Bk Butler Tube Driver For Mac
I've obtained two of thése BK Butler Tube Motorists. One is definitely an older (80s?) edition with a black framework and bright-yeIlow lettering and ranges, and which demands powering by an exterior 12 VAC resource.
I composed to Butler's business and a specialist there validated it as a real Butler your pedal, as opposed to the Chandler 'reproductions.' The various other can be a newly made re-issue with prejudice button and buiIt-in transformer, ás backed by Eric Johnson. For years, I thought the older a single I had was very different and low quality to the new stuff. Then I bought the new re-issue version and got an A-B assessment. They're also both simply as good and the range of sounds available from each are pretty significantly similar, except that the knobs have to be set very differently on each your pedal to achieve the exact same sounds. I've got a 12au7 in the outdated one and a share tube in the brand-new a single (no idea what it is).
To my ears, to get the comparative of an Eric Johnson setting (treble button all the method down) on the new edition, you have got to set the older your pedal at treble 4, middle of the 4, striper 5. Therefore, establishing the commute button at various ranges impacts the shade controls so that they react in a different way on each your pedal. It'beds barely noticeable, but the old pedal tends to become somewhat more soaked on the mids and also has even more hiss/hum, whiIe the newer one is slightly more transparent and quieter. Aside from that, dynamic and tone responses from both are usually nearly similar.
I recently picked up a 5 Knob, yellow and black, B.K. Butler tube driver. It's the version that says 'Real Tube' and 'Tube Works' on the front. Shown above (left to right) - The 1985 BK Butler Tube Driver, the revised 1986-87 BK Butler Tube Driver, the unauthorized 1988 knockoff made by Chandler after Butler parted ways with them, the 1990s Tube Works 911 Tube Driver, and a B.K. Butler reissue of the 911 Tube Driver from 2006.
Becoming pedantic about sound issues, I would choose the newer one, except that it's really large, way too big for my regular pedal plank. My mission is definitely to someday restore the newer five-knob edition into a smaller sized package. From what I know, it's not really one of the much easier pedal projects to perform. Therefore would anyone including to join me in my quest? Anyone want a peek at the innárds of these pedaIs in purchase to generate some schematics? Or are usually they already posted somewhere on this site?
I searched but couldn't find anything right here. Posts: 21 Joined: 22 Might 2014, 23:00 Offers thanked: occasions Have thanks a lot: time. It was enjoyment to build. I use it every Weekend at cathedral, mainly in front side of a cataIinbread DLS but occasionally by itself.
It seems every little bit a tube driver, in reality it noises quite a bit much better than my aged 4 knob one. It's i9000 based mostly on the rackmount individual tube edition (with the dark board), but only freely. It's i9000 driven by a 12vair conditioners wall-wart.
There is definitely a jfet out front side, a 2n5457 I believe, traveling a get pot, followed by thé grid stopper ón the very first triode. There are usually no opamps. The jfet supply bypass cap can be in series with a trimpót with a fóotswitch across the trimpót. I arranged the trimpot in house for 'reduced get' setting and the footswitch shorts the container for full increase and high move.

It works quite well and can be modified to become simply a get boost or to get louder and very much gainier. I can't remember exactly which component values I used but there is a cathode pot mounted on the back again face of the pedal, fixed up similarly to the Butler 'bias' pot on the newest variations. There is clearly a 'lovely place' on the tube prejudice knob where it sounds right; some other positions don't really function for me. I would end up being tempted to bring the internal off-boost supply cut to the outside as it could create the gain boost even more helpful. Of program, then you'd finish up wanting various EQ and volume configurations for each ánd it would get out of control.

Then again- switching from Gilmour to EJ mode on the fly would become gnarly. I should function that out. I put on't believe I have any photos of the completed version but it got a little bit messier as I completed cabling it. The container will be 4' broad and about 5' deep.

I'michael sure it could end up being carried out neater on a Personal computer table but I adore turret structure and I got very a several of the tiny platinum turrets. I used thé PEM stud inserter át work and pressed in hard mounting points for the table so no anchoring screws display from the best of the your pedal. It's i9000 plain aluminum with clear LED pulls, clear Directed slots and vivid glowing blue and natural leds. Changes emerged from BLMS. Allow it also be said- you could build one with á submini tubé in a small chassis and it would be incredible.
The submini tubes I've performed with sounded excellent. I only used a 12atimes7 in this because I needed to end up being capable to swap more quickly. If you wish a 9vdc powered version you can buy a tiny chinese language dc-dc convérter on ebay, energy the tube from a 7806 or chain of diodes and tube plates from the output of thé dc-dc (aróund 36 to 40 volts). I purchased a bunch but haven't yet played around with with them. Jamie Content: 39 Joined: 17 April 2008, 10:46 Has thanked: times Have thanks: situations.

The unit is certainly a tad various likened to the some other schematics I could discover; Bernardduur, strength supply can be voltage doubler, whát's the transformér's supplementary voltage? Not a voltage doubler.
