Perhaps you would just end up associating music with pain.

Well done.  Keep it up.  I will be back in a couple of weeks I hope.

Again Sennheiser have let down Australians.

Hello

Depression has increased. I won't be losing weight for while. Good luck, Paul!

Looking into the M^3 and gamma 1, but am open to suggestions. What projects are you working on ATM?

Glad to hear that people's tubes have started arriving. I really appreciate the impressions that you have posted. It's great to get other opinions and gear matching experiences. I wish I could have kept the Crack. The matching with the Beyer T90s is one of the most synergistic systems I have...

Well done! I will be posting exercise routine weekly rather than daily.

I will be following this thread with interest. 

Thanks to all of those who have expressed an interest in my tubes.  The remaining items in my treasure trove have been moved to eBay (have sold the amp that uses them).   http://stores.ebay.com.au/Winter-Cottage-Books/Audio-Tubes-/_i.html?_fsub=6093602015&_sid=1070780425&_trksid=p4634.c0.m322...

An online food diary?  Not a hope.  I am not that obsessive about my wight loss!   Can't argue about its importance, but I don't want to waste all my time on weight loss.

That's a great idea, Paul.  Things like this area always easier with some encouragement from someone else in the same position.  We could give each other mutual support.   How do you want to do this?  I have thought of a couple of options:   1. I could edit the initial post to include your...

Tube rolling skeptic? Don't bother reading this.    Believer?  Read on!   "Goodbye Crack" tube liquidation!   I'm auctioning off all my tubes, gents.  Could be a chance to get some rare and awesome tubes for $20.00.  Silver plate Siemens ECC82?  Check.  Chatham 5998?  Check (in the form of...

I have mine for sale if anyone is interested. 

+1   Don't expect a huge change in sound, just a tweak.  All tubes sound great in this amp.

BYW - I do notice a difference in tubes, albeit subtle.  Worth spending the money to optimise the sound of something you already love.  The difference is in more than EQ IMO.  Think speed, clarity and sound stage.    Just don't go to the extremes that I have!

My love affair has ended.  The flame just burnt too brightly and too hot.  I have pulled my hand back from the fire.  Goodbye Crack.  How I will miss thee!  Tube rolling has been my joy and my bane. 

It is not uncommon for there to be very small particles of debris, even glass fragments, inside the tube.  They generally do no impact performance.  Look very carefully just to make they are very small.   Cheers

Anyone interested in any of the following tubes?   2 x Chatham 2399 - NOS white box 1 x Osram 6AS7G round brown base - NOS NIB (sold) 2 x Mullard 6080WA - NOS NIB 3 x Tung Sol 7236 - NOS white box 2 x Bendix slotted graphite plate 6080WB - NOS white box (1 sold, 1 left)   I have purchased about...

Hi everyone   It is time for me to part ways with my Crack.  Unfortunately, its name was prophetic and I have truly become addicted to tube rolling, so much so that I am going to have to take the SS route for a while.   Anyway, please let me know if you are interested in any of the following...
