Need Help with Boss DD-2 Adapter

[TexMax]

hey guys,
i have been lurking here for quite some time but this is my first post.

can anyone tell me the correct power adapter to use with an old blue label Boss DD-2? i have researched enough to gather that there are serious concerns with polarity/tip grounding/voltage issues, but i have not been able to find the straight dope on what the actual specs of the adapter need to be. i got this pedal in a swap a while back and really like it but boy does it sure go through 9 volt batteries quickly and i would hate to fry it by using the wrong adapter.

thanks!

Standard PSA power.

Mine uses the standard psa but i believe some of the older ones use aca. Should be a sticker next to the power jack.

thanks guys,
the sticker says PSA. i just wanted to make sure as i got a little worried about all the polarity/tip grounding/voltage issues, with some of the info saying the older pedals take 12v etc etc.
too much information perhaps?!

yeah the older 12v Boss's will say ACA for the power.
