Thanks for the info. I have been pleased with the 6dj8 unit so far, but now is the time to try out several designs on my bread boards before I commit to a single design.
Not a big fan of the sound of the 12ax7, but I haven't used any for a while, so maybe it's time to listen again.
Actually I was pleasantly surprised at how low the hum level was with the 6dj8 with ac on the filaments. I may go ahead and switch to dc after I listen for a while though to see if how much difference there is.
