Hi. Bought a bdi21 the other day 2nd hand and it works fine with batteries but with a replacement power supply dedicated for it , it doesn't work. Any easy way to fix this ? Thanks

Use batteries? Is the power supply the correct voltage and does it supply the needed mA? Are you sure it's the right one, and that it's working?

Not exactly a fix, but it should work.

Thanks, I assume the clip connects onto the power adapter. Is it a 1mm or something, to connect into the 2mm female .

Place the barrel of a Boss style power supply into one end, and clip the other end to the BDI21's battery clip. Simple as that.

This is a known issue w/the Sansamp copy series. You hook up a power supply w/greater than 100mA power, and it no longer works with a battery, and vice versa, stuff like that.

Mine only works with a power supply, same happened to me GDI21, but somehow now it only works with the battery clips, so I just hook up a power supply to that.

These are really only valuable bought new, because they partially break so easily.

wirebrake = easy fix?

Thanks guys, really appreciate the help. I'm Gunna use it to warm my tone up a bit so it will be in constant use hence the lack of battery appeal. I will give the 1 spot adapter a crack. I could take it apart and have a look but I'm ham fisted and likely to destroy it!

I had this very problem. It worked last time I used it, then I reworked my rig and went to plug it in and it was dead except if I used battery. Just to kill time and tinker a bit, I did a lot of troubleshooting. the input jack is fine, solder connections are fine. What I think, and I could well be wrong, is that there is a protection device that has failed between the adapter input and the battery input. Just a guess because my troubleshooting without schematics is not particularly good.

However, I chose to do a hardware mod and hardwired the terminals of the power adapter jack to the battery terminals on the board. Works as intended again, though now the safety feature isolating the jack input and battery input is now disabled.
