New preamp project is online

[Joel]

I finished my latest project, a transformer-coupled 6DJ8 preamp, and put the pictures and schematic on my website.
I'm really enjoying it so I figured someone may find it interesting.

I don't know (and I'm lazy to look) exact specs for that Lundahl-but in my tests I have better results with one whole ECC88 envelope per channel (both sections in parallel,with separate grid stoppers);I don't remember exact working poin,but I remember that I like it pretty hot........ 😉 and-yes with OA2 in stab. (one OA per channel) .

you can see my WOT if you click bellow on www mark


hehe-now you know what "signal energy preservation" means......

The Lundahl is rated at 10mA, but can be run at 12mA or slightly higher with lower output levels. I'm running each half of the 6DJ8 at 12mA in this circuit.

JEpstein, I'm in Park Slope. 16th St and 7th Ave.
