The great return of the MKIIA :)

Post by mark2boogie » Sun Sep 30, 2018 3:59 pm

Most of you Guys have MKIIB, MKIIC, MKIIC+, MKIII et consorts...

The MKIIA is less seen, so I decided to repost something about that model, with my pics... 8) :roll:

I did a heavy job to make that amp working nearly flawlessly, I mean : no adverse noise (hum, pops, scratches, Larsen) at any setting, a great deep balanced reverb tone, a progressive volume and master controls, a usable FX loop, a complete FSW, a "Santana" speaker...

For some time, I added an EVM12L Thiele cab, that I finally sold for weight reasons :oops:

Image

And even an (aftermarked vintage) hardwood cab, that I also sold for weight reasons and fear of damaging it :oops:

Put in a FlyCase "lite" (7kg) :

I built a "complete" footswitch :

I also built an FX loop adapter :

What I can't improve is my age and my backbone... My MKIIA in working order in its flycase is an anvil to carry : it's his only drawback !

A+!

You have done a great job making the wonderful MKIIA even better. I played mine on Saturday. Great growl on lead, chime on clean. They should reissue one with your improvements and an effects loop.

Thanks b100g13mk2B !

Yes, the MKIIA is a great amp, which offers improvement possibilities... Except for the weight !

I retrieved the fichier (dated 07/2011) which listed most of the modifications I have made to my MKIIA :

Sorry for the small pictures - if you want more details, feel free to ask.

Note : common sense lets you guess that you need enough knowledge, skills and tooling about tube guitar amp and electronics if you want to go that way, or at least you have a good friend that have all that to help you do the job... Or do it for you ! I mean : it's not for beginners, OK ? :wink:
