Thank you for viewing. This is a TAMRADIO power transformer PC-182 for vacuum tubes, 180mA. Input: 90, 100, 110 V Output: 330V, 300V (180mA), 5V (3A), 6.3V (7A), 6.3V (1.2A), 6.3V (1A) Approximately 13.8cm high, 11.0cm wide, 8.0cm deep, and weighs about 4.0kg. I have confirmed continuity between terminals with a tester. Applying 100V, all terminal voltages are OK. It is a used item, but I believe it is usable. I would appreciate it if those who understand the above would consider purchasing. Thank you for viewing.
