Which one to choose?
Hello again, I updated my previous post as the power demand from the dc side will be 1.27 times the ac side ............... Alternately, contact Logitech and see if you can purchase a 10 pack of these transformers for future required replacements
MrAl, thanks for your great insight. It really helped me out to come to a conclusion. The only thing that I currently know about my Z-2300 toroid is 2 X 20.1 V.
From a local transformer manufacturer, I got the following choices of toroids to fit in my Z-2300 :
1) 120 VA --> 2 x 20 V, 3.00A
2) 120 VA --> 2 x 22 V, 2.72A
3) 160 VA --> 2 x 18 V, 4.44A
4) 160 VA --> 2 x 22 V, 3.63A
5) 225 VA --> 2 x 18 V, 6.25A
6) 225 VA --> 2 x 22 V, 5.11A
7) 300 VA --> 2 x 18 V, 8.33A
8) 300 VA --> 2 x 22 V, 6.82A
Now, I want to know which one according to you will be the best replacement? Which one to choose? I am a novice in this field, and though I am an engineer(IT), I have no prior knowledge in audio field.
Just think this Z-2300 is yours, and what toroid you have chosen to fit inside it. I am impatiently waiting for your reply.
