Post Subject: 6E6P-DRPosted by Johann on: 7/14/2011

Hi Romy,
thank you for your answer. On weekend i will rebuild my amp for the 6E6P-DR. You are right, the tube datas shows that pin 8 is a screen. On D3A pin 8 is Grid 3 connected to screen.
I will try it with pin 8 lifted and connected to ground. I have bought 6 pairs 6E6P-DR. In your forums you mention, that the E version is not for audio.
I use cathode bias for driver and output tube. I have tried fixed bias for the output tube 45, but i didn't liked the sound. (LCLC-PSU)
I can not remove the cathode capacitor with plate choke or transformer, because then the Ri will rise extremly. I don't have the formula on hand but i think it is: Ri total= Ri * mu+1
My Classe CDP-10 has 2 Volt RCA-output, but with D3A the volume is too loud. At beginning the potentiometer has channel unbalance and when i turn it a little more it is allready too loud.
I have a small room 4m * 3.5m and use 100db Goodmans+Pioneer loudspeakers.
I like the sound with plate-choke or transformer loading best, but i know the drawback is full mu of the tube. I like my PSU with LCLC.
Give me 2 weeks for burn in, then i will report my sound impressions.
Regards Johann
