[Elecraft] KPA1500 fault

[Eric Swartz - WA6HHQ, Elecraft]

Hi Steve,

When plugging in the large 50V power cables between the power supply and rf deck, make sure they are pushed in firmly with -two- distinct insertion clicks. After feeling the first click, push them in further for the second click.

We are finding some customers mistakenly think they are fully inserted after just the first click, which can lead to intermittent 50 V to the amp. 

If you still have problems after checking this, please contact support at elecraft.com so we can help you resolve it.

73,
Eric
