Would like to see updates when available. Thanks, JS

The is the very best information I have ever read on this topic! Thanks for the time you have spent in sharing your knowledge.

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...

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...

Thanks again. I had no idea anything like that was happening in TN. I will make every effort to go. I have good and bad days. Just getting over chemo. Last year was given 30 days to live. I have been clear for a year not. I appreciate you letting me know. Best, John

I spoke too fast. I did not realize that we had a Bottlehead forum. Thanks again for the information. Best, JS

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...

I bought this amp from a member, however, I have not received a reply from him regarding this component. This piece fell off the amp and I am having trouble knowing what it is and how to replace it. I am attaching photo of the component as it was attached to the amp and also a couple of photos...

Sorry, I did not notice the date. I am sure this tester is long gone. Thanks

Charlie, Is it an A, B, or C model. Do you have pictures. If so please send PM and let me know how much you are asking for it. I live in Nashville. Thanks, JS

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

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...

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...

Have you every used the 6f8g as a power tube?

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

You have a very good friend. They should all work in the Darkvoice - in either the front or rear positions. Best, JS

It was great to have found this post. I have been trying to find information on hardware based parametric or graphic eq for use with headphones. I am currently using Seenheiser HD800 with Bottleneck Crack amp. I use an Oppo DVD as source most of the time. I have been somewhat reluctant to...

Mr. chef8489, Please accept my sincere apology. I am an old man and just did not adequately read the detail of his message before replying. I should have read it again after your reply, but alas I did not. Again, please accept my apology, JS

He is looking for information on a tube, the 6H8C - not on his amplifier. Information about that tube, substitutes, etc. can be found on the Bottlehead Website. Unless I am missing something somewhere, I am confused about the value of the comment. Good listening, JS

You can find information on substituting the 6H8C on the Bottlehead website. Bottlehead.com

I believe I had the front and back reversed. Don't know what I was thinking. Sorry, JS

I am afraid that the Darkvoice is in the closet. I am using a Bottlehead Crack. As much as I liked the Darkvoice I do prefer the Crack. I just have not been able to bring myself to sell the DV. Maybe soon. I did order the Tung Sol. It should sound great in the Crack. Best Listening, JS

I do not believe that it could be anything but: back socket - Input from source front socket - Output to headphones I still have a DV and found it to be a wonderful. It was the first really good headphone amp that I owned. I did really love the shaded RCA 6f8G (with adapter) It had such a...

Please do not think that I was in any way being critical of the Audeze LCD-2 headphones. I am a great fan of the LCD-2s and love the planar sound. They remind me of the many pairs of Maganapans that I have owned. I am in my 70s so have had plenty of time to go through some speakers. My...

I really appreciate everyone that liked the PM-1s. I thought the sound was outstanding but the comfort factor would keep me from purchasing. The ear cup just did not fit my ears. I can wear the HD-800s for hours and feel no discomfort at all. A bit larger ear cup would make the PM-1s...
