I brought my Reeves custom 6 home from work, and now it is making some noise. The amp fades in and out, not fading out all the way, but I'm not getting a full sound, or a really good sound for that matter. A snowflake could've fell into one or both of the inputs when I carried it to the car. I don't know if that would be the culprit. I've swapped out the preamp and power tube, plugged into a different cab, tried a different cable, and now I've air-dusted the amp and put deoxit on all the good parts. I've got to let it sit for the night now. Any ideas of what is wrong or anything else I can do? thanks.
