Hello,
I recently purchased a used Mark IV rack mount version. Before purchasing I asked the seller to verify it was working on all three channels via a YouTube video (due to distance) in the video all things checked out so I bought it. Get the amp delivered to my house, plug it in and no sound....verified all cables are functioning, verified recording out on the main volume was not pulled. All volumes are up...even removed tubes and reinstalled (except for the sheilded pre amp tube) even tried plugging my guitar into the effects return and still nothing...lights are on, tubes are glowing.
Amy help is greatly appreciated!!
