I live in Sweden and wonder where I can get my SF-2 repaired? Just before an imortant gig power in it went and now itīs stone dead (exept for the front lamp thatīs lit). I just canīt live without it = only "effect" Iīll ever want/need! Pix from our gig at www.flickr.com/photos/ankhljufer. Iīm grateful for any advice. best regards from a frosty sweden mica Moderator Username: mica Post Number: 3206 Registered: 6-2000 Posted on Monday, April 03, 2006 - 9:08 pm:    Usually, this is a problem from using the incorrect polarity on the transformer. There is an illustration printed near the connector to remind you to always use one with a center positive and the voltage range is from 10.5-17VDC. To test if the choke has failed, use a voltmeter to ground, and you should see the same reading on both sides of the choke (ie 16V on both sides). Here's where to find it: It looks like a resistor, but it is a 47mH choke. If you can't find that exact part, you can use a 1/10 watt fuse instead (never exceed 1/2 watt). Or, if you are really brave, and need it functioning in a hurry, you can use just a wire, but understand that the choke protects the rest of the unit if the polarity if wrong. If you eliminate the choke, a more expensive repair will be in your future if the same thing happens again. albrecht Junior Username: albrecht Post Number: 29 Registered: 8-2005 Posted on Tuesday, April 04, 2006 - 2:57 am:    hi and 1000 thanx for your promt reply!now my technician can fix it quickly. i just canīt do without it. itīs the best thing that has happened to my basssound (well, having to epics is nice too!), thanks from sweden. albrecht Junior Username: albrecht Post Number: 30 Registered: 8-2005 Posted on Saturday, April 08, 2006 - 2:25 pm:    all is well in the albrecht-house! the sf2 has a new choke. micas information was vital for speedy service by my tech. exellent!!! iīm happy!!!!! davehouck Moderator Username: davehouck Post Number: 3599 Registered: 5-2002 Posted on Saturday, April 08, 2006 - 4:55 pm:    Cool!! I've found that it is a good idea to mark wall warts with a Sharpie. I fried a perfectly good answering machine when I plugged in the wrong wall wart.
