I did Dave's EFB mod to the SA100 I mentioned and it was well worth it. You can read about it and my panicked brain fart when I installed one of my bias caps backwards in Dave's AK thread on the SA100.
A great upgrade to the amp. I highly recommend it. And now with better operating points on the output grids, I don't have to run 7189s if I don't want, and I plan on tube rolling a bunch of different 6bq5/el84 quads.

snip.... and I plan on tube rolling a bunch of different 6bq5/el84 quads.
All of the sudden there was an unprecidented demand from Nigeria for 6BQ5s and Byrd's stash was completely gutted, leaving notben to use whatever he could dig up out of the lower third, if anything.

Maybe the Teles are hiding in that bottom third.
I'm certain the Teles have all been sifted out by now and sent to the other room for long distance hoarding. There may be a few WEs, or Rad-Tel near the bottom, but no Tele for you.

I just thought I would post an update. I like the tube set in the Eico amp the more I listen. The tubes are all new production.!!!The JJ 12DW7 has become better balanced with more run in. The bass is less prominent and there is no more boom. The bass, however, remains the strongest of the 12DW7's I have used.
The mids have possibly richened a little. The sound seems fuller today even though the the bass has receded some. I am listening to Sherman Robertson "Guitar Man Live" and the guitar and vocals explode out of the speakers. The mids have definitely picked up some dynamic kick. The JJ EL84's are almost new too so maybe they have matured some as well.
The treble is well above average good. I don't like an overly detailed treble and any excess sibilance sends me running from the room. The JJ treble is detailed and smooth and the highs are just there .... well integrated with no spotlighting or edge. The treble is not as airy as with the Raytheon 12DW7 but the center image is tighter and more solid .... which I personally prefer. I could see where some could say the JJ is more closed in. But the tube is also more focused to me.
Again, I was pleased to begin with and I hear improvements to the sound as the tubes get more hours. I always avoided most JJ tubes because of reliability issues but the good JJ's are really good.

Post again after more hours. The JJ EL84's need time too..at least that has been my experience. I have been trying the JJ ECC803s and it is a nice tube too.
