Marshall DSL40C "small issue" Advice on upgrades ?

[JPB]

Ok, so roughly four months ago, I purchased a Marshall DSL40C amplifier. The amp was purchased new.

Anyway......

The amp probaly has about 200 hours of playtime....usually mid gain / lower volume levels inside the house. Two days ago, I plugged it in, let the tubes warm up as usual....hit the standby and good to go. But nope. I heard slight crackle noise....which may have lasted all but two seconds. Then I head a single pop noise. Then, regardless of what I tried, it had no sound. Whatsoever.

Looking in the rear of the amp....The two power tubes .... One is like the one on the right, and now, the other one looks like the one on the left in the pic. I have read online...particularly here http://blog.thetubestore.com/how-to-tell-if-your-tube-is-bad/.

This isnt my pic, but these are identical to mine. Both were like the one on the right. Now the right one is normal looking, and the left one is white. Just like the pic below.

Anyway, this post is for more of a confirmation of a bad power tube....AND advice on upgrading the pre amp tubes.

I want to upgrade the pre amp tubes also. What I play, is mostly.....80's early 90's style. Anything from Guns to Nirvana.... But I want a warmer sound. The stock DSL40C is too bright for me.

I want more of a Slash November Rain solo tone.

My current guitar is a Schecter Solo II

- Bridge Pickup: EMG 57
- Neck Pickup: EMG 66
- Ernie Ball Regular Slinky #2221

Pre-Amp Tubes -- Please recommend

Speaker Upgrade -- Something in Creamback ? Or a Vintage 30 ? It is quite possible I could be picking up a Boss ME-80 as well.

Any advice on pre amp tubes ?

experiences like this are good to remind us why we don't use tubes anymore

There are gonna be a lot of amps come and go in my life. But right now, just want to upgrade this one. Advice on which tubes or speaker ? Something about the Celestion Seventy 80, just rubs me wrong.

And by the way, how the heck do I get this "imported" off of my user name ?

If you purchased it new 4 months ago, isn't it still under warranty?

 

[JPB]

In my location, since it will be around $200 to send this in...I do it myself. At least that way, I know what is going into it. And I doubt under warranty they would "upgrade" the amp anyway. So at least if I do it myself....I know what im getting back. I never deal with warranties.

So...recommendations on a new speaker and pre amp tubes ?

my serious answer would be to ask somewhere else like http://www.avsforum.com/forum/90-receivers-amps-processors/

It's a guitar amp, not a home theater amp. I'd find a good guitar/musician forum.
