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.

Realistic APM-200 looks great, any chance to find out what are the dimensions?

Perhaps Techmoan wants to find a new home for his APM-200? ;)

Hi Mat,

Another interesting little titbit...(we're from the same era I think and I love all that audio gismo gear as well) I use a Realistic mixer SSM-2100 for most of my connections, plus 3 different amps to power speakers all around the house...two of which were second hand.

I re-decorated a few years ago and it took me all afternoon to re-cable the things back together.

Amazing tech - keep it coming.

As always thanks for listening....

Hi mat, another excellent video!

I didn't know that ONKYO but it looks awesome. I love it. However, I'm done with my dbx 400x signal router which does a similar task except that it doesn't have any meter and doesn't manage a phono or tuner.

My unit can manage up to 3 decks, 3 external sound processors and a noise reduction unit, which I find perfect for my needs. It works without power but if you connect it, the buttons light up. This way I can connect my Technics 12-band SH-8020 unit EQ, my BBE 422 sonic maximizer and a dbx 3BX-DS for the crossfeed effect. Then I have all my noise reduction units (four at the moment: Dolby Reference 422, JVC NR50, AIWA HighCom and Toshiba AD-4).

For metering I use the Nixielyzer which I find lovely, although a bit expensive and very difficult to build up.

BTW: I sent you a PM through youtube, did you see it?

Keep doing excellent videos ;-)

I forgot there was a way to do PMs on youtube -I've just had a look and there's hundreds in there, whoops.

I'll email you back separately.

I've had my eye on the Nixielyzer, it's just a pity it's so expensive (and the base is overly fussy) - it would look a lot smarter in a nice reflective chrome block with all the writing and buttons hidden around the back.

Raf, I'll try to get you the measurements tomorrow.

February 10, 2016 | Registered CommenterTechmoan

Very kind, thanks a lot. You wouldn't want to part with yours by any chance, would you?

February 10, 2016 | Unregistered CommenterRaf

Raf, I don't really need the APM-200 now - but it did cost me £90.
The approximate dimensions are
Width - 22cm
Depth - 11cm
Height 9.5cm

You're so right, i would give an arm and a leg to have a real equalizer like the one i'm using with winamp on my pc.

Nobody clever enough to make it and trow it on kickstarter?

Mat, thanks a lot.

Re. the lack of blue film on the replacement bulbs, years ago I was changing out the dash bulbs in my VW Scirocco and found a type of bulb paint that allowed me to convert my dash illumination to a very BMW inspired red color. We also recently rebuilt and restored a 70's era oil "rain lamp" and used yellow bulb paint to saften the bluish hue of the LED light that illuminated it.
