[Amps] THP HL-2.5Kfx

[William Liporace]

I appreciate the help...

It was not the OPER/STBY switch. It is actually a DPDT and only using 
one side. I went ahead and moved it to the other side. Both sides are fine.

I was also told that there are two fuses just above the caps. I checked 
them and they are OK.

The only thing I was told to do is replace the firmware chip. Does 
anyone have the file and or a chip available?? Any help or suggestions 
would be great!!!
