Hello All,
I have decided it is time to pick out and build a tube line stage. I know there has been much debate over this, and I have read a lot of the other "pick me a preamp" threads. I have a short list of designs I am thinking about along with some questions on long-term projects. I will start with a list of what I am thinking, going in order of favorite to least favorite:
1. 5687 Preamp ( http://www.diyparadise.com/simplepreamp.html )
2. 6SN7 Preamp ( http://www.geocities.com/northbirdten/line_stage.htm )
3. Something involving the 12B4
4. 6T4 SRPP ( circuit by Poinz)
5 . Something else
The 5687 caught my eye because 1. it is simple... very simple, and 2. The Tube Depot has Tung-Sol 5687's on sale for $10 (though I have never ordered from them). The 6SN7 is a very close second because I have a couple handfuls of RCA 6SN7's laying in my tiny little tube box. I have heard good things about the 12B4 so that is why it is on the list. The 6T4 is up because Poinz seemed to like it in another thread, I am not a huge SRPP fan but there is a first for everything and I am open minded. Otherwise I am open to suggestions!
Before anyone shouts 10Y or 26, these are projects I have slated in my long-term projects notebook. I have this along with a C3g or 310A driven 300B, something large using a handful of my 12 and growing 807 stock, and I LUST after an amp utilizing the Telefunken EL156
. Anyways I have a couple questions for the DHT / IDHT preamp builders out there.
1. I an in the process of laying out (on paper) a choke-loaded 26, can the 10Y by choke-loaded or does it prefer a output Xformer?
2. How does the 27/56/76/264B(I have two, that's why I ask)/244A/ect... compare to the 26/10Y?
3. Any other suggestions for tubes of this class or are the 10Y/26 pretty much IT.
Thanks!
Cheers,
James
