    Crack;Bottlehead OTL

    I am currently listening to the modified crack using a GE 6080 with a chrome metal base (the only one I have ever seen). I am using an 8SN7GTB Sylvania (less current than 6sn7) with an eight to nine pin adapter. It calms the 6080 and produces wide sound stage. I am using Sennheiser HD800S for...

    Crack;Bottlehead OTL

    I have two Cracks. One highly modified including Speedball and one with NO modifications - NO Speedball. I have used a 6F8G and a 6C8G as a power tube on the Crack with no modifications (IT WILL NOT WORK ON A CRACK WITH SPEEDBALL). I believe it provides a much smoother tube-like sound even...

    Help with Bottlehead Crack component

    Thanks to both of you for you sharing your expertise. One more question. I will probable give replacing the cap a go. Does polarity make a difference with installation and if so is there an easy way to identify the positive side. Also, in order to make a more secure connection, would it make...

    Darkvoice 336i & 336SE Tuberolling PartII

    I was tempted to buy the La Figaro but went for the Crack instead. I now have two Cracks (one highly modified) and the Darkvoice. I keep the Darkvoice as a backup. Thanks for sharing your photos. Best, JS

    Darkvoice 336i & 336SE Tuberolling PartII

    While I do not recommend it to anyone else, I have used the 6F8G as a power tube in the place of a 6AS7 in my Crack without Speedball. For some reason in the other Crack I have with Speedball, it does not perform very well. As a power tube it really runs much cooler than for instance the 6080...

    Darkvoice 336i & 336SE Tuberolling PartII

    I have been an advocate of the 6F8G tube for use in the Darkvoice earlier on this Forum. I have since switched to a Bottleneck Crack. After trying many tube configurations I still find that the 6F8G/6C8G provides the best sound as a front-end tube. I especially favor the Tung-Sol 6F8G. These...

    I still have many - about 50 - tubes. Many will work in the Crack. Most will work with an adapter. There are some that I would sell if you have interest. Best, JS
