Mine was blowing Rec tubes. They suggested a Copper cap SS instead of tube Rec. I haven't had any problem since. My Fender amps have original Rec tubes in them from when I bought them in the 70s. For $2K, I am not sure why this amp is high maintenance. One of the reasons I got rid of the...

I still don't see a link to the mods. Am I missing something??

So did you check the cable to make sure it has continuity? Or is it in the box? You have 3 conductors in that cable, so it can switch 2 different things. Also, there must be another 12AX7 cascade gain stage added when you kick in Solo, check your 12AX7s.

I would caution not using the non MB matched tubes. The amp can go into runaway, stress the transformers, blow the fuse and a Rectifier tube. I went to one of my local music shops. I needed what I thought was 1 tube since I was using it in 5 watt Class A mode. Well their version of...

LSS and Strats SCs and P90s. Vol pot swap mod and Reeder mod. ch2 is great OD now. And don't use any other pedals either. They dampen the tone.

He might be fine for this mod. I am also miltary tech, but had a Stroke and did it with no problems. VR, Ron

What about taking the back off your Speaker cab and making it an open back? ron

Or non MB matched power tubes. They can cause the LSS to go into Runaway and blow fuses, melt wire coatings or cook the transformers. Was the reduction mod done on it? Ron

I found out the hard way, you need to use MB matched power tubes, other brands might let the amp go into runaway and blow fuses, burn wire and transformers. Ron

It doesn't look like this is for the Lonestar Special? If so are ther pictures and dialog for the mod in English? VR, Ron

Take the back off your speaker cab?

J200george, Did you figure out what was wrong with it? What wattage are you running it? 5 watt is tube rectifier, 15 and 30 are SS Diode rectifier. I you flip to stand-by and change wattage, and it still sound not loud, it is not the tube rectifier. Probably 1 of the 12AX7s not a power tube.

I was told by MB that the Class a powere designis proprietary to MB. Not your single tube Class A, but a pair of the EL-84s are involved. So there is a slight push-pull tube pairing to this Class A style.

Or qrap the tube base with some heat resistant tape, so that the retainer bites it better. The tubes with broken key can be fixed with...

I have an LSS and the pick attack is what I like, but using the 5 watt setting and tube rectifier, it is melodic. I also have tinnitus. One of the resons I use 5 watt. I don't need more sound energy, just nice OD with 3rd order harmonics for that sweet old school roundness to the pick attack...

A great bunch of people.

djw, I would have to agree. Some pedals don't have boost to them and end up sucking tone from the guitar signal.

Take it to your local MB authorized repair station. You can find them on the website, or send it back to the factory. It is reasonable labor and it will be returned working perfectly. There is some mods for reducing the current through the tube Rectifier, but if you are not using the 5 watt...

They are loaded with sturdier transformers and porcelain sockets for lasting longer than I will ever play it. Very True.

YellowJacket, the issue is I accidentally got a groove tube EL84 in there. It Red Plated took a fuse, Rec Tube, and the Power Tube. I sent it to Mesa Boogie for Repair. Only Mesa Boogie Power tubes should be used and the pairs should be matched.There is a Current Reduction mod that involves...
