Post Subject: 6E6P-DR in triode modePosted by Johann on: 7/13/2011

Hi Romy,
i want to use the 6E6P-DR (triode mode) as driver in my tube 45 amp.
I use a D3A (triode mode) with Anode choke at 180V, 12mA. Grid 2 is connected via 50 Ohm resistor to anode. Grid 3 (pin 8) is connected to cathode.
The 6E6P-DR (also 6E6P-E) and the D3A have the same pin layout.
If i look to your schematic of the 6-Channel Melquiades DSET Amp, where you use the 6E6P-E (triode mode) the pin 8 has no connection to cathode.
What should i do, if i use the 6E6P-DR instead of the D3A ? Should i let pin 8 connected to cathode or not ? The B+ voltage will be adjusted to 170V, 18mA.
I have too much gain with the D3A (mu=77).
Thank you. Johann
