trolling through schematics and testing, decided purchase of a second hand unit was a better option. ($100) ....even our local TV stereo tech had the exact same opinion. Having said...

    Power connector - looks like a B on its side

    They're on Ebay for example but with the double "nicks". Figure 8 panel socket....you'll need the lead to match as well. https://www.ebay.com.au/itm/324708170763?hash=item4b9a1d7c0b:g:ZeMAAOSwxipg6AA~&frcectupt=true

    Resistor identification

    It's not going to make any difference, as long as it fits.

    Can I use a simple zener circuit to step down voltage for a turntable motor?

    Whatever floats your boat I'd imagine. I know which way I'd be heading, and it's not roll 'yer own. :)

    Strange reply.... o_O

    Is this repairable?

    I'd say the ic's (if you can identify them) are the least of your problems. The board is damaged and repair may be well nigh impossible. Also other components damaged as well.

    Can I use a simple zener circuit to step down voltage for a turntable motor?

    No. As an added note, these motors usually have some kind of on-board speed regulator. Hence supplu voltage 8.4 to 16 v dc. If you need to reduce voltage go for a step down converter. Couple of dollars each off Ebay or whatever and can usually handle an amp or two.

    Is this repairable?

    Multiple failure and flashover points. Looks kaput.....

    my french 1 h/p single phase motor only runs if I pull the belt bit stops under load.

    Sounds a lot like the start winding is cooked. Not really a diagnosis job for the inexperienced or those who lack the required test equipment.

    Electronics Boffins needed

    Yes, as I thought. Circuit is crap.....needs redesign. See what I can do...hope you're not in a rush.

    my french 1 h/p single phase motor only runs if I pull the belt bit stops under load.

    In place of providing a number of pics of the same view, how about one or two of a panned out view. Is the motor as built or have you dismantled it?

    Electronics Boffins needed

    Outline the way in which the circuit is supposed to work in your opinion. I have my own idea but it may not be correct.
