TWIN
HEAD MK II
The
Twin Head MK II is ASL's flagship remote
controlled tube preamplifier with a headphone
output. 2A3 triode tubes, OTL/Transformer outputs
and all tube external power supply.
Custom
modifications can also be developed for this unit
based on your particular sonic needs and desires
to match any one of our modified ASL amplifiers or
any unit you may currently own. Please feel free
to contact us to discuss the possibilities.
A
fully, custom modified version of the preamplifier
will soon be available, January 2005, as we are
currently in the process of developing this
upgrade.

Audio Reference Version
A
new Platinum series modification has been developed for this unit.
We have taken this unit to the extreme to
the point of holding it's own when driving
our EXtreme Hurricane or Monsoon amplifiers
as well as any amplifier you may choose to
pair it up with. The Platinum OTL32
utilizes a simply preamp gain circuit and is
an excellent choice for those looking for an
open, airy presentation at a very affordable
price.

Reference
Series Details
-
One brand new ASL MG-Head DT/OTL 32 preamp
-
All signal path Coupling capacitors
replaced with SoniCap Platinum Teflon Reference
Grade capacitors (both preamp and
headphone circuitry)
-
Electrolytic capacitors in the
headphone circuit are replaced with higher
quality pieces that offer a lower ESR as well as
SoniCap Gen 1 film capacitors. (when required)
-
Critical resistors replaced with
Dale/Vishay 1
watt, 1% metal film resistors. These will
replace the inexpensive 1/2 watt pieces in the
preamp now. Going with a larger physical size
and wattage provides a quieter presentation for
better low level resolution and transparency.
-
Signal tube cathode resistors replaced with high
quality Dale Vishay units.
-
Elna Cerafine capacitors used at signal tube
cathode bypass.
-
Electrolytic power supply capacitors
replaced with high quality pieces with
lower ESR (resistance).
-
All internal signal path wiring
replaced with our 22 awg copper wiring
or 22 awg silver plated copper.
-
All RCA input and output jacks
replaced with much better quality gold plated
pieces. (optional-call for pricing)
-
Where ever possible, all circuit board
copper tracing will be eliminated with direct,
point-to-point wiring.
-
Ground wiring layout is redone to optimize a
low background noise and lower noisefloor.
-
One pair of Bybee Quantum Purifiers
installed at the signal input or signal output.
-
Sonically,
the OTL 32 offers a refined, open presentation
with an extended, airy upper end.
Price: $1,525 brand new units. (includes
shipping)
