The sweet deal is this, neither
Scott nor I have any intention of potting these modules (click for pix
and prices). As such, we are "exposing" ourselves to being copied
(and you must know alot of work went into making these right), but we're
not afraid. What we are hoping is that people will do one or more
of the following:
appreciate the benefits of
not potting -
better thermal dissipation =
longer life (the modules will pay for themselves over time)
less heat = less noise and
repairable should they fail.
have the ability to see how
the circuit is implemented - an exact copy of the most desirable version
of the api-2520
some potted 2520 clones have
IC opamps in them -
the SL-2520 is "just"
a 2520, a hybrid of surface mount and standard transistors.
appreciate that as best as possible
did a particularly good job of selecting modern parts that perform as close
as possible to the original. To further match the sonic fingerprint,
Scott then tweaked the circuit as per the original designer's "circuit
handles" to achieve similar results. That is, great pains have been
taken to achieve similar distortion characteristics - higher distortion
than modern opamps but a complementary distortion that is both musical
and part of the essential 2520 characteristics. (we can post this
information once there is officially an SL-2520 home page.
users can think of the SL2520
as "open source" in that it can be tweaked. Of course, this voids
the warranty, but anyone with geek chops who are trying to match a particular
batch of api-2520s - since they are not all the same - can easily do so.
I hope this helps, and thanks
for checking us out.
