[Elecraft] PR6-10 - no gain on 10

[gt-i at gmx.net]

Hello list,
I bought a used PR6-10 and realized it does not provide any gain on 10m 
but does so on 6m. I already checked the DIGOUT1 configration per band, 
as well as the jumper setting (off) inside the PreAmp.
Anything else I should look for?
