Some guys post some wicked builds. This is not one of those and truly is a project amp!
Originally, I was planning on a 2 hole rocket but then RJ had to go and build an octal based version
So I ended up with a 2 hole rocket with the 2xel84s or 2 octals.
This was also my first effort at actually doing something a little different and I can say that it brings a new level of appreciation for those who actually manage to come up with stuff in the first place.
Dana had perked my interest with his capcans and his Express so I decided to use one of these and pair it with distributed filtering for the preamp sections.
Grounds were revised and I also decided to play with the filament wiring and not twist the wires.
Biasing is via a 50ohm resistor in series with a rheostat. I decided to fuse the OT mainly because of the variable bias. A switch selects between the octal or 84s.
I included a bright switch and eventually included a cap to bypass the second stage for some additional gain.
The amp is very quite despite my messing around with it which is a relief!
Overall I am pleased with the result. I still need to actually finish it and get a cab for it but it makes some noise and all that have heard it have been complimentary....
I have include the PDF which is pretty much what I was going from. It is not 100% accurate but it may be of use to someone out there. I have the visio file also if anyine is interested.
The clip is a friend of mine who is far more capable than I with a guitar and had an hour or so with it. . It is all el84s but has a split coil and a humbucker on it. He wasn't too happy with it but it is still far better than I could do.
Hopefully I will get an octal based clip at some point in the future but do not hold your breath....
