Hello, My Lonestar Special keeps burning the tube rectifier and fuse. Every other week or so. I understand that Mesa offers a mod to avoid this situation but I am not in the position to send the amp to Mesa for modification since I am in Romania. I tried various tubes, I ordered from TAD and...

To me, the most shocking experience was to see that the clean channel and the drive channel sound the same if the drive is disengaged and the Thick/Thicker/Normal switch is in the normal position. And of course, it became hard to get a sound that I actually didn't like. I have no idea how this...

In the mean time I installed a fan inside. Kept it on for 2 hours, no change in the sound, it is perfect. I also talked to a friend of mine who knows electronics, he told me that the culprit may be a tantalum capacitor in the cathode bias that changes capacity because of the heat. The fan is...

Hi guys, My Mesa Boogie Studio Preamp sounds superb when I first turn it on and it does sound good for at least 20 minutes or so. After that, the lead tone changes in that the low end gets really undefined, I loose attack and bite. Clean tone remains ok. I changed a lot of tubes, pretty sure it...

Hi, Unforunately I only know that the capacitor in question (the one that my post is about) is a ceramic 1000pf or 1nf. The original capacitor is 5nf 600 volts so the new ceramic one should have at least the same voltage rating but I think you will be fine with a 800 or 1000 volts as long as it...

I haven't tried other than 6L6's tubes but I can tell you that changing the capacitor at the input at the drive stage like I did and explained in my posts will not change the clean channel at all. Yes, Lonestar classic cleans are beautiful but sometimes they lack that hugeness... My way of...

Just a quick report on this topic, I modified all my Lonestars, including the Special. The 1000pf (1nf) capacitor seems to be the best. So, the one with the 1nf capacitor gets played the most. Not because the others don't sound as good, I can always adjust the bass to my liking. I tried the...

http://www.tubeampdoctor.com/en/shop_Mains_transformers_Mains_Transf_for_Mesa_Boogie/Mains_transf_for_Mesa_Boogie_Dual_Rectifier_MK3_MK4_etc_98 This is the one you are looking for for the classic Lonestar. Check description, you will see Lonestar mentioned there. I did a conversion using that...

No, the disc shape pale orange capacitor that you see in the above pictures is the capacitor that replaced the original. The original looks like the other bright orange tube like capacitors that you can see around the disc shaped one. Indeed, the value of the original capacitor was 0.005uf or...

Here it is. The track is recorded in the following way: PRS Custom24 HFS treble and Vintage bass - Lonestar - Suhr Reactive Load - Apogee Duet - Logic Pro with Torpedo Wall of Sound plugin. The plugin is an impulse loader. I loaded a Mesa 4x12 from Ownhammer...

Hi, I will post an audio recording with both the Lonestar Classic and the Special. I modded the Special too for the same reason, too much bass on the drive channel. I know what you mean when you say thick distortion and I believe this mod actually improves the "thick part" of the drive channel...

I thought I should document this for anyone who would like to modify the Lonestar Classic head or combo to a more manageable size and weight. Found these guys at TTC...

Pictures The original capacitor was of the orange tube like type that you can see in the pictures. The new capacitor is ceramic.

Just realized that the flabby/muddy bass issue with the Lonestar Classic is already addressed in a previous post entitled "Flabby/Muddy Bass on the Lonestar? Want to change it?" The link http://forum.grailtone.com/viewtopic.php?f=4&t=27487 I apologize that I "attacked" this issue again...

Hello, Sorry about the length of this topic but I think it's worth reading it. Here goes: My Lonestar Classic - short head, beautiful cleans but unfortunately I was never able to bind with the drive channel. It was simply not possible to reduce the bass as much as I felt it would have been...

I did, no reply yet. Maybe I will just give them a call.

Looking forward to see some pics of the finished project. In the mean time I'll look for an Express cabinet, I want to solve this riddle...

Hi, I would very much like to convert my Lonestar full size combo into a short head or short combo and I am interested to find out if the chassis can fit into an Express 5:25 cabinet, head or combo. I have the dimensions pdf provided by Mesa...

Hi, I need to convert a Lonestar Classic combo to head format and I suspect the Express 5:25 short head shell will fit the Lonestar Chassis chassis, at least after what I saw in the dimensions pdf that Mesa provides to the public. http://www.mesaboogie.com/media/Files/weights-and-dimensions.pdf...

I would like to buy a Dual Rectifier Rackmount version amp. Doesn't have to be for european voltage. Please contact me if you have one available for sale. Thanks, Adrian Got one, thanks!
