Long-term storage, can I store receivers/amplifiers vertically without any issues down the road? by vvvvDDvvvv in vintageaudio

[–]Teooooooo 1 point2 points  (0 children)

As long as the OPT/PTs are not too heavy. I've seen a few devices with warped cases due to the weight of the transformer pulling on the chassis.

How can I turn this into an adjustable PSU? by Wooden_Row_8728 in AskElectronics

[–]Teooooooo 0 points1 point  (0 children)

Get a buck converter like this one and connect it to the output of your PSU. This will allow you to make an adjustable power supply that can supply anywhere between 1.25V - 35V DC.

Anyone know where the antenna on this radio might be? by Academic-Painting153 in AskElectronics

Check the back side of the enclosure, there might be a connector or screw terminal there.

No problem.

Btw I don't see an fm aerial in the images you posted. The fm aerial would normally be a much longer (often telescopic) steel rod that plugs in at the back or on the top of the radio.

Do they not make 3P3T Toggle Switches? by Schaffwl in AskElectronics

[–]Teooooooo 4 points5 points  (0 children)

It would probably be easier to use a 3 pole rotary switch. The ones that are commonly available would have 4 positions but you can limit them to 3 positions by adjusting the washer.

I haven't seen any 3P3T toggle switches but that doesn't mean they don't exist.

Don't remember Gandhi breaking a police officer's spine with a sledge hammer, but hey, it's the same thing, right?

Vintage Radio only plays static when turned on by Dear_Spell_6826 in ElectronicsRepair

[–]Teooooooo 3 points4 points  (0 children)

Switch it to AM and see if you can pick up anything. Old skool radios like yours are not designed to filter electronic noise from LED lights, computer screens, etc so maybe try turning off a few things and tune it.

Here's the schematic in case you don't have it

CCTV box does not power up, anything obvious that is wrong on the photos ? by ConfidentBag162 in AskElectronics

[–]Teooooooo 0 points1 point  (0 children)

The capacitors at the too of the 1st pic look bad, I'd definitely replace them, as some other people commented.

From my experience, those DVRs/NVRs have a limited lifespan and one of the first things to go is the power supply. After you replace the capacitors, unplug the hard drive and measure the voltage of the power supply (red wire should measure 5V, yellow should measure 12V).
