hi Mike,
of course, if I can find any spare licon switches, I'll tell you about it. But I have been searching, and it seems there's no more of them anywhere. And it is perhaps more tricky to find one in France.
We just have to wait until a new old stock of these appears on eBay... maybe one day.
So if you find a source, let me know too !
I have repaired mine (thanks to Stevem's advices) it works almost perfectly, but I think one of these days I will have to replace it for a completely different one.
Regards
Phil

You are better off to buy a doaner head or amp that is trashed or beyond repair or the naugahyde is to far gone that has a good switch.

This is a good idea, but maybe not so easy to find for a low price...

Hi guys, It's been a long time since I've commented here but I also have acquired a K300 PA with missing switches. After reading about this, I found this link. I am not in a position to measure the dimensions of the original Licon switch, but this might be a suitable replacement. http://www.e-switch.com/product/tabid/96/productid/51/sename /d16-series-illuminated-pushbutton-switches/default.aspx#ex1
See what you think. Kind of like the old purple Kustom (Dialight) lights in the older series, you can get the switches with different lens colors, if you so desire. There is a PDF specification that you can download and it is very detailed with every option you can imagine. I think this would be a great replacement.

Thanks for the link ! I think that's the kind of switch that could be a good replacement option. But I think there are 6 contacts on the original Licon instead of 4 here. So I guess it should be rewired in a different way.

Hi Phil,
First off, I would ground the chassis and eliminate the polarity reversal switch. That method of hum elimination has branded more guitarist's lips with the screen of a microphone than any other. E-switch also has a pilot light that looks exactly like the switch it compliments. I would put that in the polarity reversal switch hole and just wire it to light when the amp is on. The power switch only needs to be a SPST switch but E-switch only sells a SPDT switch. By removing the polarity switch, you only need to apply power to the transformer. I see that you are in France and usually mains switches are 2 pole, one for the "hot" and one for the "neutral". I looked at the diagrams at the bottom of the PDF and noticed that the switches are not actually a true SPDT configuration but a double acting switch that opens 2 contacts and closes 2 contacts when the switch is pressed. In France I would assume it would be best to use a DPDT switch. You would then use terminals 3 and 4 on each section for the black and white wires. I need some help from the guys who have the K150, K250, K300, K600 series amps as I have not had the opportunity to check out my newest acquisition. I'm mostly familiar with the K100, K200 series amps.

Hi Conrad,
thanks for the details.
I have replaced the power cord for a three-wire and grounded the chassis. This was because I sometimes got little electric shocks and did not feel secure with it. Now it seems to be perfect. We commonly have the network wired with ground in France, I have put a ground wire everywhere in my house so this is not a problem, but of course this is not the same everywhere !
For the moment the power switch still works, it is broken inside but I have fixed it with a nylon strip to hold it in place.
Perhaps it will break one day, and this is why I am looking for a spare. But I will keep your informations safe for the day it will happen !
I did not have the opportunity to try several Kustom amps as they are pretty rare here, but I can say that my K-150-2 is probably the best solid state amp I've ever heard. I had a Lab series L7 combo that was really good but unfortunately it was stolen, and I own an old HH IC-100 that is good too, but to me the Kustom has a lot more attractive sound, the tremolo/vibrato is fantastic and the eq section is very effective and musical, the bass controls is really powerful, it can deliver tons of bottom end, and I am experimenting to use both channels simultaneously, so the eq section is really amazing. Unfortunately I do not have the original cab, but they seem so big and heavy, I'm happy with my 2x12 Engl cab loaded with Celestion V30.

Hi guys ! It's been a long time since I wrote my last message here. I'm still searching for the licon switch and I have put an automatic search on ebay. Here's what I found today :
h t t p s://www.ebay.fr/itm/LOT-OF-TWO-01-740081-LICON-SWITCH-PUSHBU TTON-FULL-SIZE/142953303356?hash=item2148ae4d3c:g:1AMAAOSw0I tbq-Ri:rk:2:pf:0
The part number is not exactly the same (01-74081 instead of 01-74122) but it looks VERY close to the Kustom power/polarity switches. I wonder if this one could work as a spare (I will have to find the lightbulbs too).
If someone could tell me if it's good (the switches are quite cheap but the shipping is very expensive: 23 USD !!!) so I need to be sure before I spend the money.
Maybe this could help Mike, if he's still searching too...
Thanks a lot if you can answer !
Smile

Hi guys!
I have switches that will work, they are not 100% original looking but very close.
95 % of the time you can fix your old busted switch without even picking up a soldering iron, all you need are 2 cable ties.
Call me if you want to try this repair first as my replacement switches are not cheap at 70 bucks, but I guess there cheaper then buying a donor amp!
