Rear Tube (power) is for a 6AS7/6080 socket. Bottlehead is nothing if not consistent in its attempt to carve out a distinct house style. Also a chip and a blemish as seen in photos.Ĭhoke mounting flange posts broke(plastic) glued it back together (by previous owner, also a builder and confirmed everything is mounted no broken components.) Headphones: Sennheiser HD650 Grado SR60i Etymotic hf5 Amps/DACs: Bottlehead Crack w/ Speedball (Telefunken 12AU7 > RCA 6080) Halide DAC HD JDS cMoyBB v2.
Doc says I should also replace the long black wire to the headphone jack with silver, which I will do when install the speedball. I upgraded all the wire to solid core silver, and put in a stepped attenuator. The wood base does have extra holes (where other upgrades were mounted, but then taken off by the original owner due to it not adding anything beneficial to the sound). Speedball and choke still to install, but Im just going to enjoy the basic crack for a while. So it’s in perfect working condition but looks are not perfect with wood housing.
Please note the HP jack here is a 4pin XLR. **********************************************************************************************įrom what I understand, this amp was originally from a builder - these are the upgrades in this amp:Ĭrack + Speedball + Solen output caps + power supply shunt + cree diode rectifier bridge + Alps pot + 4 pin XLR plug (for balanced headphone cables) + shielded case + copper shield between PSU and signal electronics + 1% resistors where possible. Please read the Description below carefully. I am hoping someone else can fully appreciate this amp. I am only selling for a matter of preference (e.g., Stock Crack sound). I bought this to understand the hype/facts about a crack with the speedball, and everything about this amp and upgrades are true. It's not the prettiest amp, but it's got alot of upgrades in it and I can say definitively that with the right tubes, it could go toe to toe with a kilo buck amp. A little lean/timbre was off at times emphasis in upper mids may contribute to this. I am to the best of my knowledge, the third owner of this amp, acquired here from Head-Fi last month. For your consideration is a Bottlehead Crack w/Speedball and upgrades.
