For Sale:
SOLD. Fully assembled Bottlehead Crack + Speedball + tubes + stepped attenuator

Will Ship To: Anywhere

Hi all, 

 

Recently picked up a Bryston BHA-1, and the fully assembled Crack has been seeing less and less head time so I'm thinking of selling it.

 

Comes with:

- Bottlehead Crack + Speedball Upgrade

- Walnut stained wooden chassis

- Black coated metal base

- Valab stepped ladder attenuator

 

Power tubes:

- Original power tube

- RCA 6AS7G grey plate

- Sovtek 6AS7G

- Russian 6AS7G (can't remember what brand it was, will have to look it up)

 

Input tubes:

- Original Input tube

- Mullard (rebranded Rogers) 12AU7

 

Misc;

- 90deg angled RCA connectors

- 90 deg IEC power cable

- Bottlehead badge, still new.

 

Hit me up with some offers! Low ballers will be ignored =). 

 

SOLD TO @san7

Pardon my ignorance, but what does the step ladder attenuator do?

He upgraded the volume pot.

E: Look at the bottom right of a stock Crack and then look at his. smily_headphones1.gif

yep! what MrEleventy said is correct. Basically instead of using a carbon pot to track volume for each channel, this one has matched resistors so channel imbalance is a thing of the past, even at low levels.
