Huge Black Box - Power or Output?

[Zben3129]

Hi Guys,

Just got a "100w stereo amplifier" at a yeardsale for 4 dollars, made by nikko. I opened it up, hoping to find tubes, none there. There is a giant black box, though. I am wondering, is this a power transformer or an output transformer? Marking is TKP0137-2     T-1-332


Thanks

  What's it hooked up to?
  Probably a PT, see if you can trace the wiring  to AC input, [output iron is often a forgone pleasure for SS designs], unplugged isn't necessarily 'safe'..figure out amp safety conditions before going inside an amp with HV.
  I typed 'draining filter capacitors' in google, and found

  Information on amp safety.
Potentially lethal voltages require understanding amplifier filter cap conditions, read..before you proceed.
If there's only one transformer, it's probably a PT.

If there are no tubes there, it's most likely a power transformer.
