Commander 1250 HF Manual

[WA2AAR]

Hi All

I hope soneone can help me out. I have a Command 1250 Amp. I am looking for the USA manual for this amp. The one on the internet is for the export one. uses all 5 terminal in the rear of the amp. The USA one only uses 4 terminal. I want to connect the amp to 110vac just to run it. With no RF going to the amp at all. I want to check the HV in it to see if all is well before I put it on line it is now wired for 220. I will use it on 220 when I put it on line.
Please let me know if you can help me out.

Thank You

The export model has a 200v tap for use in Japan. If you now have a jumper between 2 and 3 (you should if it is on 240 now). Then the process of elimination automatically tells you that you should jumper 1 and 3 and 2 and 4 for 120v operation. The 5th wire in the export model is the 200v tap that yours does not have, it is marked pin 4 so on the US model pin 5 becomes pin 4 because the unit is void of the 200v tap. Anybody disagree?
