[QUOTE="Ampdog, post: 44919, member: 144"] About all has been said, but this appears to have been overlooked. I presume the power supplies were the same, circuit-wise. If so, what is the difference in layout/placing/whatever between the two? It is true that position is important, and it is just your 'luck' if the best position is somewhere at an odd angle in space. I had that with an E-I transformer in a valve circuit (Partridge no less) and the thing was just about useless. On the other hand, in the 'Thalia' I placed a 200VA C-core tranny right between the main amp circuit boards (mounted vertical) without experiencing problems. Ludo, No, the spot-weld is unlikely to cause perceivable problems - the discontinuity is insignificant. An in-situ examination with a flat 'search-coil' on the end of an oscilloscope probe is a handy way of determining where the transformer leakage flux is worst/best. [/QUOTE]
