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.
