AUDIO-ANTIQUARY - ART OF TUBE SOUND
The Wood C3M vacuum tube line stage preamplifier.
This preamplifier was created to be an invisible part of the system, it will not influence the sound of your system - well, it will, in a most natural and transparent way.
Frequency range 10 - 50.000 hz within +/-1dB deviations.
The amplification factor for the Audio-antiquary preamplifier is a 6 or 9dB option to custom order.

The design is only one stage, triode, no negative feedback, output transformer line stage preamplifier. Based on a beautiful German Post tube C3m, probably the last generation of the best tubes built ever. It's triode connected pentode, powerful enough to provide 1w of output power.
But the real heart of the pre amp is its output transformer. Misho spent 1 year designing and prototyping it until he was absolutely happy with both - measurements and sound. It's double c-core based, Hi-B silicone steel, and its core can be safely used in a 10w pp amplifier.
Point to point wired with pure copper cable with the shortest signal path optimisation.

This tube is famed as "perhaps the best small signal pentodes ever made..." Built exclusively for the German post, these are special quality - 10,000-hour pentodes for use in AF and RF circuits. They were used in repeater amplifiers for long-distance telephony in the 1960s. The lowest noise and lowest microphonics plus very high amplification were accomplished with this ULTIMATE preamp tube.
Single-ended & Balanced transformer output option available.
