I noticed that the 2 PSA adapters i have have extra letters on the end of their code name.
PSA-120T
PSA-120TW
I predict that it has to do with the country as Taiwan's code is TW.
Anybody else have this too? |

and an old one ACA-230G
No idea where the P and G stand for. |

Boss PSA-240 (no extra letters, 2 screws to open the case)
Boss ACA-240 (no extra letters, no screws - sealed case?)
Both marked as Made in UK, both bought around 1987/88.
Was it only adaptors, or did any pedals ever get made in the UK? I imagine not. |

| that seems odd to me nosiO, but just remember that the power pedals like tu-2 and psm-5 are only rated for 200ma. |

whoa, you had me scared for second, I use to run my bcb-60's 1000mA to the NS-2 to add extra pedals via a second daisy chain, and thought you meant it can only handle a load of 200mA. The reference to the maximum of 200mA is when using a 120/220/240 adapters with the combination of all your pedals not to exceed the current draw of the adapter, which is 200mA. Using a RPW-7 you can get 700mA, used for rack mounts.
the tu2, psm5, ns2, and ls2 spreads the power, not provide it |

Actually, Boss doesn't recommend sending more than 200mA through the TU-2, PSM-5, NS-2, and LS-2, and I'd be careful as well. There's a small circuit board connecting the two power jacks, and the traces that carry the power from the DC input to the DC out/thru jack are quite thin.
You're right about the theory - those pedals do not provide any power, as they merely pass it along. But I'd feel a lot safer using the power through jack for higher-current applications if the jacks had been connected with wire instead of (very) thin pcb traces.

It was Boss itself who listed the RPW-7 with 700mA as an example in the NS-2 manual. I checked 'cause pedals4pv mentioned it can only handle 200mA and was worried i may have fried my ns-2, or could have but was lucky at the time i did it. I added a roland daisychain to the ns2's dc out to the other pedals in my bcb3. Now I just use another daisychain on the last plug from the bcb, from where the mini tuner suppose to go
I never even heard of the PRW-7 before, I had to google it, only to find it's meant for rackmounts. Weird they would list it under the NS-2, isn't there a rackmount noise suppressor? Maybe only the NS-2 can handle a larger load. |

| It must be just the NS-2 I downloaded the manual and checked and there it is. I have a psm-5 and Tu-2 and power 15 pedals with 2 psa-120s. I reread the manuals for TU-2,PSM-5 and LS-1 and I can't find any mention of a 700ma supply in those. I don't have a noise supressor on my board, maybe from a subconcious fear that it will render my playing mute. |

I searched the forums, and it seems that there still isn't an answer to the question about the additional letter on the PSA adapters.
In Germany the models that are sold are named PSA-230G, PSA-230P and PSA-230S.
Does anybody have a hint about the differences in these models?
They all look the same, and are rated at 200 mA. |

| The "S" is the new switched mode version. |
