There was an article in AudioeXpress describing a nice 211 SE design with Mercury rec tubes. I have been following the build up of that design and it appears it has reaped quite a reputation. Nothing like the big bore triodes. Anyone have experience with these tubes?

For 845/211/GM70, etc. project, you can consider the new "Lundahl" LL1688 OPT. From "K&K Audio", price is $275, not too bad. And for 2A3 & 300B projects, 1664 serie (with 50mA,60mA,80mA,100mA DC current) is nice. They are 3k:8 Ohms only, price is $125. The only drawback with "Lundahl" OPTs is that they are "naked and ugly" - for under-chasis montage, or buy some separate cover? I have 1664/80mA OPTs, some experiments are on their way... ![](http://www.audioroundtable.com/emoticons/smiley.gif)
