So after for what seemed like eternity (2 weeks, 6 days) - I got my C+ back from Mesa!
A little history on the amp and old pictures from roughly a year before I bought it can be found http://www.grailtone.com/forum/viewtopic.php?f=27&t=48517&start=0
Originally a Mark IIB with GEQ/Export Tranny - it was converted to a C+ and Simul-Class added in 1987. Sometime during that period the tranny was replaced.
I had the amp for roughly 6 months, I started having some issues.. I had severe microphonic noise coming from the power tubes, I noticed the thing was running wayyyy too hot, I had my V3 preamp tube go out, and just overall loss of sound quality. So it was time to go to Mesa.
I spoke with Rich, who quoted me the typical $175-250, and got it shipped out... 10 days later I got a call from Mike B., we talked options for the amp and repairs it needed.. my estimate went to $320, followed by another call the next day, with more work needed, taking it to a total of $436.70, $213.70 for parts, $200 for labor, $23 for shipping...
As for what was done to it, here goes...
Replaced filter caps, EQ sliders, upgraded the power tube sockets to porcelain sockets, clean up and rewire of main supply board, clean and services pots and pull jacks, rewired most pull pots on front, replaced 3 resistors, removed excess wiring from export tranny, replaced all power tubes, replaced power cable, added power cable socket, rebiased amp.
So basically.. after I changed out the preamp tubes (with Dougs Tubes preamp cocktail).. I have a brand new amp!
Now for the pictures (check out the old pictures to see how nice it looks after coming back from Mesa)
Tranny
Simul-Class
New sockets and power tubes!
New power cable, socket, refreshed "MB" initials, newly added "+"
Sitting in my awesome GTS shell.
Sitting with baby brother.
Replacement parts list!
I can't tell you guys how stoked I am to have the amp back in this shape, it took me forever to get a IIC+, and though it's not factory, it's my baby!
Sorry for huge post, it's like Christmas for me!
