I'm sure of it! I had a gig last Friday, we were the first band out of 4. I played, then took down all my gear and set my unracked, open SWR SM 900 on the back far left side of the stage, out of the way with the amp turned around on the speaker. I wanted the amp to cool off before I put it in the Samsonite suitcase I use for transporting it. When the night was over, I placed it in the suitcase and took it home. Yesterday, I go to set it up again at rehearsal and find that the power fuse & CAP are missing! The local music store wants me to order from SWR, 6 - 8 weeks. A trip to A-ONE electronics has me sifting through boxes and voila, a new fuse and used cap for $3.50. Slap it back in, power it back on and were ready to rock. BUT MAN!!! I might have been screwed for awhile.
