Tekton Double Impacts

Thanks muzikmann, I knew it was a new poster to thread here and I should have taken the time to find the posts. And yes, the fact that David Berning uses it as his personal amp says a lot. Of course David is using the 6b4g in his ZOTL design. So many amp options and so little time......dare we bring up the Lyngdorf as yet another option?

Just in the for what it's worth category if any of you have an interest in EL84 amps for your DI's or other speakers ( I have Daedalus Argos V2' s)

I recently decided to give one a try (I'm an impulsive shopper)  and picked up a Finale Audio (sister company of Triode Lab) 7189 (2) integrated amp 20 wpc, though Frank at Finale said mine measured 22 wpc with the upgrade to Hashimoto output transformer vs the standard Hammond. I also had them upgrade to Mundorf silver in oil caps, and DH Labs RCAs. The amp can run EL 84, 7189, 6BQ5, or 7189A & EL84M.  I have about  70 hours on the amp and after about 30 hours I swapped in NOS GE 12AX7's and a RCA 5AR4 for the JJs that it came with, I left in the NOS Russian 6N14N-EBs (7189A equivalent) , though I just received an order of NOS GE 7189A's from Brent Jesse and will give them a try at some point. To my ears the amp is musical across the board with good separation and retrieval . I listen primarily to smooth jazz, blues, classic R&B, and some classic rock. 

I have been using the Berning 6b4g amp now for nearly a year. Mine was the first 6b4g amp Berning built. In fact he has even etched his signature on the amp. 

In the past I have used Dehavilland 845 Aries SET monoblocs with their Mercury preamp, a Rethm Gaanam amp, Vinnie Rossi’s amp, a customised 2a3 SET amp using Dave Slagle components including his nickel based output transformer along with his auto former vol control

I personally feel the Berning amp is way ahead. It captures all the magic of a 2a3 SET amp along with great extension and amazing dynamics. 

@premnath - that's some very nice amps you've owned. Very impressive the Berning 6b4g stands well ahead of those. You indicated they are built to order which explains why I haven't been able to find anything on his website. Can you confirm the specs for us? Someone mentioned earlier the Berning 6b4g is PP, output of 10 watts/channel and it costs $7K?  Thanks.

Hi Aric,
I can see the advantages of a parallel SET (PSET) design. One issue I’ve seen raised concerning this parallel configuration is maintaining equal power sharing from each tube in the pair. Apparently there’s a tendency for one of the tubes to become dominant and the other tube provides lesspower/current output.

Audio Note has been making PSETs for a long time and I assume that they have solved this problem. It seems that some other PSETs perhaps not. PSET 2A3 or 300b would seem a very good fit with the Double Impact/SE.
