    George, not only do I love the name "Telefunken" but looking at their history, they made some of the finest tubes ever and they last forever and they sound wonderful.

    I know of atleast one esteemed old timer here who hates Telefunken tubes.........I don't understand . I will say they are very neutral tubes and overall don;t give you that syrupy, ultra warm feel some of the other tubes are noted for. To me Mullards are a bit to bloated and syrupy whereas German tubes in general are tighter, flatter in the mids and more accurate while maintaining all the tube sparkle and a huge soundstage.

    H9 - Thanks for the additional suggestions. I'll definitely look into trying them at some point, when the right auctions come up. I'm especially intereseted to try a different type of rectifier. I don't have any complaints with the Brimars and old RCAs I have now though...

    Oh look, those Tele's are "on sale" for $240, down from $600.

    Regarding the dampers, since you said you only use them occasionally, you must have noticed some negative effects from them. Can you expand on what you've heard, please? For the 3 pairs of tubes I tried with the dampers over the past couple days, I didn't notice any negative effects. I thought the soundstage actually widened a bit. Some songs it seemed noticable, others songs, not so much...

    The only reasons I don't use them regularly is because I was rolling quite a few tubes lately and I'm lazy and, the dampers I use tend to scrape the lettering off the tubes, that's the main reason. Too many times on and off and the labels are gone, especially on Telefunkens. If you get a TFK and the lettering is robust and hard to scrape off, it's almost always a fake. TFK's usually have delicate lettering that easily rubs off.

    Ok, I see. Good to know about the lettering on the Telefunkens. What brand of tube dampers are you using, H9?

    Keiko - Have you had any problem with removing lettering with your UltraSonic 9's? I would think the way they roll on/off should be gentle enough, but maybe the lettering is more fragile than I think...

    Don't recall ever having a problem with the lettering rubbing off on my tubes, but many of mine have faded labels already. Just be careful when handling. I have a pair of Dyneema gloves that ScompRacer sent me and use them whenever I'm rolling tubes.

    Edit: Linky.... Exactly like these and they're perfect whenever handling tubes.

    Guys,, I cannot tell you how happy I am with the Bendix 6106 and the Sylvania's (5965) in the Dared,,the only other thing I've done is to replace the input caps with those Russian caps,,I'll document everything when the Obligatto's arrive,, it seems that the synergy so far is very very good,,partially due to luck and Brock & Kieko's push in the right direction.Stay tuned,,and if I've inadvertently thread crapped,I apologize in advance.I will now start the "official" Dared Sl2000 modification thread,,and would appreciate some participation/input from ya'll.

    Thank you kindly

    George, I'm glad you are enjoying the Dared and I'm glad I could help out with some recommendations. I really, really like this unit and when I first bought it, I never thought it would be a keeper.

    Looking forward to the modification thread but I am a little confused. When you say "input caps" are you talking about the (4) Yellow Carli caps or are you talking where the Auricaps would be in a unit like mine?

    So far the ones I've replaced are in the spot that your Auricaps are,,I used some Russian PIO that I had laying around--mine were so large they had to be mounted to the inside of the chassis--I'll start the thread this w/e--so yes to the question.The obligattos will replace the 4 yellow caps in your pic.

    I was so impressed with the Sylvania 5965s that I picked up a second pair as backup. Excellent bass extension and very tight. At 10.00 each, it was a no brainer. Are you using the Gold Brand, George?

    nope-- same ones as you have--and I was thinking about picking up another pair too--the synergy with the Bendix is off the charts good.

    Which rectifier Larry?

    There are two you simply must have besides the Bendix 6106 I'm sending. The RCA 3 mica bp's I'm sending also have a different tone than the TFK's you just bought. You need to get yourself some Hamburg made Valvo's (ECC81's) for sure. With all that you should be set to get rolling............. Most Valvo's aren't from Hamburg, they are rare so I can help you if find some you want to purchase. Again, not available stateside very often. I get them from Germany usually.

    I'll PM you some sources for the other rectifiers. The thing is with the old rectifiers you need to get them when available, becuase many times you won't see them FS again for awhile. Most dealers don't carry the 5Z4 rectifier and the ones they have are junk in almost all instances.

    I've bought from Sweden and Greece to get these rectifiers. Very hard to find to impossible stateside.

    I'll second H9's suggestion on the Hamburg Valvo's. With his help I scored a pair of them a few months ago. In fact, Larry, I think you might have heard them in my Dared when you came over to my house. I can't remember though, because I was a tube rollin' fool at that time. I roll tubes less often now that I have a few pairs that I really like...

    I still need to try the Bendix 6106's.

    Thanks, H9 for this Telefunken 5965 rec. Drank from the cup today and it goes down smooooth. Top to bottom near-perfection.

    One thing I had noticed with a couple other tube combos that I really like was that they do LF bass tones/thumps/beats and anything acoustic, regardless of frequency, remarkably well, but were a tad murky-warm on electronically generated tones in the midrange. Not offensive; and I often like the slightly more aggressive bass they provide. But these TFKs just do it ALL well with balance, clarity and sweetness that is sublime.

    Thanks for sharing your find here.

    *bump*

    Had to bump this to add another sleeper tube to the list for the Dared SL2000A.

    Not a holy grail tube, but an inexpensive tube that sounds wonderful. A wolf in sheeps clothing.

    IBM stamped (for computer use, made by GE) -1959/60 - 5965 long gray plate w/large halo getter. Got these on the cheap knowing ahead of time they were made by GE. Came in original IBM boxes with IBM computer part number, NOS.

    Not quite as fat sounding as the early Sylvania black plate 5965's, but these have a wonderful midrange, tight bottom end and sparkly highs with really nice air. And they are relatively cheap too.

    Go get 'em.

    So glad you bumped this thread to the top with the recommendation. As you know I am contemplating a inexpensive tube preamp and one of these days I am just going to cave in and get the Dared......

    Do it, you won't regret it! As H9 has said, and others can attest too, that little unit really responds to tube rolling. But be warned, you should probably be prepared to spend some extra cash on multiple sets of tubes... it's addicting!

    Default Another very happy owner...

    Hi all - Started reading this thread just prior to my ordering a new SL-2000A from Joe - Lots of useful information in these pages. Loving the preamp after upgrading the rectifier & 12AT7 tubes to carefully chosen NOS types, and now driving a pair of digital mono amps into Magnepan 1.6 speakers. (Matter of fact, the rectifier I settled on is a wonderful improvement over the stock tube, and very affordable. Thanks again for all of your insights and sharing your experiences on enhancement recommendations :-)
