On the bench, arrived today, a nice SM-900 SWR amp head. It's swaeet except it doesn't output audio :? Doesn't even output noise. thats why it's on my bench. Anyway does anyone have a schemo for this thing? I am trying to avoid calling SWR as you can never get anyone on the phone over there.
time to start figering circuits. Tube preamp with solid state output statge. I'mn not so sure about that plus @ first glance appears to use a voltage Quadrupler to get the necessar B+ voltage on the tube hmmmm this thing is start to not me so sweet anymore. I thin would have been beter off al tuber or all solid state :?
