Part 2: 🛠️🪛 How To Install a Zeus Speed Controller For Your Linn LP12 Turntable

[@lloydstephens2135]

I bought the Zeus internal power supply for my Linn Majik LP12 after watching this video several weeks ago. Thank you for sharing the video. It made installing my Zeus upgrade go pretty easy. The power supply is a big improvement over the Majik power supply. The tachometer feature makes it a real bargain compared to Linn’s Lingo 4 power supply.

1:38 Hi Dave great vid. Last year I purchased the External Zeus speed controller, you will receive a box with a speed display and a normal Valhalla 33/45 Switch and it’s perfect

Fantastic product and Steve is a wonderful person to work with, he is so helpfull

[@MODAC]

I'm glad you had a good experience!

Hi Dave, I chose the Vinyl Passion PSU for my 1990 vintage Valhalla replacement. Very happy with it and now enjoying 45rpm records too. For my sub-chassis and armboard, I went the Stack Audio route, with their cast alloy, Alto parts. They absolutely transformed the sound, totally eliminating the bloat in the bass which these decks were famous for. I also installed the Stack Audio base plate which comes with three height adjustable damped feet. So much easier to level the plinth. I’ll be done once I have an Ekos II arm fitted, but need to save up for that! Thanks for the video and keep up the good(!) work 😄

Awesome. I have been talking to Stack audio and we may be doing something. I considered VP, but Valhalla were much more accommodating. Thanks.

Just beautiful to watch and finally the realization "I am not alone" Thanks for this very entertaining episode and only the best, Sammy

Ye man. your diy vids are inspiring me to maybe someday try some of that kinda stuff!

[@MODAC]

Go for it. More to come in the future!

Thanks much for the video and especially that link! My real interest was in whether this power supply could be fitted to a Linn Axis, and if you're aware of this entry level turntable I'm sure you know they're NOTORIOUS for having power supply problems. Looking at the Valhalla web site, they offer repairs and upgrades to the Axis power supply (WOW???!!!) at what looks to be a very reasonable price, even fixing the common annoying problem with the Axis where the turntable will start spinning after power is lost and restored! I'm surprised they even offer Axis repairs, as I'd given up looking because at the time mine went flaky about a decade ago, I'd found almost nobody was willing to touch them at the time. After getting my Rega Planar 25 I didn't part with my Axis mainly because I literally couldn't give it away at the time despite trying, maybe now it can be brought back to life! I'll contact them soon and will mention you when I do!

It's possible to fit either a Minos or a Zeus to a Linn Axis, but the motor on the Axis power supply needs to have some wires soldered to the motor coil connection lugs. The Axis switch may require soldering too depending on which version of Axis you have. Alternatively, as you mention we can just repair your Axis PSU 🙂

[@terrybeavan4264]

@@valhallaelectronics4055 Thanks much for your reply, I do believe I'll get the old Axis out and have a look. Having you all repair the PSU sounds like a great idea! I'd bought mine used some years ago and it had supposedly been serviced and had the bad capacitors replaced, and shortly after getting it, it developed an odd issue I haven't seen mentioned anywhere else, where every time it lost line power and had it restored (which happened a lot since I had it on a power strip I'd turn off whenever I wasn't using it--anyone living in Florida understands why LOL!), it would run just slightly faster each time until it was noticeable and annoying. After about 3 or 4 times adjusting the speed (not so easy to do since it's only accessible from the underside, and yes I used a plastic adjustment tool knowing of the voltages lurking in that supply!) and worrying I could be getting near the end of the range of adjustment I just put it away and gave up on it. After watching this video and looking at your web site I'm very interested in reviving this otherwise great sounding turntable!

Hello Dave , I don’t own a LP 12 so why did I watch all your video? Because it was it was a good one and to the point, maybe one day I’ll get one ,

[@robertgreene1946]

The Zeus is a great power supply upgrade as good or better than a Lingo4 and you save over $1000 I have the outboard Zeus on my LP12 and I feel it is the best power supply I have had on my LP12. I had Mose/Hercules, Mober DC psu. Put one on your LP12 you will be very happy.

[@tonyjedioftheforest1364]

Looks like a nice unit but too complicated for me to install. Have you seen the Hercules unit which is much cheaper and I believe is easier to install? I have the Majik PSU and an adapter for 45’s but don’t use that, I have a second dedicated turntable for them which is easier for me to use and I can use a conical stylus on that one which is very kind to surface noise on older records.

[@MODAC]

They sell the Minos which is similar to the Hercules.

[@tonyjedioftheforest1364]

@@MODACI forgot to add that you aren’t using the trampoline baseboard which is very inexpensive for a Linn part and I am told makes an improvement to the sound. I can’t comment on that as mine came already fitted so I don’t know how it would sound without one.

[@MODAC]

@@tonyjedioftheforest1364 I’m using a lightweight British metal stand. I read that you if have one like mine the Trampolin is not necessary. However, look out in the future for future additional mods and upgrades.

[@ingenfestbrems]

So it should monitor the speed 33or45 times a minute..

[@ingenfestbrems]

Why not installing a DD motor

[@MODAC]

That would be difficult and ridiculous

[@ingenfestbrems]

@@MODAC no ultimate upgrade

[@NateEll]

Don’t doubt it works but seems a bit of a kludge

[@MODAC]

Not really. Once it’s installed you’re good to go. You could go for the Linn Radikal 2 with a similar tachometer feature, fancy motor, etc. but it will cost you.

[@NateEll]

@@MODAC running the tach cabling through the bearing space just seems like an awful idea. And btw, much the same technology but in an AC motor form is available in the Lingo 4 which is far cheaper than a radical. Like $3500 cheaper

[@MODAC]

@@NateEll they sell the external Zeus, that does more than the Lingo, and is $836…less than half the price.

[@watdanuqta-mf5ms]

@@MODAC @MODAC Ah, you're misinformed, the Lingo IV has a tachometer that controls the rotational speed plus a 12 volt AC motor that is inherently quieter than the original and a more sophisticated outboard power supply. If you touch the platter while it's rotating, the on/off switch led gets brighter until the correct speed is attained and it's dead on accurate as measured with a KAB Speed Strobe that displays numbers directly on the Disc, Operates with Dead-On Accuracy(an uber cool device if you never used one). You still using your phone? The Radikal, uses an expensive DC motor and two different and sophisticated power supply choices that I'm not sure is better than the Lingo IV. DC motors have their inherent problems and to get them working well doesn't come cheap. VPI uses one in one of their models and it costs them $5,500 a piece. Kind of a lot of money to get the accuracy that asynchronous motors do for a lot less and the fact that Linn's motor in the Lingo IV runs at a tenth the voltage, typical of AC motors. It's running at a typical DC motor voltage. The Zeus is built to a price point and it shows in the design, so we're not comparing apples to apples. I'm curious, Do you even understand why the Valhalla supply( its operation) was an important design and the difference between the operation of an AC motor and a DC type? Oh, and are you still using a third rate phono preamp with your LP12? You would be surprised or maybe not at what a better preamp can do. Reply

[@travelllller]

You want to tell me that for the price this thing does not have speed controller built in? I guess this is a joke.
