Hello,

This is a Bottlehead Crack 1.1 with Speedball upgrade installed.
Everything is already assembled and functioning fine.
I personally assembled (have professional experience) it with silver-plated copper wires as shown in pictures.
Based on the tests I've done, I personally did not like the Speedball upgrade compared to stock, but it may just have to do with the stock tubes and that is all I have--less than 2 hour run time total on amplifier
Includes the 2 stock tubes, GE 6AS7 and Baldwin 12AU7 tubes, and power cord.
Also includes 3 extra fuses just in case, stock unused wires that came with kit, and the resistors removed for speedball kit. 3K ohm resistors have extended leads (in case you want to revert the bigger of the 2 boards back to stock) but 22.1K ohm resistors leads are too short to be reused.
I added thin layer of clear coat to transformer cover for rust prevention


Will be packaged carefully to hopefully avoid damage during shipment. . I can email you the assembly manuals PDFs in case you need any troubleshooting.
Note: the main plate does not secure down to the wooden enclosure, it just rests on it.

Please submit any questions via PM

Price: $480 + shipping to CONUS. I will cover PP fees.

Edit: Price Drop 500 -> 480
