which 6sn7 tube for my wyetech topaz amp

5692

Above is probably as good as it gets, no affiliation with listing party.

Good Listening

I use an RCA smoked glass and really like it, more on the romantic side but leaves no detail out. I use it in my dehavilland.

For what it's worth, I agree completely with Peter. RCA 5692 is the best I've tried with Sylvania 6SN7 GT a semi close second choice.

RCA is more dense, sightly better dynamics and beautiful “flat" top end. Sylvania will be ever so slightly more extension which may or may not be desirable depending on tonal balance of entire system.

Of all the 6sn7's I have and I have most of them, I always go back to the sylvania 52 bad boys in my preamp. The red base 5692 are also very nice.

In your amps it could be a different tube, but these two are a good place to start.
