I did had a quick search and found this: https://www.partco.fi/en/electronic-components/passives/resistors/flame-proof-resistors/12325-fres-05w-5r6.html … so I’ll either go for that or the TE Connectivity one that I linked to earlier.

Ha, Partco is my local (finnish) component dealer and this is the exact part I bought and where I got the part earlier 😀 I guess they do ship abroad too, but it might get costly…

(Again; I am not sure if this is 100% perfect part for this, but as the service manual doesn’t really give any details and the listing says flame-proof it sounded good to me and I used it for testing and was mostly astonished to find the LC2 working again with only this fix).

Ha, thanks! 🙂

Thanks for that Lausvi – sounds promising! R3 is also 5.6 Ohms but it’s on the top side of the board near that white bridging wire (hidden by the IR module in my first picture). Did you find/fit a flameproof equivalent/replacement?

Ah, now I had a look at the schematics and indeed there were two 5.6 ohm resistors. I believe I had to remove the IR module to get access…

My local dealer had one listed as a ‘flame proof resistor’, which appears to be a SPRX1/2 by Koa. The datasheet states: ‘fixed metal film, Flameproof, Ceramic Body, Flame Retardant Coating”. This was as good as I could get at the time.

In any case neither of the LC2s are in use, and I was planning to recap those anyway if I were to use them again…

I’ve had two cases of a dead LC2, and both times it was the 5.6ohm resistor (although my notes say R3?) that had gone open. No burn marks or anything. Both units work now.

Hi – and welcome to Beoworld!

The bog standard 9V adaptor should work. I’ve heard 9V 2A been recommended (the original as pictured, appears to be rated at 500mA). The plug should be center positive, and physically it should be slim as otherwise it won’t fit into the crevice.

I believe there was no circuitry inside the stand, so you should be able to verify if the 9V is going to the contacts on the top of the stand.

Thanks! And extra thanks for doing the schematic!

I’ll need to get the rest of my LC1s out and check those diodes! I had luck reviving at least three I think by just replacing the lithium battery.
