I have a pair of Dared 300b monos and sl2000a pre. I usually leave the tube gear on 24/7 unless I'm going out of town. I'm dog sitting for a friend and his hound drooled on one of the tubes while I was at work today. I came home to find both monoblocks shut down with a broken tube in one of them. The light on the power supply was off but the switch was on. The power supply will not turn on at this point. I installed different tubes and neither monoblock will turn on. Any ideas?

Thx...Chris
 
Chris, I'm sorry, but I really laughed alot reading this.

Didn't the hound get electricuted ?
Maybe it's an alien, having acid in it's drool :D

Let's get serious.

What do you mean with broken tube ? Did the glass break ?

Can you show any pictures or schematics ?

When you disconnect the damaged monoblock, does the other work ?

Dick.
 
Dick, et al


The glass tube was broken, shattered. I pieced together that it was indeed hound slobber. After some close investigation I noticed the bloddy hound spit all over my amp like a *******' Llama:drool: I changed the fuse in the PSU and it works, powering up the other monoblock just fine. I cracked open the damaged unit and needless to say it is royally screwed. Resistors exploded like popcorn, melted caps, the whole bit. I said the hell with it, had a stiff libation :drink: and ordered a pair of Dared VP20's. Now I'm left with one 350b mono @ 6w and a PSU...is there anyway to utilize a single flea power mono?

Ahh, this story is further evidence that one should not leave tubes burning 24/7.

Hi,

You can always cut off one ear if you're desperate enough...after that you'll probably start painting like a madman but hey...Why not?

Anyhow, what makes you think the broken channel can't be fixed?

Ahh, this story is further evidence that one should not leave tubes burning 24/7.

Nah...Only that it would be wise to keep tube amps above "drool level"....
Which is probably why you see so many high-end gear on "static display" during shows....:cannotbe:

Cheers,;)
