[Hallicrafters] sx101a

[Jack Schrader]

Strange question from someone who has a degree in electronics but here goes. My sx101a worked fine on the vintage net this past Sun. but the next time I turned it on there was nothing. No sound & no s meter movement. 

All tubes seem to lite up. Changed both audio output tubes but still nothing. Thought I'd ask before I take it out of its bottom cover.

Thanks Jack
