gts,
your comments are always welcome.

I think I saw one serial number 1228x that Boogiebabies said it was an upgraded C to C+ but surely there has to be some 2/84 original C+ amps out there. Please feel free to copy and edit the post with what you have seen/documented. Mine is just a work in progress.

Thank you and best regards

Interesting to see one of the c+ transformers in the 800,s keep it coming guys.


Actually, the X100/X101 (100 W) and the X62 (60 W) were the export transformers for the Mark series from the Mark I up to the Mark III. With the Mark IV, Mesa discontinued the export transformer.

The difference between the X100 and the X101 is:

- the X100 is the older one and the voltage selection is: 117; 200; 210; 220; 230 and 240. It was used on Mark I, II-A and II-B.
- the X101 export transformer has the following voltage selection: 100; 117; 200; 220; 230 and 240. It was used from Mark II-B up to Mark III.

Now, what country uses (or has used in the past) 210 Volt? Maybe selected for some European/South American countries with lousy electrical grid quality and lower than nominal 220 Volt?

The X62 export transformer has the same voltage selection as the X101.

Regards

I have been revising some numbers. Here you have my last version of ballpark serial number transitions between Mark III stripes:

- 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): 18949 to 21863
- blue stripe (1/88 to 5/89): 21825 to 24933
- green stripe (5/89 to 9/98): 24898 to 28386

Blue Stripes in 60 W and 60/100 W power amps extend into green stripe territory. It seems that all green stripe were Simulclass and fully loaded (same thing Mesa did with the Mark IV). Amps in head configuration are sometimes out of their own stripe range as well.

Please, keep those odd s/n (manufacturing date included, please) coming.

Regards
Daniel

Muito obrigado, Vigo, for the info on your 10/90 Mark IV.

As a separate note, I checked the timeline in the Mesa brochures and I found that they put 1989 as the initial date of Mark IV manufaturing. Yet, that timeline is a little bit inaccurate. It states:

- Mark I: 1972
- Mark II-A: 1980 (instead of 1978)
- Mark II-B: 1982 (instead of 1980)
- Mark II-C: 1983
- Mark III: 1986 (instead of 1985)
- Mark IV: 1989

Regards

For those keeping score at home, I have a Mark III short head with serial# 22671 Blue Stripe. It is Simul Class and has 60/100 W switch, no EQ. Has R script and MB, and a plugged hole marked Reverb on the rear panel next to Presence.

Looks like 11/98 date code.

Never really have been happy with the sound, it is very flat sounding, not live at all. I have tried Mesa tubes and JJs.

First Mark III was a fully loaded head (except A/C plug). Serial number was 15924. She is gone now...nothing ever compared to its performance and tone.

My present Mark III is a blue stripe combo that pales in comparison to my first Mark III. Its serial number is 226??. MB's initials are inside and under power cord. It was built in April of 88.
