Bottlehead Crack OTL Tube Amplifier for headphones with Speedball upgrade and tweaks to let certain tubes work. Comes with 4 tubes.

Completely purchased DIY and built/painted on my own. Sounds great, no background hiss whatsoever because of speedball upgrade. Comes with Sylvania 7236 tube and E80CC tube. (amp's A, B resistors were modified slightly to let these tubes to work. RCA 6080 and 12AU7 tubes came by default and are not as clear/wide/bassy. If you'd like to try those you need to modify the amp's resistors back to stock. Very easy to do, only two resistors need changing. PM me for easy details. Currently the amp will work perfectly with a Sylvania and E80CC combo and it sounds the best I've ever heard from my tube rolling journey.) Those tubes are rare and expensive too! Great value for its price. Competes with the high end tube amps available from Woo Audio and what not. Great for Sennheiser HD600, HD650, HD800 and other high impedance headphones like Beyerdynamics.

Is a USA model (110 V) so I will ship to the USA only, unless you really have use for it outside the USA (message me if so). Bought in USA, but I moved to Greece a few months ago and am ready to part my ways with it. Beautiful amp. Used for a few months regularly in 2015. Not at all in 2016.

Spent a lot of time and money on it and since you cannot buy it pre-built, it's an easier choice for most to buy it over the DIY kit that Bottlehead sells new.



*FREE Shipping paid by me to the U.S.

I will talk to my local FedEx facility after the sale to get quotes and ship to the buyer's location (economy). It seems shipping/handling might be delayed up to a week because August in Greece is a holiday month and most businesses are very slow/closed all together.
