Where can I find a schematic of my Mark III blue stripe?

Thanks for the replys. I'm not really skilled to do any of those things. Just wanted to know what the problem could be before I bring the head in for service. Now that I think of it the Reverb is not even working (never use it). When I try raise the Reverb knob it just distorts in a bad way...

My Mark III blue stripe started making a low frequency hum even with the volume set at zero on the clean channel. Other than that it works perfectly. Could this mean that I have to change the caps? If this is the case. Where do I find a schematic with the values?

Is it normal that when using the clean channel of my MKIII there is some lead channel sound bleeding through?

I wish i did. I use the footswitch only to change channel (clean/lead). No one wants to tell me something like "It's nothing to worry about. The tech will fix it easily.... "?

The thing is it worked perfectly till that day. Anyway I will take it to a doctor to cure it.

The other day I was playing my MKIII and was passing through the various eq options (auto, in, out). So at one point I placed the switch on Eq Auto and the sound went from lead to clean. Now when I play the lead channel on the EQ IN and OUT it is distorted when I go to AUTO it becomes clean...

I read the wood is baltic brich. tried to find some but I can't. What would be a good alternative? I immagine the type of wood is important.

Hello everyone, I have to ask a thing a bit out of topic but preferred not to start another thread. I have a 4x12 Half-back cab and would like to have a panel to close the top. Did Mesa Boogie ever produce them? If yes do they still do them? And if so, how can I get one to arrive here to...

Thanks. That was what I was looking for.

I have the manual of my amp. thank you anyway. I think it is a sort of user manual for extencion cabinets. :?

Hi, I am searching for a page I once saw, I think from mesaboogie.com. It showed every possible combination of amp/cabs in order to match impedance. Does anybody know what I'm talking about? Anyway I want to run my mark III head through two half-back cabs, a 2x12 and a 4x12. :) Can I do it...

My english is a bit weak. what do you mean?

Thanks for the replies. A 4x12 halfback Cel/EV setup is the holy grail tone cab ! In good shape $500 (USD) + the 20%. this is far less than what the guy is asking for........ About replacing the speaker, I think that finding only the EV (no cab) would be very difficult for me. There are...

Hi. How much should I pay for a NOS (it was never used!!!) Mesa/Boogie 4x12 Half-back Cel/EV? I live in europe so add 20% (for US people). I even found a 4x12 Half-back loaded only with EVs, but the guy doesn't want to sell it anymore... I have a 2x12 with Celestion C-90 and 50W eminence and...

So speakers make the difference. Will the new ElectroVoice reissues work fine?

I've traded my straight Jcm "Vintage" Marshall 4x12 cabinet for a Mesa/boogie Half-back Cel/Vntg 2x12. In the bottom part there should be a Eminence speaker, right? I tried to open the bottom to see what speaker actually there is and I found out that it's full of a white acustic isolation...

I was very into the 2x12 exchange for two reasons: 1 seems to have good bass, enough to aviod getting a 4x12. For recording and rehersal purpouses it seems perfect. 2 I have a rackmount version of mark III so it would fit perfect on top. But now Celestion and eminence seem to be the worst...

Hi, I'm going to get a mesa cabinet but need advise to do the right choice: 1)trade Mesa 2x12 half-back Cel/Vntg with my Marshall 1960bv 2)trade (plus 100$) Mesa 4x12 half-back top V30, bottom Black Shadow with my Marshall 1960bv 3)sell a kidney and buy Mesa 4x12 half-back top Black Shadow...

Hi, my name is Lorenzo. I have recently bought a Mesa/boogie Mark III blue stripe rackmount version. The guy who sold it to me changed tubes and had it serviced, by one of the TWO guys who know how to fix guitar amps in my city... I'm not very into Metallica nor Dream Theater metal, I used...
