[Elecraft] K3 KPA3 Failure

[rfenabled at gmail.com]

Has anyone had a KPA3 cause the display to show ERR 12 v?

Power supply checks out normal as do the leads. The circuit breaker is in line and does not drop out.

Connections appear ok as does the antenna system which is resonant etc.

When the error is displayed the K3 reverts to low power 12w out max.

Resetting does not correct the fault, tried placing the KPA3 to bypass and all works fine. Changed the setting to PA nor and the fault returns immediately.

Support have been notified by e-mail bit thought I would ask the group if anyone else has had this happen and if so, was it a KPA3 failure requiring replacement. Of course the warranty has expired...(:-((
