Description

Hi everyone, this ad is for a pre-built Bottlehead Mainline. This is an end game, TOTL amp. This is the 120V Mainline for use in North America (Canada & US). It is highly modified to maximize performance. Costs of parts (in USD) and sound changes as follows:

Core components in this build:
> Bottlehead Mainline - $1200 US - Price of stock kit

> Mundorf Supreme coupling caps (10uF each) - $120 US
-- Upgraded to give a nice clear sound, neutral, open sounding - gives big soundstage depth! Very fast and dynamic capacitor.

> TX2575 Naked Z-foil Resistors on the input path, stepped attenuators, 6C45 tube anode, and key regulation sites - $250 US
-- These are the best resistors that can be purchased. I had Texas Components custom make these at the precise values I was looking for. These resistors don't add or take anything away from the input signal. Give the most clear, precise, and un-colored sound possible. These are the lowest distortion resistors available today. Precision matched to 0.01% of their rated values. Incredibly low thermal drift.

> High frequency cylindrical ferrite beads placed throughout (especially on all power carrying paths) - $60 US
-- Further increased the blackness of the background. Increase in overall transparency of the sound.

Also has the following upgrade:
> Mills non-inductive wirewound resistor replacing metal oxide resistor in the high voltage path

Note: Has a small cosmetic flaw of bend in the aluminum near to the right 6C45 tube. Does not affect functionality whatsoever.
