- Here we go on a small journey of tube rolling which just means changing the Vacuum tubes for different brands. these are all "New Old Stock" tubes from the 50's and 60's from different parts of the globe. Today only a few places make Vacuum tubes, Russia makes the lions share of all the popular named tubes, and they all come from the same factory the Reflektor plant. They vary by little details between brands , then we have JJ Electronic of Slovakia makes some very good tubs now, and before 1989 TESLA was the brand from this company. then there is Shuguang, or Chinese tubes, which have never been good tubes they sound just OK for the most part and are made cheap with thin glass and break all the time , Just recently they have made a push with the Pavane brand which is an attempt at making tubes that compete with Europe and some of those are good tubes, but often overpriced in my opinion. trimming that out are a few specialty companies for tubes like Sophia Electric, Elrog, KR Audio, Emission Labs to name a few boutique, very high quality brands.
So Ours for this purpose are unique and in the case of the CCA very rare indeed.

I watched the video and I’m now interested in tube rolling. I have the Romulus Signature Edition. What is your overall impression of that dac. I use it with the Mimas integrated.
The 1950’s Amperex longplate Bugle Boys are my favorites!
I may have some , Ill look . ;-)
Just a thought Mike...you should be able to buy an adaptor socket to use a 6sl7 provided the ax7's are wired to use 6.3 volts(ac or dc)...using 6.3 volts both tubes draw 300 ma...
Where are your telefunken ecc83 smooth plates? to my ears the most neutral ecc83 you can get.
That would now be the JJ factory Micky 🤙
Red tipped diamond logo smooth plate telefunkens are awesome..
hi ,great video .ive made many comparisons on guitar amps ,i think that you are using mullard i63(shortplates,made 1964-1974) tubes so the bass is too upfront for home audio ,those are great for guitar amps at v1 and all positions really. previous versions (i61 f91 f92 mc1 made 1955-1964)are much better,more balanced with magical top end. i suggest any mullard made before 1964 or ge 12ax7wa.
Right on man, thanks for your feedback !
@@OCDHIFiGuy GE 12ax7WA green letters is one of the best tubes ever made, I was shocked when I heard it for the first time, as I was trying to match a single GE 12ax7 that came with one of my vinatge tube amps.
I have the problem I can't fix. My speaker sound statically, and scratchy, I have three different sets (Elec, Polk both are new, Old set of Maggs. Amp/intergrade Yaqin ms-20l, Mcintosh 6900 (has been service, was thinking this was the issue) and belles ref 350. Change all cables (power speaker). Source DAC, and CD player (sent signal straight to preamp or integrated amp). Got a Monster Power AV unit, still same old problem. Thinking its got to be power from the wall socket ?
Amp . check that
Which one the most forward vocal tube?
imaging is affected hugely too...dynamics/life are affected too...ty brotha
In a big way..
Tesla blue tip from the '32' factory
Sounds scarce..
@@OCDHIFiGuy The factory 37's are a lot easier to find in blue tip. The blue painted tip is ultra tight, .5% matching in every domain. They were painted blue for the MIL use.
Man you audiophile guys crack me up, 100$ a tube lol i scored an old scope full of basically brand new GE and amperex tubes. Guy i bought it off of bought the scope new used it maybe 20 times and put it away... "new" doesnt mean shit when it comes to sound quality, you could get a NOS tube thats microphonic out of the box haha
Tesla....they look like an at7 with a small plate...can't make the plate out...some mfgr's make some that use a plate that looks like a 6dj8
The octal versions of the 12ax7 = 6SL7..is a much better sounding alternative to any 9 pin versions...Ty anyway...alot of differences in the ax fam
Wasnt that one more soft sounding and tubey ?
@@OCDHIFiGuy no...some sound that way...just like any other tube u must audition first...have lots of the same ones....back in the late 70's I found a local surplus electronics store that had an inventory of industrial and commercial and vintage vacuum tubes(50,000 pieces)...As soon as I found his NOS(in the boxes) AX7 Telefunken large smooth plate tubes I purchased all 50 pieces for 75 bucks...I cooked each tube first and tried em all in my buddies "Audible Illusions" preamp ...out of 50 tubes 15 of em were audio grade...even some of those were absolute best....
@@OCDHIFiGuy I used a stacked totem pole driver usin a "Sylvania" JAN version 6SL7/VT229 staggers plate tube that was direct coupled to the grid of an indirectly heated power triode duo horizontal deflection video tube...I tried dozens of different ones of these(6SL7) before I found the perfect sounding one...I find the video versions of tubes(6LF6,6EM7,etc) are more consistent in sound then the other kinds...
I have a pair of killer NOS Mullard ECC35 tube (6SL7) I bought yrs ago...just checked the price of these on fleabay ...one pair had a buy it now price of $685.11US and another pair they were askin $2092.69 US...
And those are probably the counterfeit ones...lol. I only get tubes from people I know personally ...
@@OCDHIFiGuy Unh,unh...I looked at some high quality photo's of em...before buyin...they came in the right boxes too...plates are vintage with staggerd plates...I bought a relabelled Russian 6sl7 that was branded Mullard and got burned...I do alot of research before I buy now....
@@OCDHIFiGuy I also didn't buy myne from flea bay...it was a private deal ...Ty for the info brother
