Subject: [BITX20] Killed TX this time...

?

... so my fun continues!

Running some tests with antenna tuning on the MJE I seem to have blown the finals or I thought I had, no watts on any band except 40m into a dummy load. Replaced the finals with two RD16's as I had wanted to do this anyway. Now testing not getting any output on any band. Note v6 has a second set of holes for the reversed pins.

Checked have 12v on final legs, on TX one gets 3.8v across the legs and the other about 4.2v across the legs.

Confirmed D8 gets 12v on TX on 28MHz and the others D11,D12,D13 all show zero volts which is expected.

Checked drivers and all show circa 0.65V and pre-drivers show 12v.

Reception is working fine but definitely not getting any output, any thoughts on what else I should be checking ?

Thanks!
