This is an Alinco DX-70TH hf rig I repaired for a local friend. He bought it at a hamfest as a "non-worker". Good receive, no transmit, VERY high idle current. I suspected finals... When I cracked it open, there were loose screws all over, main board loose, cables disconnected, etc. Oh well, sure enough, the n-channel FETs in the PA were hosed.
I put everything back together, removed the FETs, and bypassed them with .01uF caps as a quick test. Nice QRP rig, did about 4 watts out. Beautiful signal, and proved the rest of the rig to be OK. I replaced the FETs, and it was a new rig. Here's a few pics...
