Referring to my very recent acceptance of the 6E6P as a tetrode to drive the tweeter:
http://www.GoodSoundClub.com/TreeItem.aspx?PostID=5329
I decided to today to stick my beloved 7721/D3A in place of the 6E6P – thanks God they have the same pins l...

The 5E6P is the same as my 5E5P only with more or less military ambitions and with congenital “western” pins layout. It has more fragile specifications and more tight tolerance then 5E6P but it is the very same tube. There is very very very minor...

[quote user="Johann"]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.Th...

I did have the Déjà vu feelings about it as I felt that we had this conversation in past. Here we go – it was a year ago.

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 hav...

Roman,Thanks for your prompt reply!May be my last wordings have misled you. I didnt mean I was interested in expetimenting gas tube biasing for D3a or another tube. Instead, I am rather interested in putting a gas tube biased 6e5p in front of a ss am...

hI bRIAN, [quote user="Brian Clark"]The 834P was a revelation for me, being a circuit that I would have dismissed as "old hat" (Feedback? 12AX7 cathode follower? Do me a favour!).[/quote] Me too, but you know me, i'm mainly pragmatic. The EAR 834P is...

Besides the single driver Aporia (which I haven't heard) I don't think Silbatone has made any speakers. So they don't 'employ' GIP drivers. I think GIP is a separate Japanese company who have just been invited to participate at these German show...

Hello Roman,Hola from Hong Kong! How are you? Haven't been here for long time. I have a question at the back of my mine for long time, and it may have been covered elsewhete in your blog before. I am asking it here but do point me to the thread if it...

Frank Blöhbaum, from Sweden I believe, have designed for Thorens a preamp that I think the first outside of Russia commercial use my 6E5P tube.

I do not know if Frank reads this site but if ...

The basically the same tubes. The 6E5P has own unit pins layout with heaters connected across the tube – very moronic in my view and it does not allow twisting the AC filament wires to the very end. The 6E6P has a common pins layout that most of west...

Hi Dima,Thanks for your comments; please forgive the chaos of what follows as I have to rush!
Agreed on all counts - the dc bias point would need adjustment and monitoring; I supposse it depends on how stable the electricity is from the wall; anothe...
