What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Retro HiFi Two-in-One video

This video features two devices, The first is the Realistic APM-200 - an external add-on VU meter sold in the 1970s & 1980s through Radioshack and Tandy. The main subject of the video though is the Onkyo U30 - an RCA Switchbox/Pre-amp. 

I really don't see why an enterprising manufacturer couldn't bring back either one or both of these types of devices. If they were to go a step further and add in a DAC, then we'd really have an handy all-in-one HiFi component. Perhaps I've just given someone the idea for a Kickstarter.

What a great find!

I'm wondering if you could do a video on cleaning old hifi equipment. Yes I'm sure I could do a few searches myself but you have such a collection of retro hifi equipment I'm sure you had to do a bit of cleaning on it all.

I've recently picked up an old cassette deck which needs a bit of a clean but am not really sure what I should be using.

Thanks for all the great videos, you first helped me decide which dashcam to get and now have got me interested in audio again!

Maybe a switchbox is all well and good for a retro hifi system, but it's a bit different for a retro gameroom setup, you're going to need at least a mid-6.1-era AV receiver that has enough analog A/V ins to connect all your consoles to the TV, and still get decent audio output quality.
