1W x 2 single-ended power amplifier (Headphone amp)
This is one of our top model single-ended power amplifiers. Although it only has 1Wrms, it can drive a pair of speakers with 90db/W efficiency to a reasonable loudness level. It is also a very high quality headphone amplifier, super quiet, super warm and rich sounding, with good body and density. The output transformer uses a NOS UTC 2W wide band transformer 600:8ohm type.
There is a special version of the SE-6AS7G, which employs a HPF (high pass filter) switch to select either full range or high frequencies. Another pair of pre-amp RCA outputs can be added to let this amp perform as a transformer output pre-amplifier. A pre-amp / power amp switch can alternate between speaker output or pre-amp output. This option will cost an additional C$300.Specifications
• No. of inputs: 1 set of RCA inputs
• No. of outputs: 1 set of speaker outputs ( 4-16 ohm) + one 3/4 phone jack (option)

2W x 2 single-ended power amplifier (Headphone amp)
This is one of our best sounding single-ended power amplifiers. Although it only outputs 2Wrms it can nevertheless drive a pair of speakers with 88db/W efficiency to a reasonable loudness level. It is also a very high quality headphone amplifier, with a super quiet, super warm, rich sound. The output transformer employs a NOS UTC 2W wide band transformer.
This is the enhanced version of our small powered 6AS7G amp, which has a bigger power transformer for higher power output capability as well as a more transparent sound quality. This version can be built with a 300Hz (option: any freq) high pass filter with a by-pass switch. This makes it easier to adapt between a normal single amplifier system or a bi-amped configuration. Input level controls give flexibility to best match the tonal balance between the hi-section and lo-section amplifiers in a bi-amped system. A 3 input version is also available. Specifications
• No. of inputs: 1 set of RCA inputs
• No. of outputs: 1 set of speaker outputs ( 4-16 ohm)
