Schiit Saga Tube Rolling - Page 6

post #76 of 84

I'm curious about the idea of using an adapter from 6SN7 to 7N7 - which are supposed to sound great be cheaper - but all the adapters I found online require rewiring into the pre-amp - literally replacing the socket... is this the case? Is there an adapter I could drop into the existing socket (in Freya? when it finally get's to Britain) - that would be awesome!

The 7n7 uses a loktal base but is electrically identical to a octal base (6sn7). I suppose you could modify the 7n7 tube by crimping spacers to the pins to increase their diameter so it makes good contact. The pin spacing is apparently identical.

The Kenrad VT-231 and Sylvania 1952 6SN7GT chrome domes I have sound similar (great bass, slightly less transparent).  I've settled on the KenRads in the gain stage for now.  If I use those tubes in both stages, sound starts to get a little syrupy because I think they just compound each other.

 

I have CBS Hytron 5692 (brown base) and RCA VT-231 grey bottles on the way to try out too.

 

How does the 5692 sound as input buffer in the Freya?

It says 7n7 to 6sn7 but LOOKS like a 6sn7 to 7n7. You might have to just take one for the team.

I guess this will Be the Saga/Freya Impressions thread until someone create a Freya Thread. My Freya is on the way (Although it will be here on Friday when I am out of town) Monday is a Holiday for me so  I will have some time to play Once I pick it up from the fedex store.

 

Yes, I'm only rolling NOS.  I've tried new 12AU7 and 12AT7 tubes before and was never impressed.  Granted, they're not broken in yet, but I'm not impressed with the 1980s NOS Russian tubes that came with it either.

 

In my experience, the buffer stage has less impact than the gain stage, but it can still muck up the sound if you don't put transparent tubes there.

You mean in the gain stage?  Don't have them yet, but will let you know!  5692s are supposed to be some of the best.

Not the output gain stage, but input buffer stage? My 5692's haven't arrived yet either

Got my JAN-CHY-5692 brown base for my Saga. Wow! Soundstage is also very wide like the RCAs, but the biggest difference is the slight harshness from the RCA GTB is completely gone! Only CON is that the price is getting insanely expensive for a 5692 brown base.
