Well, now that I have some free time to kill, I thought I'd get the ball rolling on my plans to convert my Mark III combo into a head and Thiele mini stack. I'm min the planning stages as of now. I modeled the Thiele on my computer so I can have exact measurements. Its a hybrid design that...

As you know, I love my Mark III blue stripe to death, and have spent a lot of time tinkering with it. It has some great tones, great versatility, and a great history. Not to mention an automatic membership here in the vintage Marks forum :mrgreen: . After three years or so of...

Just wondering, as it's not on the supported amps list, but I'm assuming that it'll work with the cable for a 3ch Recto, since it's all analog anyway. My friend wants to buy one, but only if he can find a MIDI switching interface. After hearing so much good feedback on the Boogie Board about it...

Hi everyone. I don't normally post in the modern era forums, but I'm here to help out a friend. He might be interested in buying an '05 3ch Dual Rec, and wants to know what a good offer would be. The seller wants $1250. Is that reasonable, or is it a bit high? I told him to offer $1100 and see...

Many of us just can't seem to get the tone in our heads with these amps. Be it a Mark II of any type, or a Mark III, the sweet spot is hard to find. Mesa has made it easier on newer amps such as the IV and V, and other series amps, but the II and III are by far the hardest. The truth is that...

After almost a year of tweaking my Blue Stripe, and being dissatisfied with it's fizzly, thin tone, I FOUND IT. :D :D :D I am so confident that this is the best tone I've ever gotten out of the Mark III, I say it even gives IIC+ owners a run for their money. It is aptly named "The Cream," on...

Well, it's about time we had a legible schematic for this amp. I'm aware that the only one available up to this point in time was both illegible and inaccurate. I am happy to say that this fixes both of these problems! It is completely accurate, and readable. This is for a Blue Stripe MIII, but...

I've been finding the EVM in my Mark III to be a bit too harsh, so I want to swap it out for a Black Shadow. Either MC-90 or MS-12 is acceptable. I'll probably throw the EVM in a thiele, so no trades please. I'd prefer a local pickup, so if you live in eastern PA, or West NJ, or somewhere around...

Well, being the amp perv that I am, I try to find the insides of every amp I take an interest in. Also, it helps me better understand its functionality if I see the actual schematic. Has anybody here actually taken pictures of the ED chassis/PCB? What about a schematic? Anybody know where one...

I need some advice/guidance/information form the NOS tube experts on this forum. I've recently been considering replacing what seem to be the stock 12AX7's in my Mark III. Any Idea who made these back in '88 for Mesa? Was it still Sylvania at the time? I also have two other types that were...

Just out of curiosity if anyone was wondering. I understand that the majority of the components sourced to build a Mesa are found locally in Petaluma, as far as the Chassis Fabrication, and PCB etching, and Capacitors and Resistors are also made somewhere in the US. The transformers on Mesa's...

Hi BoogieBoarder's! I've been reading this forum for a while, and I finally joined after buying a MKIII Blue Stripe DRG. Here's some POS cell phone pics that I took last night of it, if you've seen them before, it's probably from MLP, I'm also a member there. So far I love the amp, got some...
