A Saga, the story of a Schiit upgrade

ALL212

Ladies and gentlemen,

I give you the Schiit Two Holer



This is a socket saver for lift above the chassis and a 6SN7 to 6J5 adapter.

The 6SN7 is a dual triode and the 6J5 a single triode of the prior generation.

mhardy6647

ZOMG, you drank the 6J5 Koolaid!

ALL212

If one glowing ember is good two must be better!

mhardy6647

I think I have -- a few -- 6J5s downstairs.
Just sayin'...

ALL212

Lots of black metal ones on the bay, not so many glass.

Let’s see... BH Crack kit goes on sale, I was planning a custom plate, I’ve built one with 6SN7 instead of 12AU7. Make one with 6J5’s?! Just need to add a hole and plan wiring.

mhardy6647

Why not go for the gusto and use a pair of 27s?
Or 56s or 76s...

ALL212

27 and 56 would be rough, have to drop filament to 2.5v from 6.3v. Not sure if the tranny supplied could handle that. Now the 76...hmmm...already 6.3v filament. Need a couple of 5 pin sockets and real estate. Loose a tad gain...

Maybe I'll post that up on the BH forum and see what shakes out.

mhardy6647

Yes, forgot about the filament voltage, derp.
I was thinking pure-play DIY -- then you can just add another transformer (or two)!

ALL212

PB from Bottlehead thinks the 76 should work with a resistor change to get the plate current up.

DARN YOU!! Now I gotta rethink this...AGAIN!!

Drawback...Only 76's will work ever in this Crack... No going back (would have to replace the socket).

It would be neat if that thing rotated slowly. Does it? Can it?

ALL212

PB recommends this... (I like the way he thinks!)

So, you could start with this adapter:

Then plug in this adapter:

Then plug in a pair of these:

If that weren't silly enough - here's another stack...

Holy... What the [bleep] is going on over there?!?

Just Aaron spending too much time in the solder Flume....

mhardy6647

It's an amplifier!
It's a Jenga game!!

They should charge extra for that.

ALL212

I didn't get the motorized version...sorry guys.

If I put the 76 tube adapters on top of the 6j5 adapters we'll really have a sight!

pitdogg2

better get the mirror ball option with it as well....

Well Schiit,..... it's still impressive!

All joking aside - and with this bunch I know how futile that effort is!

If you're looking to roll some tubes in the 12AU7 line (and the other 12's as well but I'm not as familiar with them) try these adapters and go for completely different tubes.

12AU7 - same as 6AS7 but different pinout and socket. Get the adapter!
6AS7 - 6J5's but single triode instead of dual but still in an octal socket. Get another adapter and 2 6J5's for each 6AS7
76's - best leave this one alone. Pinout and some current differences.

They all come in from China and suzier.electronic is the one that I buy from.

Have you noticed any sonic differences with all the tube rolling? I was under the impression that due to the way that Schiit chose to implement the tube buffer portion of this preamp, that tube rolling wouldn't really have much if any effect on the sound.

ALL212

The Schiit Saga does use the tubes as a buffer. But not a half arsed buffer, it has full rail voltages so the tube is fully engaged when switched in. Some buffers are half arsed...

On the Saga you can switch between tubes and no tubes with a single button on the remote and I've been pushing that button a lot. I ran 1/2 dozen...10 different 6AS7's through it. There is a slight (one click) volume increase when going to tubes and that can cloud judgement.

But with a good 6AS7 (or the 6J5's) there is a definite soundstage and presence improvement. It's close to "won't really have much if any effect" but it does make a difference and a positive one. Call it subtle...

That's ALL I need is more TUBES....lol.

I will give it some thought and check the space under the hood of the Avant

Cool, thanks for the insight!

An older thread, but a good one.

I also modded my Schiit Saga preamp. I pulled the stock Wima caps and replaced them with Mundorf EVO Oils. They were extras, and fit perfectly in place. My Supremes and Supreme S/O caps were just too large. No dynamat on the relays. I thought about it, but the clicks don't bother me. My son hates it...!

After only a couple of hours of play time, WOW. A nice different. More expansive in all directions. Better micro detail, less blurring of musical passages. Multiple instruments, playing together, are now separate and distinct. A little bright in the treble, but hopefully that'll settle in, after more playing time. Well worth the change.

Thanks for the inspiration!

I also modded my Schiit Saga 1.1 preamp. I replaced the MKP10 WIMA caps with Vcap Odams. Immediately more dynamic and musically flowing sound which only got more refined at about 300 hours of music play time. The biggest headache was getting all the white LED's to go into the holes in the faceplate.
I also replaced the 6SN7 tube with two WWII 7193/2C22 "Mickey Mouse" tubes - WOW! Not going back to a 6SN7 here.
For good measure I upgraded the fuse with an SR Blue blue.
Saga preamp sounds better than the $2000-3000 Joule Electra and Muse vacuum tube preamps I owned earlier.

Nice job and welcome to the forum, stick around and stay a while.
