Hi, i am a newbie in this forum, and require help on my Logitech Z-2300 2.1 multimedia speaker system. My Z-2300 toroidal transformer have died and i need a replacement. But i do not know the VA rating of this transformer.
I was also able to gather the following information from the net:
Transformer Details
Manufacturer: Ten Pao International Ltd.
Model No: TOG433028F0
Input: AC 230V/50Hz
Output: AC 20.1V x 2
Diameter: 95 mm;
Height: 45 mm.
Amperage: Unknown
VA: Unknown
I opened my Z-2300 subwoofer and clicked some pictures, which i am posting below:

Based on the size - I would guess that this one is about 120VA.
But I don't know since Z-2300 is capable to deliver 200W RMS & 400W RMS peak power.
Z-2300 Specifications
Total Continuous Power(RMS): 200W
Total Peak Power(RMS): 400W
Also Z-2300 amplifier uses
i) Two STMicroelectronics Class-AB, 80W, TDA7295 amplifiers bridged together to provide a total of 2 X 80=160W for the subwoofer.[Assumed]
ii) Two STMicroelectronics Class-AB, 60W, TDA7296 amplifiers powering each of the satellites.
So, do you think since it powers 4 TDA chips, it is 300VA rather than 120VA considering its size?
