The FRENZEL Stereo SE6V6 Stereo Power Amp was designed for the tube purist to be
used as a musical instrument power amp or as a home stereo power amp. It uses an all
tube circuitry including a tube rectifier. Two 12AX7/ECC83 tubes are used as preamp
buffer drivers. The output is a Class A single-ended design with cathode bias which
allows the use of many of the octal base output tubes including the 6V6, 6L6, 5881,
6550 and EL34. It will give crystal clear tones and will faithfully reproduce what you put
into it.

FEATURES:
Input Jacks isolated from chassis for low noise, eddy currents, and hum.
Laser Etched Faceplate
Classic Chicken Head Knobs, Toggle Switches and Jewel Pilot Light
DC on filaments for low 60 hz hum.
Star ground system to reduce induced current chassis noise.
Input Level Controls for each channel
Classic Type 5F6A Style Presence control.
Unique NNFB "Edge" switch on the PRESENCE control that transforms the power amp section into a No-
Negative-Feedback style amp for more open, less compressed tones.
Post output transformer LINE OUT with LINE OUT LEVEL control for driving a higher power amp, or for
using this amp as a tube preamp/overdrive or recording, Auto switching internal load if speaker is not
connected to give you loaded output distortion.
IEC detachable plug-in three prong grounded power cord.
STANDBY switch to turn off the plate voltage during warm-up.
Rock solid point-to-point hand wiring using only the best of parts...low noise tubular polypropylenes caps,
metal film resistors, ceramic sockets, switchcraft jacks...etc.
Tube compliment: The amp comes with 2 - 12AX7, 2 6V6, 1 - 5U4, but you can substitute 12AT7's or
12AU7's in the preamp/driver for different tones and overdrive sounds. You can also substitute 6L6,
5881's, KT66's, KT88's, 6550's, or EL34's in the output stage for different sounds.

LINE OUT LEVEL – Controls the output level of the Line Out jack on the rear panel of the amp.
LEVEL- Controls the amount of signal sent to the power amp from the driving preamp. Sets the output
level of the amp. Start with this control all the way down. Make sure the preamplifier is connected and
turned on and it’s output level turned up. Bring the amplifier volume upto the desired loudness. You will
need to experiment to get the correct volume balance between the preamplifier output and the amplifier
output level. Ideally the amplifier LEVEL should be turned up at least one half with the knob indicator
lines running vertical.
PRESENCE – boosts the high frequency range and gives the amp more bright punch. Set at ½ for initial
setting. (Please note that a slight scratchy noise is normal as the Presnece control is adjusted. This is
caused by the DC cathode current running through the contacts. It only occurs when the control is
adjusted and does not affect the operation of the amp.)
EDGE PULL SWITCH (part of Presence control) – when pulled out turns off the negative feedback in the
amp which produces a boost in the volume and a more dynamic less compressed tone.
POWER SWITCH – turns power ON to filaments of tubes. Pilot lamp will light up when switch is turned to
ON (up) position.
STANDBY SWITCH – turns ON high voltage to tubes. Allow tubes to warm up 3- 5 minutes before turning
to ON (up) position. This protects tubes and lengthens tube life. Turn to OFF position(down) when amp
temporarily not in use.
PILOT LAMP – lights up when Power switch is turned on.

Channel 1 and Channel 2 Controls
IMPEDANCE SELECTOR – selects the output impedance for the speaker to 4 – 8 -16 ohms. Set the switch
to match the impedance of the speaker.
SPEAKER JACK – a 1/4" unbalanced jack connects output of amp to speaker.
LINE OUT JACK - is a post output transformer 1/4" unbalanced jack LINE OUT jack. Works with LINE
OUT LEVEL control on Front Panel. Can be used for driving another amp, mixer , recorder etc. It can be
used without a speaker plugged into the amp. There is an internal load connected by a switch on the
speaker jack if a speaker is not plugged in. This internal load simulates the speaker and will give you
loaded clean and output distortion tones.
CHANNEL INPUT JACK a 1/4" unbalanced jack is used to connect the signal to each of the amplifiers
channels. Plug output of preamp into this jack.
Power Section
FUSE - protects the power supply. Use a 3 amp SLO-BLO type fuse.
POWER CORD – a detachable power cord connects power to the amp. Make sure that the cord is fully
seated in the connector. The power cord is a three prong grounded cord. Always plug into a grounded
outlet to prevent electrical shock. The line voltage is shown over the power cord bushing. Be sure that
the voltage matches your line voltage.
