I recently purchased a swan 500c, according to the seller in good condition, but had not the power supply. I have a Henry tempo of an old one (yaesu ft200) supports this power supply with swan 500c? I have been looking for the characteristics and voltages seem to be correct, but I have no info intensities. I measured the voltages on the power supply of one tempo a -118, 352, 670 vdc. in the voltage of 300VDC in the swan 500c what is 325vdc max in one tempo I have 352, with load, when they should be 300VDC. not if it is a problem of the source of one tempo or so. my question is? I can put the swan 500c in power supply one tempo? thank you
