Another Valve dilema!!

Hey there, i really need some help!

I purchased a TSL 60 about a month ago and it was running fine until today. I can get absolutely no noise from it at all. Upon further investigation i noticed that the heater for one of the output valves wasn't working. However when i replaced the valves with new ones the heater worked but there was still no sound.

Does anyone have any ideas what the problem could be, i'm desperate!

Could also be a fuse. The JCM900's have a fuse for each pair of output tubes. Might also be the output transformer, could be a cap...maybe a resistor. Could be a lotta things. Since it's a month old bring it to a service center and get it fixed under warrenty.

Also, a good rule of thumb to follow is that if you lose a tube for whatever reason shut the amp off fast and replace the tube or get it fixed. The longer you run an amp with a bad tube the higher the repair bill will be. If you lose the output tranny it's really freakin' expensive plus it's a huge part of the amps tone. It won't matter much with a TSL but a Plexi or simple amp like a Naylor will sound vastly different with a different ouput tranny.

Thanks for the advice Jay, taking it back to the place of purchase for a straight swap, might be tempted by the mode four though! The new marshall solidstate amps. Anyone heard any good sounds from them?

I just finished an album for a band a couple weeks ago and the guitar player brought a new Marshall Mode 4 w/ "matching" cab and his old JCM 800 with a 1960 cab..................
the 800 kicked the Mode four in the grillcloth and made it say "uncle"
I've never really liked solid state Marshall anything.

The store I'm quitting is a Marshall dealer. I played the MF the first day we got them. There are four channels/tones. One of them is kinda sorta useable... maybe.

Marshall and solid state...nope. I haven't heard the Mode 4 but after recording too many Valvestate amps I'm not really going to go out of my way to hear it either. I'm also not a fan of the TSL amps, the DSL's are way more usable IMHO.
