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%!

Active Speakers with built-in Vinyl Pre-amp

There are a surprising amount of items I’ve had to buy over the years to make videos. Some of these things won’t ever be seen on screen like the camera, tripod and lights, but there are many others that make occasional bit-part appearances like power transformers and extension leads. 

The speakers shown in this video have been bought to assist in the making other videos. Almost any audio device, can be connected to these powered speakers including those with bluetooth, optical output and most importantly record players, whether they have a built-in preamp or not. This not only makes these ideal for my needs, but also suitable for anyone working with limited space who wants to minimise wiring clutter.

The Roth VA4 speakers are Available from AMAZON in the UK 




In the USA - KANTO sell speakers with the same features

Always enjoy your videos. In particular, the ones that focus on vinyl. I work for a small shop in Austin Texas that services and sells vintage audio gear. Much of which centers around turntables of course. Many appreciate the vintage turntables. Many of which are hard to beat in terms of quality and performance. Especially for the money. Many of our customers don't have the space or budget for a large vintage amp or receiver. These powered speakers offer a great option, especially in the shrinking living spaces here.

With all of these small inexpensive amplifiers out these days, I am still puzzled why none incorporate a phono stage. Some of our clients already have speakers, or wish to use some classic ones. I know such a thing would sell very well. Currently, you have to spend about $300 US for an amplifier with a phono preamp built in. I am sure one of these "class D" amps could be combined with a phono stage for half that.

I really like the turnatable you show with this demo, what kind is it? Looks like a good spacesaver

It’s a Project RPM 1.3 Genie. I really didn’t like it though. Too flimsy.

What a fantastic piece! Many thanks, I`m currently thinking of purchasing Roth VA4 speakers. I called Roth direct for clarification as whether I needed to put a phone pre-amp between the turntable and the speakers but was greeted by someone who had to put me on hold whilst they went away and discussed with one of their colleagues . . . . HELLO-OOOOO! I was talking to the Technical Department!
This video made everything clear, many thanks. I shall buy.
