Linn Solo Concern

Hi Chris

here they are sitting side by side. 

let me know if u need another angle ;-)

Very nice and clean setup 

Plenty of air above… no question.

As you said, fans begin at 75 on the pre.
It's higher than my experience with Solos… so the air above works in your case, so your Solos are OK for me…

The things to make an even better cooling:
1 – No LP under the Solos to refresh the wood plate in between,
2 – not very esthetic, but some sup foots that elevate the 3 boxes, to let the air pass under…

As the LP covers are made of paper, and are very compact in the 2 shelves, they should keep the heat.
And I'm pretty sure that this heat return to the wood then return to the Solos…

You have to try! Tell us

This might be a cheap experiment to try: place the solos on each side of the DSM/preamp. That way you don’t have two heat producing pieces next to each other.

Part 2 after separating the solos try raising them a few inches just to check if air under them helps with cooling

Check the temperature of the cases. Maybe the thermal paste is not fitted correct (unlikely that both solos have this problem).

But as mentioned above: 75 (of 100) is very loud.

Relocated two shelves of vinyl so will give this a try and report back.

75 is loud about 92db. Separated out on either side of DSM and at 73 fans on after 15 mins. Bottom of units are hot to touch - uncomfortably so.  Bringing vol down to 70 and fans stayed off for 20mins. units still hot.

it’s seems to be around what you said at the start of the thread. Maybe a proper rack with some slats to let air in from below would help. 

challenge is the fans are so noisy especially when both are on and the volumes been dropped down. Picking up with my audio guru and dealer now I’ve tried a few things and see what Linn say. 
 

thanks all. 

 

[AlbertF]

Sorry 75 more like 96db. Maybe not good for extended listening

I'm with you… sometimes, we need it to be loud! Some tracks need it too

Enjoy your system long term, maybe conservative but worth considering

I have 8 solos through 2 Klimax Exact boxes into Isobariks. When I purchased my last two solos, the fan consistently started up on one of them after maybe 20 to 30 minutes running at about 70. My dealer took it back to his shop and ran it in his demo system. It did the same there. The offending solo was returned to Linn as faulty. It was fixed under warranty within a couple of weeks and has been fine since. I have no idea what the problem was, but it is fine now.

I have also experienced other solo fans cutting in when the ambient room temperature has been very (unpleasantly) high and also when they were stacked a more restrictive space.

However, from your photographs there should be no reason why the fans are cutting in. They are well ventilated (assuming the ambient room temperature is not excessive. I suspect there is a fault that requires Linn's attention, after perhaps running the offending solo in your dealer's system to double check.*

* Before doing this I also physically swapped the offending solo between upper / lower bass, mid and treble (I can't recall which) to see if the fault followed the solo. It did.

Hello AlbertF,

what are the serial numbers of the two Solos?

If they are between 653049 and 789974, there is a possibility to reduce the high heating of the amplifier by a transistor exchange.
The instructions are from LINN and must be carried out by an authorised dealer.
(Linn part no. RES 047).

Thanks 

serial numbers are way much higher than the range.- only built in august - but who knows could be similar issue

Hello,

I had a deeper look on the A4200, and it tends to confirm the idea that amp is actually missing cooling below the case not above. Assuming the Solo works in the same way, the idea from Zee9 to uplift the case must helps. Also having them on a wood plate don't allow the heat to go away as wood is isolating. 

I'm trying now with elevated amp, and as next maybe about using an aluminum plate as base to help the heat to dissipate around. 

Back to the measurement: the cover temp is around 28 to 34deg. But the bottom side is around 32 to 40deg. The fans seems to start when the bottom side rise 38deg and cool down till it is back to 36deg.

=> So 38°C (100°F?) seems to be the limit to avoid fans, at least for the A4200/0. This is warms, but not HOT. Most probably the Klimax case has a different limit, but might have allow issues to cool the bottom side.

Regards,

Antoine

I have my devices elevated with pieces of ikea günstigs as pictured. $7.99 a piece at ikea and then cut to size. On older linn gear with the shorter legs (a/c4200) I use two pieces stuck together with crazy glue. These also help with vibrations.

Adsm/3 >> Akurate 4200/1 >> Majik 140’s (Silvers/K400)

 

[zee9]

Maybe I should start using double pieces on all the gear.

Having one layer of Gunstigs is helpful.

2 layers improves sound quality even more in my system, and 3 layers is better again.

Paul, have you tried eight levels? This should have an huuuuuuuge impact.

Even one layer has an impact, so I recommend to try if this goes in the right direction. If yes, there is no reason not to build towers .

I’m sure you are correct. I’ll get right on it.

You know it makes sense…

 

[Paulssurround]

Let me think about this for a second:

‘Let’s spend €2000 per Time Table Platform for each Linn component, or €4 for a Gunstig, from IKEA, which will give you much of the benefits of what the Time Tables do for mitigating vibrations?
