Golden Eagle,, No Key ??

[fm969]

Does anyone know which is the key up tube for the Mark 3 ??

Was in perfect working order and it just came from the eagle man in Alabama, was completely gone through.

Went to grab the mic and it keyed for a split second and now nothing..
Is like the mic is not plugged in,,, nothing.
tested another mic,, nothing.

It has got to be a tube..... ???

What do you guys think ??

Before you start replacing tubes you should open the rig, and do a visual inspection, might be something as simple as a broken wire.
