Here's a tale. On our way to a new gig about 30 years ago and the van blew a head gasket. Managed to bump start it and managed to get to the gig. Set up and sound checked and it sounded perfect. The stage looked perfect as well. 26" Double bass drums, all chrome kit and on a riser. Two double 100w Marshall stacks for bass and 2 Marshall 50w half stacks on flight cases for guitar. It didn't get any better than that.
played the gig to about 20 people who really enjoyed the band but the place was empty. Band played well though.
Loaded up the van and went to get our money. No cash only a cheque for £20. That would be about $60 back then. No matter what we did or said, they would not give us cash.
Back to the van and tried to start it and it wasn't having any of it. Cylinders were full of water. Luckily? one of our roadies had driven himself to the gig in his Reliant Regal van. 5th picture down, http://www.3wheelers.com/reliant.html
the darker blue one.
So there are 6 of us plus guitars in this little, 3 wheeled van and the broken van with all our gear in it stayed at the gig.
The following day I arranged to have our broken van towed home by someone I knew, who owned a Land Rover and did recoveries. The next day as I was waiting for our poorly van to return home, I received a phone call from the police.
"Do you own this van only we've found it wrapped round a telegraph pole with the back doors open".
Dashed out to see what had happened and sure enough, there was the van crashed into a telegraph pole a load of our gear was missing, strangely enough, it had been taken out in the order that it was loaded and what was missing was enough to fill the back of a Land Rover. Even the disgusting drum carpet had been taken. It would have covered the gear nicely I recon.
I never saw the bloke that towed our van home again. Strange that. Got the van home and fixed it and tried to get the gear back together but it was never the same.
Is that the end of the story? not yet there's just a little bit more. Remember the cheque that we were paid with, you guessed it, it bounced. When back to the venue to confront the landlord and the place was all boarded up.
I think that if all you need is a new set of valves/tubes you're lucky.
