[Premium-Rx] RE: HF-2050 power supply and cooling

[Paul Wende]

Hi Larry,

As Walt mentioned, check out the archives, there is a lot of good info there
...but to save you some time... The way I did it worked out very well and
was so easy...

The power supply transformer has multiple taps for the primary voltage
selection...just change it so that it is set for the highest line voltage,
i.e. 125 or 135, whatever it may be, this will reduce your secondary voltage
to the regulators and keep things cooler.

Good luck,

Paul

Recently purchased a Collins HF2050. Which is the best way to cool the power
supply? Muffin pan pulling  the air from the top or pushing the air from the
bottom?
