    Can I split an 8 AA battery holder into 2 packs that still generate 12volts?

    Erm.....Not sure I understand that. And as already stated by Harold, it's 12 volts not current! If you have two battery holders, they have two connections or wires. A black negative and red positive wire. You can simply just join the first box red to second box black. Then you left with just...

    Can I split an 8 AA battery holder into 2 packs that still generate 12volts?

    Hi Doc, Yes, you can easily use two sets of battery holders. Or any combination. The link you provided have a 'type' of battery holder with a switch. Probably not ideal, because you need two. Anyway, the basic explanation is all the batteries are series connected. That means the + from one...

    Radiogram, no sound

    They sound much better values. Seems like the meter was faulty or you were reading it incorrectly. Over to you Bob and Edd. I am following this thread as I want to learn about valves too.. Martin

    I think @Bluejets is getting close if there is no sign of a thermostat!. Why don't you email Whirlpool and ask them? It might be quicker than replying here and getting 'professionals' out. Or strip the whole unit and show us everything without the whites!! Don't do that!:) Martin

    How to calculate R and C for Am Demodulation envelope detection?

    It would appear your question has already been answered on another forum! The equations were there too. 39nf and 5.1K Martin

    How to calculate R and C for Am Demodulation envelope detection?

    Hi Bilal12, Firstly, I would cheat! As the equations turn my brain to mush! I would stick a 1K and a 1nf to start. Or a varistor. And adjust the cap. Maybe 5nf 10nf. But have a read of the books as the equations are all there. Martin

    Kenwood sat nav DNX5280BT keeps rebooting!

    When you collect it, hold it in your hands and ask for the Kenwood documentation for the repair! Ask what the problem was! Then you can barter over the price. I would be fuming!! Keep us updated Martin

    Is that at the back near the top? If it is, the thermostat is behind the panel. You will need to remove the panel... Martin

    Where to buy (low cost) electronic components?

    Hello, I use Ebay (via China, Hong Kong). Very cheap, but sometimes 10 to 15 (or longer) days delivery. I don't mind the wait, I order quantities of components. So once you have the first delivery, it's easy to keep stock. Check Ebay for resistor pack...

    Whirlpool would be the ones to trust!! The place that you turn the temperature down is the thermostat. It's behind the panel at the top. Martin
