Hello, I have a question about power transformers. I wonder whether I can use the following substitute transformers: A. 9V+9V ( 10VA) instead of the 'stock' 9V+9V ( 15VA) B. 15V+15V ( 25VA) instead of the 'stock' 15V+15V ( 30VA) A (9V+9V ( 10VA)) is rated at 0.55A. B (15V+15V ( 25V)) is rated at 0.8A. I checked the manuals. Buffalo II needs 290mA, and IVY III needs 150mA per rail for the total of 300mA. It appears B supplies more then double of IVI III need. However, A is oversized only byabout ~47%. Can I use both A and B instead of 'stock' transformers?:  My primary goal is size/weight management. Thank you in advance, Dmitry Edited by user Sunday, September 19, 2010 7:14:46 AM(UTC)

Those transformers should be fine.
The 9+9V will be 0.55A per secondary, which you would use in parallel, which doubles the current - so it's actually 1.1A
