geetarman49, You make some good points. I expect I may try and approach buying tubes assuming that I can always resell them at somewhat close to what I pay for them. One of the major difficulties with buying NOS tubes (after you determine which ones you want) is confirming that the tubes you find for sale, are in fact what you are looking for (i.e. design and manufacturing plant.) On a related note, I am getting my CBS Hytron 5814 12AU7 burned in (30-40 hours) and I...
Does anyone know enough about DAC/preamp circuits to know for sure if the Sunrise requires better than "driver" grade tubes. I found the following thread: http://www.audiocircle.com/index.php?PHPSESSID=s1pefij61khc2f7p6t9dnoqa92&topic=91642.20 where one of the respondents states: "With any of tube LFP-V Edition Tube boards (single tube), the "driver grade" is fine" I believe the piece of equipment they're referring to is the Isabellina HPA LFP-V Edition shown on the...
 Thanks for the reply. I misunderstood when I read your first post. You indicated paxmate but I was thinking plasticine. Thats what I didn't understand. Thank you, again.
 Could you describe a little what you did? I have been considering doing what I think you did.
 I just Googled catodamp5, the new product, and it doesn't appear that it is in production. The web store, Audio qualia does not have it in stock and I only got one other hit through Google. It is a thread in a turntable forum where one of the members apparently developed catodamp5. I didn't read the whole thread, but it appears some of the members dispute the dampening factor testing methodology and interpretation of the data.
If you like music and like to play with stereo equipment, I suggest you read up on modifying a pair of Fostex T50RPs.  There is a thread where Keith explains how to do it and someone on the thread will send you the stuff needed on the cheap.  It takes a couple of hours to do the mods and there are a few places you can get the headphones for around $100   I was planning on getting the HifiMan HE400 at $400 but ended up with the T50RPs and I'm happy as a clam. ...
      Did you use steps 1 thru 11 under "Simplified and Consolidated Pictorial for DBV #3" in the very middle of page 1 of the Incremental mods thread as your guide?  I followed these steps and I didn't need to open mine again to tune them.  They were vastly improved..   You should hear a significant improvement without any burn in.   First, if you're going to be working on these a bit, make your life a little easier by cutting out the four posts.  A set of side cutters...
I did look for an organ manufacturer's tubes but was unable to find a single cleartop at a good price.  This morning, however, I found a vendor on eBay who has a bunch of Conn cleartops that he is selling for $7.49 ea + $2 shipping so I have one on the way.   Presently, I'm still burning in the stock tube, the TJ Full Music, the basic Shuguang 12AU7, and the CBS Hytron.  I am getting some sense of the differences in these tubes but it will take quite a while just to...
geetarman49, you may indeed be right about the old tubes vs. new, that's why I want to hear the opinions of others on the TJs that I like so much. I plan to do a lot more listening and burning-in of my CBS Hytron and in the near future I will get a Conn organ RCA cleartop 12AU7.
 Please let us know what you think. I can't believe how good it is....I may go ahead and order another for spare.
