Supratek Tubes and Tube Swappin' for Everybody


I will have a Supratek Chenin in my set up in a day or so. Since so many folks are rolling tubes around here I was hoping to garner a comprehensive list of everybodies favorite tube compliments. Be it NOS or NIB or WLATB (Whatever's layin around the basement)
Being that the "Deal of the Century" thread is a little more like a novel I figured this would be a good place to post questions and answers related to one subject of Supratek amps and pres.
On to the subject of me. I don't have immediate plans to swap tubes as I've figured that Mr. Maloney would supply us with something listenable for the break in period. But, since so many have reported such dramatic improvments I want to ask this question:
What is your favorite compliment for quietest gain and dynamics in the phono stage?
I will be using the Chenin exclusively for vinyl ( I don't have a CD player) and listen to loads of early rock and roll and Jazz bands, smaller jazz bands mostly, quartets and quintets. Some classical, the usual Beethoven and Mozart, but usually just a lot of loud garage rock.
Ok, now lets see what happens.

Bwhite,
great comprehensive post !
Is Bendix 6106 better then Philips Miniwatt GZ34 (which I'm using) for Chenin ?
For short time I had WE350B I had impression that sound was too worm, I have warm monoblocks, so what is the best way to have a little more highs (what tubes) without sacrificing anything.
I'm using Ken Rad Black Glass VT231,Philips Miniwatt GZ34 (rest is stock).
Sorlowski - give the Bendix a try. It is a somewhat inexpensive tube too.

The WE350B's are not exactly warm on their own but when paired with the GZ tubes, they can be...

The Early(1950's) RCA 5V4G (ST Shaped - black base) tubes are a more open sounding rectifiers. I think these are available NOS for under 35 bucks.

I think the GZ34's (as well as most other Mullard GZ tubes) are too muddy sounding. While the Metal base GZ34 is one of the best rectifier choices it pales in comparison to the Bendix.

Now.. when I first got the Bendix, I hated it. It did something strange to the pace of the music - everything seemed awkward. I think others who tried the Bendix at about that time had similar experiences. Once I burned in the Bendix though, everything came into focus. The Bendix is on the warmer side of neutral but the bass is tight, detail is there, the dimensionality increases substantially. Pace is correct. Its a great tube.

Like I said above. Burn in the Bendix. Just disconnect the power supply from the line stage, insert the Bendix and let it cook for a week or more. Every day or so, give it a listen and eventually it will outperform anything else and stop sounding weird.

Another good thing about the Bendix is that it's a slow starting tube and does not stress out the other tubes when it heats up. Some of the Mullard GZ's start fast and in some cases blow fuses on Supratek's. This stresses out the other tubes and shortens their lifespan.

The Ken Rads are good tubes - very organic -rich and warm. Changing these with Raytheon VT231 or Tung Sol Rounds will add more transparency & detail but you will lose some of the midrange magic, weight and round-ness you like with the Ken Rads.

Another possibility is the RCA 5692 red base tubes. I really wanted to like these tubes because they do many things well but for my system I felt they were too detailed and I personaly loved the warmth of the Ken Rads / sweetness of the Tung Sols. If the rest of your system is warm sounding, the 5692's might work for you. Great bass, good detail and dimensionality.. just not "luxurious" or romantic.
Amazing, this is exactly what I was hoping would happen. Looks like we can all get into bidding wars on ebay now. I just stopped in to check this and will be reading more closely later, when by the way I will be listen to my new Chenin! I gotta go pick it up at the hold center a ways away cuz I got drunk and slept on a friends sofa last night, obviously missing the Fedex guy, damn.
I'll have a few more questions too, I'll get to those later.

But the Bendix does not work for the Chenin, only for the Syrah! There is a small change in the PSU according to Mick. It was mentioned to me a year ago when I ordered my unit. I think this was covered on the other thread as well. I still have the tube. I bought it new and tested NOS but it is the only rectifier that I tried (from the many recommended at the other thread) that produces a "chugging" sound no matter what source is selected or what tube combinatons are employed on the other circuits.

I hope someone can confirm my experienced as well.
Amandarae - that's a bummer! I wonder what changed in the Chenin power supply that makes the Bendix 6106 not work. Well.. the people with Cortese's are lucky.. you can use the Bendix 6106 and the Mullard CV181's Two great tubes which do not seem to work in the other Supratek's. Actually maybe the CV181's work in the Chenin - I know they do not work in the Syrah.
