the opto series evolution and history - never bring a knife to a gun fight
well drip is glad you asked , a bit of a story , but here it is :
10 years ago drip was first in the world to release the first viable and fully operational pcb of the classic (trademarked) "LA2A" compressor , to the diy community .
awkward , but viable . and it was 100% the original circuit of the la2a.
the first drip opto pcb was the beginning of drip , it was released in the prodigy pro forums (now group diy) aprox 10 years or more ago . it was the wild west back then , and the staus quo was the norm.
the forum life was torturous for drip , a mob mentality never cultivates a good idea or artistry.
it was a great place to start , and drip rolled with it. but damn , haters just wanted us to die.
dripelectronics.com was set up after the initial success of the opto 1 so drip could escape the retarded behavior of the forum trolls .
from then on , drip was free to be creative and have a direct connection to some amazing
folks and at times some not so amazing .
the opto 1 - circa 2004-2005 release
the opto one pcb was drips first released pcb . (UA trademark was not yet established at the time of development)
you will notice from the design that drip was still struggling with the symmetry issue .
however , the tube amplifier and control amplifier has what was to become the beginning of a style.
hand drawn with a mouse in the most basic of design programs back then 'protel'
the goal was to create an elegant style that looked beautiful and functional . in beauty one often is attracted to symmetry , in symmetry one often achieves balance in audio design , balance is everything .
the design reflects the beginning concept of using curves in the design ,
you wonder why pcb designs of tube equipment sound like hell . well , its the structure of the wiring that does this on the pcb ,what we wanted achieve was to be more organic in the layout .
point to point wiring is very organic ,
smooth , curved , 3 dimensional and if executed well , beautiful , and can sound perfect.
the emulation of this on a 2 dimensional surface was the original drip public enemy #1.
bad messy designs reflect the heart or ignorance of the designer and reflect the integrity of the circuit.
re-creating the 'la2a' is equivalent of making a copy of the mona lisa ,
you better damn well be sure your friken heart is in it , and you better damn well give it some respect.
in the case of the opto one ,
the heater issue was not resolved yet , so the heater filaments of the tubes had to be hand wired and twisted .
amateur night at the rodeo .
there were many superstitions that developed during this design of the opto one.
the power ground , reduction ground and signal ground were all separated , meaning a different ground point for each stage . as in the original design , we followed that architecture .
good move , it helped in function and is used to this date with the opto series ,
the metering section of the opto one fell apart , just needed to finish and opted to use orthogonal 'gross' traces and
basically just 'threw up' onto the pcb with this travesty of absolute loss of balance .
'worked though' , is not an excuse for this sacrilege .
the main circuit design is beautiful , amateur , but one can see the hope in a foundation of what was to become the future for drip,
more to come ,
next the opto 2
