There is a red and a gray wire running to and from the reverb, does it matter which is connected to the input and which to the output? The reason I ask on my Twin the red is connected to the input, but on my Deluxe ReverbII the red is connected to the output. What kinds of problems could a reverse connection cause? I never touched the connections so as far as I know that's the way they came from the factory. The twin recently was recapped and retubed, but I'm sure the tech knows what he's doing so I can't imagine him mixing them up.
Thanks for any responses.
