    Cool man, it's a fun, easy amp to work on for sure (if you're into that kind of thing, and you alluded to that above).



    Definitely recommend the .1uf bass cap and changing out the treble cap to a silver mica. I am going to change the mid cap to a .015uf at some point to try it out, but I don't think the change will be as profound as the change to the bass cap.

        I pretty much buy all of my amp parts at http://tubedepot.com/ these days - flat rate $4.95 shipping, good stock, and fast service.



        For filter caps, these have been great (and fit well in the blues jr): http://www.tubedepot.com/ftgermany.html - the 100uf 450v is what I used for the first filter cap and the 22uf 500v for the other 3.



        As far as tone and coupling caps, you have a lot of variation and choice here. I use the orange drop 715 series. You can also get the 716 series, or the Xicon or Mallory. I've read online that some people don't like the 715's, but they seem to work fine and sound fine to me. I have found in the amps I've built that the orange drop for the bass and the mallory 150 for the mids gives a little more top end shimmer then using both orange drops... but, admittedly I could be hearing things.



        For the silver-micas, whatever brand tubedepot sells is what I'm using: http://www.tubedepot.com/silvermica.html



        When I build, or if I had to replace a cathode bypass cap, I use the sprague 25uf electrolytic caps.



        Hope that helps!

          Fantastic! Should be all I need for now, I am pretty safe and ready to work. The Navy made me paranoid as hell about electricity since I regularly had to safe the Spy RADARS 75,000 volt caps. Needless to say, every time my butt hole was very tight. But I am going to try this when I get back to San Diego after Christmas in NY. Can't wait to tinker! Thanks again Wagdog you have been a great help. I'll resurrect this thread with updates and pics as I get things done.

            All right man, good luck! Considerably less voltage then what you would find in a 75KV cap, but dangerous nonetheless. In spite of what billm shows in his site about discharging the filter caps - discharge the caps by bleeding them. I use a 20k resistor and a grounded alligator lead and then check each cap with the meter. Takes a few seconds and no surprises that way.

              I might be late to the party here, but having tried both of those speakers in my Blues Jr (which I sadly no longer own), I'd say that the Eminence Legend GB12 is the best speaker for that amp. No additional mods needed for the low end or anything. My Blues Jr. Had the GB12 and some JJ tubes, and that's all that wasn't stock. It had great cleans and even better natural overdrive. Sadly, I had to sell it when I had been out of work for months. Anyway, good luck with your speakers!

                Thanks for the tip! I am still going to do the mods, but having input on speakers for later is always helpful.

                  Not to hijack this thread, but is the new Blues Jr III basically a factor modded Blues Jr? And what speaker in a Blues Jr III would get you closest to a DRRI clean tone?

                    There are some differences in the III. Billm pretty much spells it out here in much detail: http://billmaudio.com/wp/?page_id=709



                    No idea on the speaker. I've owned a DRRI, and obviously still own a blues jr - and they are different amps, so much so that I don't think you're going to get one close to the other. Some people have added octal sockets (something I'm thinking about) for running 6V6's, however the most major of the differences is the completely different pre-amp topology - they are just very different amps.

                      texas heat will also make the amp louder due to its high sensitivity.
