I've got a Toshiba M-5900 VCR and it's transformer is turning finger
burning hot.(Some screws darkened also)

Since the 2SD1273 transistors were making noise, I replaced them with
TIP121, with a metal case. The collector got shorted to ground.

At the repair shop, they changed resistor fuses and STK regulator.

The VCR works perfectly apart from that.

At least, the VCR components aren't dead, the PSU wasn't plugged to
the rest when it blown.

Should I replace the 2SDs if I can get some 2 for 7$ + shipping?
The channel selector near the preset tuner is also producing whine.

What I'd like to know is if other M-5900s are producing whine near PSU
and preset tuner(door on the top), and if it's really hot over the
PSU.
