power transformer - 1200mA or 1600mA?
9 Answers
Hi - I have an mp3 speaker kit which has a mains transformer rated at 9volt 1600mA. The transformer has broken. I have looked for other transformers, but the highest mA I have found is 1200mA. Would this still work with the speakers, or MUST I use a 1600mA?

Part No LO6BR it can supply up to 2500mA,it can be set to various voltages so you would need to select 9, and as stated before you would need to ensure correct polarity of the output plug.

builder .... not quite
the transformer (psu) feeds the amplifier .... the amplifier feeds the speakers
mystic
(this is an over simplification) .... but - the psu delivers a variable .... but constant current to the amplifier based on the volume it needs to deliver .... and that's the problem .... because of the constant drain ... the psu will get hot HOT HOT
ianmunt's suggestion is spot on the max current @ 9v=1700mA ... so good call
