SOLD: Bottlehead Crack-a-two-a Amplifier and Rare Telefunken Tube

[SOLD, thanks for all the interest]

For sale is my Bottlehead Crack-a-two-a Amplifier (aka the Crack 2). I am the original purchaser of the amp.

The Crack-a-two-a is the big brother to the legendary OTL Crack amp.

Amp Description

Essentially the Crack 2 is Crack/Speedball amp with a much more sophisticated power supply.

In my opinion, the better power supply of the Crack 2 gives it better control and discipline relative to the regular Crack/Speedball.

For more information on the Crack 2, please see the Bottlehead.com website.

Price

I am asking $OLD for the amp.

Included in my $OLD asking price is shipping to anywhere in the CONUS as well as all of the included stock tubes.

Optional Tube

Also for sale is a rare Black Coat Telefunken G73R (12AU7) tube I purchased for the Crack 2 from Brent Jessee. His description of the tube:

"As rare as the famous ECC802S, these are the elusive black shield coated avionics/aircraft grade SELECTED TUBE made only for Agilent Technology and Hewlett-Packard. The G73R part number and RFI/EMI black coat shielding indicated the very highest grading. This indicates exhaustive after-market testing for low noise, uniform output, freedom from microphonics or physical defects, long heater life, and even, uniform cathode emission. Hickok tested, and then ear tested in a preamp! The finest Telefunken diamond mark smoothplates, NOS, is what these rare tubes are based upon. These have the G73R printed or hand lettered on the outside black shield coating, and were only available as spare parts for Agilent or H-P equipment. Critical use in hospital or aerospace test equipment demanded tubes with super low noise, and tightly controlled output, and these beauties deliver! The ultimate tube for tube mics and mic preamps! Very fine, very rare tubes, in great demand, especially this smoothplate version. All are the real deal, with the diamond mark in the bottom glass. These are rare matched pairs, with transconductance tightly controlled internally and from tube to tube. Incredibly accurate, the amazing sound image emerges out of a dead quiet background."

I am asking $OLD for the Telefunken G73R (12AU7) Black Coat tube.

If you'd like to purchase both the Telefunken tube and the amp I will sell both as a package for $OLD.

Thanks!

 

I think I heard this amp at the last Bay Area mini-meet. I thought it sounded like a baby ZDS. Had the same punchy, fun vibe as that much more expensive amp. Wish I had the cash on hand to snag it!

 

Goodness, that's one purty amp. And the tube is demonic!

 

Yeah, I'll be sad to see her go. Hopefully she'll make someone happy.

I'm trying to pair down my collection to potentially pay for a certain new headphone that costs a metric crap-ton.

 

Bump, still for sale.

 

SOLD! Congrats to the buyer!
