VTPH-2 Vacuum Tube Phono Preamplifier Owners Manual
12
ohm RCA load plugs are supplied
with the unit for optional use. Ad-
ditional user specified loading plugs
can also be purchased with the unit.
The moving magnet inputs are fac-
tory loaded at 47,000 (47k) ohms,
100pF. (standard loading for moving
magnet cartridges)
Power Line Polarity
Set the power line polarity switch to
the “A” position. With the volume
control at its lowest position, place
the line stage input selector in the
position to select the VTPH-2 phono
preamplifier.
The moving coil inputs can be
loaded to a particular cartridge speci-
fication by externally connecting the
appropriate resistors using the “MC
LOAD” RCA connectors on the back
of the unit, or they can be internally
soldered at the MC INPUTS circuit
board (this should only be done by a
competent technician).
The moving coil inputs have no load
resistors installed unless specified
by the customer when the unit is
ordered from Herron Audio.
We highly recommend trying the
VTPH-2 in the no load configura-
tion as the unit is supplied for many
moving coil cartridges. 47,000 (47k)
Cartridge Loading
Moving coil loading RCA resistor plugs can be inserted into the back of the
VTPH-2 at the "MC Load" connectors to properly load specific moving coil
cartridges. Check with your cartridge manufacturer for recommended loading.
