If you can get one the Eminence MOD 12 is a great speaker for the small combo cab. If you want something lighter weight, Jensen Neo Tornado, the 100 watt version.

The diodes appear to be OK. Next things to check would be the filter caps in the power supply for shorts as already mentioned. In order to check the power transformer you have to disconnect any secondary wires from the circuit, tape them so that they cannot short against anything, put in a new fuse ...
Fwiw a lot of folks out there are misinformed about what Mark series amps can be modified to a C+ and which can't (and why). From what I have read the IICs can be upgraded to a IIC+, which is what MB have offered as a factory upgrade. I also know that the first Mark IIIs (no stripe/dot/black stripe...

I will review the pedal in the context of the manufacturer's description and the way I tested it (standalone before clean amp, push a driven amp and clean boost after overdrive). This is how Mesa Engineering describes the pedal: The FLUX-DRIVE™ is the overdrive pedal for those who want more of all t...
Can't be done. Most notably because the IIC(+) and Mk-III have different pre-amp circuit boards. Never mind the PT etc.... I guess you meant by "can't be done" "can't be done exactly", and if so, I agree. Different circuit boards have different stray capacitances. I also agree that power transforme...
The smaller electrolytics are mostly in parallel to the cathode resistors on the preamp stages. They increase gain. Unless they are faulty you will probably not notice much of a difference between one electrolytic and another.
Here is what I did to my purple stripe: 1. Change C30 from 0.002uf to 0.001uf. 2. Change C516 from 0.01uf to 0.0047uf (this cap is in the feedback circuit in the output section) Check whether the output of the lead circuit has the 220k II 250pf to 100k II 500pf voltage divider. My amp had it but the...
One big myth is that the Blue Stripe is the same as the Red stripe minus the C30 mod. There are lots of component values that were changed between them. The Green and Blue stripes also have a different resistor alongside the C27 capacitor that is supposed to have as much if not more of an effect th...

Given that the Mark amps are Fender based they are an excellent pedal platform. One of my favorite drives with them or any other clean amp is the Barber Direct Drive (any variant of it).

I used those when I retubed my Mk III a few weeks ago. Too early to comment on the reliability but no problems so far.GJgo wrote:When I asked Mike B. for my 105 PT he recommended the TAD 6L6GC-STR as one that can take the voltage. If you read up on it it's loosely designed after the old 415.
Jon, Many thanks for sharing! The lead circuit is quite similar to my purple stripe 60 Watt, except that - the resistor in parallel with the lead drive pot is 470k instead of 150k, which would provide for a bit more bass at higher settings. I think the 150k is actually beneficial as it tames bass be...
