This is an updated version of the C10 called the C10+. Built on a 10" X 6" Hammond Steel chassis with a tube cage for a nice portable and durable head.  The amp has a modified power supply with a beefy power transformer, large choke with extra filtering. A 15 watt single ended output transformer pushes a single EL34 output tube. It can also run a verity of different octal output tubes (6L6GC, KT66, etc.).  Right now it's running a 5U4 rectifier tube and a 12AX7 preamp tube, both of these can be substituted for different tones also. Front panel features are a fat switch, volume and tone controls, and a foot switch jack label SOUL that bypasses the negative feedback for a beautiful creamy lead boost. On the rear panel there is two speaker jacks, a four p ...

I have been wanting to try an amp with a EF86 preamp. I studied the Vox and Matchless circuits out there and came up with and 18 watt two channel amp. The first channel has volume, bass and treble controls with a beautiful glassy clean tone with single coils. The second channel (EF86) have volume and a six position tone switch that excels with humbuckers for semi dirty and full out overdrive tones. The power amp has a cut control and a master volume on a pull switch, so with it pushed in the MV is out of the circuit. This amp is all about driving those cathode biased EL84 into smooth overdrive, and singing feedback is possible at reasonable levels. A little bonus, when this amp was done and sitting in the living room I got to teach my twelve year old son what feedback and sustain was.

Here is an old Marlboro solid state amp I rebuilt into a C38. It is the stage amp used at the local blues jam at the Rusty Nail in Ardmore, Pa.with The Blues Mercenaries. http://www.bluesmercenaries.com/index.html   It's has been in for various repairs over the years, but finally died after it took a face first fall off the stage. I reused the chassis, cabinet and the speakers. The guts are all new with some nice beefy Hammond transformers, custom circuit card construction with Mallory caps and a mix of carbon comp, carbon film and metal oxide (power) resistors. It has some power supply tweaks to add a bit of compression and sag for a nice bluesy feel. The bright and normal inputs are internally jumpered, so the player can plug in to either channel and dial in the right amount high and low en ...
