Searched the forum and not seeing a specific topic on servicing amps. My question is, if I sent a mark iii combo to Mesa Boogie to get looked over and serviced, what would I be expecting to pay? Thanks for any info you must have.

I thought i saw a thread around here somewhere about this but cant for the life of me find it or maybe it was just mentioned in a thread. Anyway, as some of you know, in order to get the "bro0tals" out of a mark III, the clean channel is compromised and the volume knob on the gutiar must be...

well sort of. I got some NOS preamp tubes in and was testing them out in various slots. Knowing I had to pull the 2 6L6 tubes out of their sockets in order to reach in there to get to the pres out, I did so. Anyway, after changing a preamp tube I turned the amp back around and turned it back on...

that I bought off ebay. It had no logos or anything on it, I just compared it with other pics that i found of them. Heres what i got. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110595904946&ssPageName=STRK:MEWNX:IT I slapped it in V2 and cranked it for a bit. My first response in...

I recently got some NOS preamp tubes in today and 2 of them sounded like the ocean was about to crash through my speakers. This only happened when I wasnt playing anything. THey sounded great while playing. Kinda weird. Is this an indicator that something is wrong with the tube? I mean...

Heres one thing I noticed and what could be a remedy. The fan in my III blows directly on the tubes but not all of them equally. I used to own a Mesa 2:90 power amp and the fan was put in reverse so it sucks the heat and blows it away from the amp. Has anyone reversed the fan in thier Mark and...

I know Ive seen this asked a few times an di think I did at one time a while back but never got a difinative answer on. Now, I will refer to a Mark III since that is what I own. I know it has fixed bias. I dont really know what goes on with power tubes and what their "ranges" need to be for...

I changed out the stock Mesa tubes in V1 and V3 of my Mark III blue stripe and the tone change I noticed was immediate. While the stock tubes made it sound great, the amp sounded real bright no matter what way I eq'd it. When I put the RFTs in I didnt realize that the knobs I normally have...

Not familiar with this one but I thought i read on here that these were only blue stripes. If not then I think this would be rare huh? Not mine by the way. http://philadelphia.craigslist.org/msg/1842816639.html

and they turned my mark III into a fire breathing dragon! I cannot believe the difference they made compared to the mesa tubes that were in it. I slapped them in V1 and V3 and the cleans seems more clear and full but not as chimey as before. Really liquid like. THe lead channel, oh the lead...

I havent seen a thread dedicated to just tubes and how they affect the tone on the mark series amps. Ive seen several thread that mention what people use but not one that has all the info in one place. Im thinking this would help any newcomers to the mark series (like myself) with ideas of what...

I have a line on a Mark III long head that has a full power and 1/2 power switch on the front, but on the back it says simul-class. I thought these were different and the full power/half power meant 100/60 watt but simul-class would mean 75/15 watt or 85/15 watt if its a green stripe right? Can...

Whos the collector that will soon have a "crunch berries" in thier possession only to put it in a glass case never to be seen by the public eye? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230465972489&ssPageName=STRK:MEWAX:IT

Why is it that people that own the mark series amps dont post the full serial number and get in a huff when they see others post it? Is there some kind of conspiracy going on with serial numbers or something? Please enlighten me.

I have a blue stripe mark III and it seems to have a reverb problem. Whenever I turn the knob up past zero I get this sound like Im trying to tune into some old transistor radio. I normally dont use reverb anyway but decided to one day and this is what happened. I tried replacing the tube in V4...

Just plugged in my mark III awhile ago and I started hearing static while on the clean channel. It didnt do it the whole time and there was no volume loss. Could be a tube going bad?

Ive read a bit about the kt-77 being a direct replacement for the el34 but also it said that the bias needs to be adjusted. So, if I wanted to try out some kt77s, would I have to have a bias mod done or would it be fine the way it is? Anyone ever tried kt77 in thier mark series and got better...

I know I havent done any deals here on this forum but I have done many deals on the dean guitars forum which all went perfect and have 100% feedback on ebay under the name sickmadman. I have a mint condition Bogner Fish reissue #23. Very low number and by what ive been told, Bogner is only...

Is it possible to swap out EL34s for KT88s on a mark III? I have heard that some amps it is possible but that the plate voltage needs to be higher on a KT88 or something. Anyone elaborate on this?

Well after much debate over which mark series to get, I ve decided on the mark III. I have to say that this amp has a VERY aggressive tone. My god is it thick and saturated. Only thing is, I've discovered that the clean (R1) is pretty much unusable when you have the lead channel dimed. Is there...
