I am also looking for information, specifically a schematic, of this unit. The one I have is actually a Trio W-40 but I believe it is the same. It has a problem of overheating a resistor in the power supply.
If I come across anything, I'll send you a note and I would appreciate the same from you.

Hi,

Not much of help I know but for what it is worth:

These companies are one and the same.

Increase the wattage of those Rs in the PSU and it will last for
ever.


Cheers,;)

Hi,

Well...I tried that but to no avail.

Also I looked through Sams' Photofacts library,no hits either.

It's just a wild guess but the following could happen due ageing:

1.A cap in the PSU may have dried up overloading that resistor.

2.The resistor itself has changed its' value.

Cheers,;)
