The great equaliser

This model is very SEX-y! :)

Mend it mark a UK YouTube electronic fixer is one watch to repair old tech https://youtu.be/UpctKF-rhHE?si=IGeMJEoInOgHSNqB

I think the equaliser looks absolutely gorgeous. I have a Philips VR-2350 Video 2000 player which uses a very similar styling. It’s not quite as special as your Tefifon, though...

It looks similar to my kenwood ge5010. But this one has more functionality than mine. I might have to open it too. I just got a Sony seq d707 which I think is more similar to that on functionality but is the smaller midi format. Just because I thought it looks beautiful (display) as the kenwood is not very colorful. I used to think I was a bit of a weirdo by liking the displays... And to be honest I only so often activate the eq function... Then nowadays I only have so many opportunities to listen to music without children shouting and running about

So lovely to see your music-based entertainment center again in a video <3

Good onya mat! Nearly wet myself when you told them what they can do!

The Graphic Equaliser / Spectrum Analyser argument has always been an eye rolling conversation for me 🙄 1. Unless you have the exact room, system set up and volume of people which were in that room at the time, then it’s never going to be the same as the producers intended. 2. If I want to fiddle with my music, then I bloody will do. Great little video, Matt. Thank you, Lee

I also like having a graphic equalizer / spectrum analyzer in the system, even if the EQ function is switched off just to enjoy the dancing lights 😉

Great idea using a battery compartment. :)

Battery replacement is a fun thing. Trying to solder a new battery in place is not fun I have found.

Your music. Your ears, Your Toys. Your RULES! PS I like the music by Antony Copens as well. Very interesting~

Neat! (or 'leet' as the case may be!) The flip top battery holder was a great idea.

Good lord, your hi-fi is Epic.

I enjoyed that! Thanks, Mat.

You have a very nice setup. Congratulations. The tefifone flex gave me a nice smile :)

You make an excellent point about room size, shape, furnishings, different components etc have as much or more effect than a graphic equaliser. I think we can all agree that so-called audio”philes” can “do one”.

"As far as I'm concerned, both they and the horse they rode in on can go and do one! 🤬🤬 Anyway 😊" I was thinking that this was the most relaxed I've heard you in a while until that last part. 😆 I share your stance though, and congrats on the fix; neat machine, neat video!

That's a beautiful part, I'm really happy you were able to fix it! Smart-arse-me feels the urge to ramble on about soldering techniques, feel free to skip if you're not in the mood for it! I can see from here that the two solder joints are cold-joints. In this application probably not really an issue (the only one I can think of is them breaking due to vibrations), but I'd recommend learning the proper technique, as it's not difficult. You can find online tons of resources, this video for example is concise and accurate (no affiliation): https://www.youtube.com/watch?v=Qps9woUGkvI In this particular case, you'd need a third hand to use the technique described. That's when one can generously pre-tin the parts and add some liquid flux before re-heating and joining them.

I wonder if those piano keys at a slight angle are common to Technics, as my cassette desk of theirs has them too? I'd also regularly check normal batteries in remote controls. I found the ones in my HD-DVD remote had leaked as I hadn't used it in ages. Could HD-DVD be a topic for a future video or is it a subject with not much to say? We could have another pub quiz sketch!

interesting part#

Next time I trip over the pronunciation of Matsushita, I'll think about what I'd say if I needed to ask you for a bit of peace and quiet: "Mat, shush. Ta".

"It's all about the fun." Indeed.

Really great battery mounting solution to ensure should any future battery go bad (hopefully not), it's nowhere near the board.

Just Another Excellent Video, sir.

Did you know you’ve caused a run on Yoto’s?

SEXy thing you've got there ;-). The battery issue I know from various synths, luckily those Lithium cells are not so prone to leaking and causing damage, still replacing is always a good idea!

Great looking setup Matt!

Had a moment where my stomach sank when there was mention of a battery backup in this thing. I was relieved that this had a happy ending, with a really nice fix. Plus, I learnt about the difference between BR-2032 and CR-2032. Lovely little vid for my Saturday morning. Thank you!

There aren't many things more important than a new Techmoan video.

Glad you used a battery clip rather than remove the PCB. In my experience - and I've repaired several of these and other similar kit in my 40+ years in the repair trade - those "Brittle" connectors you refer to are actually quite OK, even after all this time. It's plastic casings you need to be wary of.

Great video. I just love when people complain about the 'purist' audio and how music should be listened. By definition a home music system is "contrived," that is, it is to be listened to artificially, (speakers, headphones, etc.). Honestly, no one system will ever sound like the original. It ultimately comes down to the subjective mindset of the owner. And if that person likes the setup, then it's just right. It still reminds me, when I was quite young, of visiting my parent's doctor friend who was an 'audiophile'. He had multiple thousands of dollars tied into MacIntosh preamps and amps, and these huge Klipschorn speakers that were like placing two refrigerators in the living room. He then demonstrated how great they were by playing a record of train locomotives.

A beautiful device that also seems to be quite easy to maintain. Ordinary button cells with spot-welded solder tabs are quite common, so the battery could actually be an original part. Anyway, you fixed it nicely.

Great video. I have a graphic EQ/Spectrum Analyzer with a very impressive 14 band display that is LED based (no fluorescent burnout issue here). When the battery gave up the ghost, I replaced it with a 5.5 farad super capacitor which is continually topped up whenever the unit is plugged in via a tap in the power supply DC line and voltage dropped with a 9.1v Zener diode in series with a 470 ohm resistor. Should keep it's memory for after months of being unplugged. Love the commentary about audiophiles. Many of them seem to think that mixing & mastering engineers are gods w. perfect ears. "For creations stability! Don't change the settings of the studio-gods with an equalizer in the loop!" they all seem to exclaim. I do mastering with some extremely sophisticated tools and the AI side of things knows that equalization is one of the areas where human engineers screw it up OFTEN. The goal is to make the end sound profile acceptable for high quality mid-high end equipment and do so in such a way that common shortfalls of audio are PREdicted & augmented in the master. I explain it this way on the website: " Q: The Spectrelayer’d versions seem to have a slight tonality bump on the extremely low & high ends? Why is that? A: There may be several reasons you are hearing unanticipated level differences on the spectrum ends. Rather than pretend that we live in a perfect world, -Spectrelayer acknowledges that we don’t. As a result, Spectrelayer uses statistics to create a tonal curve that addresses the most common limitations of audio hardware & human hearing in advance; – & has made it possible for the end listener to achieve the best sound for their unique system by mildly tweaking only (2) tone controls: The Bass & the Treble. The primary reason that some people may need to adjust the Bass & Treble is that the extreme ends of the audio spectrum are where most weaker-tier components reveal their shortfalls. Many loudspeakers roll off the high frequencies abnormally – dulling the upper harmonics (hello Bose). The same is true about the Bass end of the audio spectrum. So Spectrelayer creates balanced, dynamic tonality curves that anticipate human hearing aberrations & playback hardware shortfalls. Because Spectrelayer preserves bit-depth to reproduce nuances – there is often audio data available to describe the subtleties in the dynamics of the low & high end that the ear can indeed resolve if the recording contains these cues. And, since it’s better to cut too little of a tonal range than too much; -Spectrelayer is comprehensive regarding these factors & takes steps to work these detailed nuances into the mix by adjusting the overall tonal distribution on the audio spectrum. This approach has (2) effects: People hear highs & lows with better detail & clarity than ever before in recorded material; -& audio systems that may normally suffer from internal limits – sound better than usual. If your sound system already resolves the ends of the spectrum with great clarity then simply adjusting the respective tone controls will provide the level adjustments (up or down) that you need to best enjoy the Spectrelayer sonic signature. How Spectrelayer deals with these common shortfalls is complex. Adjusting for your unique situation after the fact – is much simpler. Once made, the adjustment tends to work well on all Spectrelayer’d content." In other words, I master knowing that rudamentary tone controls are ALWWAYS good to have available and equalizers are powerful tools for shaping audio to the uniqueness of your sound system.

• Splendid fix - very accessible for future users, too. • These devices are gorgeous in use - once upon a time I desperately wanted a graphic EQ. Currently I'm more worried about food and expenses. • I love seeing your hi-fi. It's a thing of beauty and I can live vicariously. In fact, instead of an 8 hour video of a fireplace at Christmas I'd prefer an 8 hour video of your hi-fi. Take care 🤍 & 🤍

I owned this thing when I was a teenager and just loved it. Looking forward to watch the video.
