SOLD: FS: Bottlehead Crack Headphone Valve Amp w/ Speedball Tube Upgrades

Recommended Posts

Item: Bottlehead Crack with Speedball Upgrade and Tube Upgrades (Chatham 6080WA, Brimar CV4003)
Location: Melbourne, VIC. Will ship ($20AUD Australia wide)
Price: $700 ono
Item Condition: Excellent
Reason for selling: Upgraded to Crackatwoa
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:


This headphone valve amp was built by myself in December 2018. I've used it up until November 2019 when I upgraded to a Crackatwoa. An excellent amp for high impedance cans such as Sennheiser HD650/600, Beyerdynamics and ZMFs.


This will come with the stock tubes (RCA 6080s and GE input tubes) as well as tube upgrades for both the output and inputs: Chatham 6080WA and Brimar CV4003, all NOS when purchased. This combination of tubes gives a punchy and musical sound with a little bit of sparkle, yet losing none of the rich mids that valve amps are known for. The Chatham 6080WAs are sonic equivalents of Tungsol 6080s, which are ridiculously hard to find and are one of the most popular tubes used on Bottlehead Cracks.


The finish is a Scandinavian Oil with a spray painted dark grey metal top plate. (There are some imperfections in the spray painting).


I have other tubes that can be sold either together with the amp or separately (not included in the purchase price). All NOS and used briefly for testing.


  • GEC 6080 - +$200 - a much warmer, sweeter tube than the Chatham 6080WA
  • Tungsol 5998 +$200 - enough said... 
  • Tungsol 6080 +$100 - punchy, musical

Haha. Never know. Even though it's Level 1, I couldn't do it!

I was probably comparing the Crackatwoa build to the Crack... ? the former being much harder and in more recent memory.


Anyway, PM if you're still keen..
