Nickel Permalloy 50 Silver SE45 worlds first production .
We have been working very hard to perfect this Line Level Pre Amplifier. The design features multiple stage power supplies , current and voltage regulated .
The heaters for the Single Triode 6J5 per channel are also regulated .
The Signal path is very pure and simple , input to the 6J5 grid then out via the Anode to a Lundahl Line Level Transformer copper or Silver Wired options for a 600 ohm balanced or Silver RCA output.
The performance is quite stunning, using high end Lundahl Amorphous C core transformers to set the impedance output gives a very pure sound, no extra tubes to impede the signal.
The 6J5 triode is a very linear tube and provides a big and open sound stage. Instrument's and performers move in perfect harmony across the sound stage with pin point accuracy .
Sound is very detailed but never bright , enough warmth to provide a very lifelike rendition of the original recording .
Excellent frequency extension across the complete range.
Up to five separate inputs can be ordered and XLR balanced output.
Silver input RCA's and Neotech OCC copper or Silver point to point wiring .
Obligato Oil and Polypropylene power supply smoothing capacitors , all other parts used are audiophile grade .
**A TKD Volume control with hand held remote option is available .
11Hz -40KHz -1dB bandwidth
RCA and Balanced output.
Distortion less than 0 .5 % THD or IMD.
Power supply ripple below 100dB.
Class A driven .
Line Input Transformer
1:1 FOR 'BALANCED BRIDGING' INPUTS
• Ideal for balancing any high-impedance unbalanced input
• Wide bandwidth: -3 dB at 0.25 Hz and 80 kHz
• Recommended for levels up to +19 dBu at 20 Hz
• High input impedance: 14 kΩ
with 10 kΩ load
• High common-mode rejection: 124 dB at 60 Hz
This transformer is designed for use in wideband line input stages. Distortion
remains very low and CMRR remains high, even when driven by high source
impedances. The primary is fully balanced and its terminals may be reversed
to invert polarity, if required. A 30 dB magnetic shield package is standard.
TKD Volume Control Option with hand held remote.
