Hey Bro!

mine's actually 15434, but we're still pretty close. i've got a bare-bones model: 60 watts, no eq. the transformer seems to be a smaller 60-watt model. Let me know what you find out about your transformer. i think the identifying numbers are on the underside of the xformer on the left. (as you face the back of the amp) i'll try to take a photo of mine & post it for comments.

How's that thing sound?

I just purchased a loaded no-stripe (MB) Mk III head #15464 (20 numbers later than boogiemon [hello brother!]), and my tech told me it was the "higher voltage" transformer. Where is that stamped transformer ID located? Is it somewhere it can be seen without disassembling anything? It'd be cool to know.

Mark III Long Chassis SN/24428

I have know idea what stripe or dot because I have yet to see it. I'm buying it from an out of state guitar center. The only thing I know is the guy told me it has a Red (R) on the back? He thinks its initials but hes not sure. I don't even know if this thing is a Simul-Class.

I spoke with Mike Bendinelli He told me it might be a green stripe with a number that high. That really sucks for me because I want the IIC+ tone and response just like all the rest that buy a Mark amp looking for the Master Of Puppets, And Justice For All, Black album tone. I have looked for that tone going on 10 years now. This will be my first Boogie;)

With a number that high, it's likely a green if simul-class and a blue if 60/100. 8)

Yep, that would be a rather late Blue, overlapping with the Greens and possibly with the early Mark IV.
Is it a Simul-Class? 60/100?

Yeah sure is and it has an EQ. I'm going have to take it apart and see if i can find the date anywhere :)

There should be a date written in Magic Marker on the bottom of the chassis. No need to remove the chassis from the cabinet.

My Red stripe MKIII is serial#21XXX and dated 10/87, DRG. When I became it's proud owner in 2000 it was in it's original EV loaded Black tolex 1X12 combo cab. Around 2003 I scored a Imbuya/wicker 1X12 cab for it. I recently contacted GTS about converting it to a head and he crafted me an awesome head shell covered in Red snake skin tolex. I'll post up some pictures when I figure out how to on this site.

Nobody else care what serial numbers/years each stripe came out in seems to me with the exception of early mark 1,s the other marks are pretty well documented.


Hi bartchamdoh!
Actually, the Marks started to be well documented after Mesa moved from Lagunitas to Petaluma.

The Mark II-A series is as much a mess as the Mark I. I have a Mark II from 2/80 with no serial number.

Boogiebabies' proved that last s/n on the IIC+ (except for the odd 15,000) was around 14,400.

In the same way, I want to share the observations I gathered about the last serial numbers on the transition among Boogies chapters:

1) The last Mark I that I have seen are:
- 7/78 with s/n A2213
- 8/78 with s/n A2148
- 8/23/78 with s/n A2179
- 9/78 with s/n A2259

2A) The last Mark II-A that I have seen is:
- 8/14/80 with s/n 5574
- 9/10/80 with s/n 5022

2B) The last Mark II-B (8/80 to 5/83) that I have seen are:
- 5/83 with s/n 10654
- ?/83 with s/n 10881

2C) The last II-C (5/83 to 2/84) that I have seen is:
- 2/84 with s/n 12376

2D) According to Boogiebabies, the last Mark IIC+ (2/84 to 4/85) he saw was s/n 14,36x (and there is an odd s/n 15,000, according to Ian Dickey). The first original Mark IIC+ that I have seen is s/n 12,467 from 3/84.

3) Now, regarding the Mark III:

- black stripe (3/85 to 1/86): 15001 to 16715
- purple stripe (1/86 to 12/86): 16657 to 19059
- red stripe (12/86 to 1/88): 19100 to 21863
- blue stripe ('88 to '89): 21825 to 24933
- green stripe ('89 to '98): 24940 to 28386

Blue Stripes in 60 W or 60/100 W power amps extend into green stripe territory. Amps in head configuration are sometimes out of their own stripe range as well. Anyway, keep those odd s/n and manufacturing date coming.

4) Finally, for the Mark IV:

- version A ('90~'93)
- no A/no B or early B (1/93 to 12/93): s/n 5,9xx to 6,7xx approx.
- version B ('93~'08)

Regards

Not to side track the thread but we've seen/ documented at least five C+'s earlier than 12467.
A couple were even in the 122xx and 123xx range!
