Hello friends,
need some help.
I own a Kairn with a round brilliant sps that is near to die.
Its serial 1612. So it was updatet years ago from linear transformer to that round brilliant sps. I own both now, the brilliant sps(not working) and the linear kairn transformer, i want to use now.
Question: - is it possible to go back easily and set the linear psu instead of brilliant sps?
- Does anyone know the voltage on the secondary side of the linear psu? is it the same like round brilliant? Ther are loose cables on the linear psu.
- Do i have to change the rectifiers or something else?
PLEASE HELP !!
Next days i upload some pics of both psu and my fix of accu on the dislpay side

I recently fixed my Karik brilliant psu and followed the guidance here:
Linn Brilliant SMPS - naked! - pink fish media

Linn Kairn - how works it without Battery ?
The Linn model LK-1 (preamp) works fine even without the 3V6 NiCd battery resp. accu, but follow defaults I note after switch-on:
1) Volume control is "0"
2) No source is selected (mute).
This is good to handle.
By the model "KAIRN-PRO" (without elements on PCB at the phono RIAA section) I read follow after switch-on in the display:
"err2- don't panic innit!"
After this I read under "Volume" the value "0" and after a second it runs up to the value "50".
The selected input (listen) is "tun" (TUNER) and no record input is selected.
Is this behaviour correct and in accordance with the default settings without battery?
Are there other unwanted effects present without battery and is the battery (in opposite to the LK-1) under all circumstances necessary ?
I ask this, because sometimes (not often) the display goes death (even the two strokes are missing), although music is to continue listening. But commands (e. g. volume control, input select and so on) are no longer accepted.
After switch-off and switch-on again it works like previously described.
Thank you for your advices.

Kairn Screen sometimes going still blank after replace 3V6 NiMH Battery
Now I have replace the battery by a new version, but I still observe the same, as mentioned in my post #1. But all other functions are correct.
This effect with completely dark display occurs unfortunately not often, so that I am not able to perform a troubleshooting.
That reminds me of a frozen screen on my old personal computer while work on it.
I assume, there must be a PIN at the processor, which is very sensitive against spikes on the mains. The internal power supply isn't the SMPS-Version (Brilliant).
Thanks for any advices.

This can happen if an old NiCd-Accu is only removed too late
Check out the images below of several through corrosion-oxidized vias on the prozessor board so as the time-intensive work to eliminate the resulting contact problems.
On the threaded bolt of the alu front plate paint residues must be removed for trouble-free electrical contact.
Check out the images below of several through corrosion-oxidized vias on the prozessor board so as the time-intensive work to eliminate the resulting contact problems.
The main reason therefore are contact errors at the plug connections between mainboard and front- (operating-) PCB (at whole four connectors) and between the aluminum front panel and front PCB (GND-screw).

Volume level "0" instead "50" wanted by swtich-on without NiCd/NiMh battery
Yes, this behaviour is correct - it is present at all devices of this preamplifier model from Linn. Now rises up the question, how I can change this condition after switch-on without battery for memory-buffer. My wanted condition is the same as by the model LK-1 without memory-battery.
Are therefore an other EPROM-software necessary ?

I have a Kairn that when turned on the green LED glows, dimly, but nothing is shown on the display. I don't think the amp works without the display but have not tried.
The PSU, slimline Brilliant, seems OK as it works inside a Karik.
The battery pack is leaking but on first glans I cannot seem much if any corrosion. The battery is still outputting 3.6V
Could a battery/corrosion cause the fault?
Is this the slimline Brilliant PSU?

An externally hosted image should be here but it was not working when we last tested it.

Hello,
I have an good Linn Kairn Preamp from the 1990s. Suddenly the 3.7V Battery died and did destroy some lanes. I managed to restore the lines but somehow the Eprom lost its memory.
There is a Sticker on the M27C256 "AE31-LK2V00-25/11/94"
Is there anybody who could send me a *.bin or *.hex file for burning? - I have a Programmer and clean 27c256.
Thanks
Robert

Linn did send me a *.abs File. I don't know how to handle it. It doesn't look like hex. Can someone help me to get it in hex so I can burn it on the EEPROM the right way?
Is there a Tool that can convert it?
The *.abs File is like this...

After restoring the ROM I still had the same Problem. Green LED was ON and nothing showed up on the Display. My Slimline Brilliant SMPS brings something like +/- 20V and 10V.
After checking my restored lines on the Front-Panel (Battery damage) I found one more little cracked line. The one going from C2 to Q3 was cracked right at the hole to the opposite close to Q3.
So if I had checked all the lines before I could have saved a lot of time recaping everything... But now it should be good for the next 20+ years
If someone needs the ROM file please feel free to ask... Or is here a Spot where I can Upload it?
Wrap it in ZIP format and Attach it to a post.
ZIP ensures integrity and also "hides" the unusual file extension (not known as 'safe' by the forum upload tool).
You might also include a TXT file saying what it is, what it is for, and any tricks you know about using it.
