There is also another possible issue to consider in that the 847 when first powered up sends a full power transmit for a very short time.
Could be this is the missing link explaining why i burn 2 preamp in the past? but i always put the power knob at minimum when i turned off the 847. I will have to test it as i measure about 5W even if the RF power is set to 0!! Full power i'm not sure but even 5W is enough to kill a preamp
