Removed from a YAMAHA Dual Cassette Deck - part of the Natural Sound Series
YAMAHA AC Power Input/Stepdown Transformer
Ex Yamaha KX-W302 Dual Cassette Deck
Part # XE634A0
Hardware mounting screws onto the power PCB is included
PCB pins solder direct to the power PCB
ONLY 240V 50Hz input - this transformer does not have multiple primary windings
Secondary winding is centre tapped
Iron E core complete with the original mounting frame
Dimensions: 60mm x 47mm x 43mm height
Weight: 500g
Measurements:
Working fine prior to removal from the equipment but double-checked the transformer after removal
Using 240V AC input on the primary, Secondary output (no load) is 12.5V - 0 - 12.5V
In other words the TOTAL AC output is 25V
This is a fully electrically isolated transformer, NOT AN AUTO TRANSFORMER!
IMPORTANT NOTE: The primary PCB pins number 3 but only two are to be used as the "3rd" pin is directly connected to one of the other pins (the two "outer" pins are connected together) - to accidently connect the 240V to these outer pins would result in practically a dead-short! Not good.
I looked carefully at the former but cannot see any pin number designations. I have very clearly indicated on the former, the primary side and pins for connection of the 240V input on the former (white dots)
COSMETIC CONDITION:
Very nice condition both electrically and physically.
Clean and undamaged
PCB pins have NOT been shortened
Since removal from the equipment, I have now placed this transformer and the associated mounting hardware (screws) into sealed plastic
