Mike, Moving on from Alex's thought of taking the adapters apart, how about these?  The source I found them on was out of stock eighth item down, but if you find them elsewhere it make the change far more compact. Hi Chris This appears to be very similar, if not the same, to what I mentioned previously as being used by Telstra. The top screw on cover will have a cable entry hole in it.
Regards Alex

oh wow, this looks interesting. I am going to watch this thread with baited breath (fishy).

Friedrich, I meant to add... the "red fingers" are no joke mate..... this past year my hands have turned as red as beetroots and freezing cold to the touch (even on a warm day), it's got to the stage where I have to wear fingerless mitts to keep them warm and "hide" them from public view  I've got this thing now where I am looking at people's hands and comparing them to mine.... everybody else's hands seem so "white" Luckily, my face isn't red too or I'd have to wear a balaclava as well |

Hi Mike...... ...this some interesting tube.What you mean would it work in my X10D buffer to??But I have one question!How to know wich leg is anode,wich grid and wich cathode if I want to covert this in 9 pin socket? I have newer before play around with this subminiatures tubes. Hi audiorado, Yes, they will work in an X-10D.... no problems at all. If you have a look at this diagram you will see what goes where:  I am looking at the bases that Alex and Chris have mentioned and it would be a lot easier converting the bases than bending the valve wires all over the place..... get the base converted and then it would be a simple case of soldering these direct onto the converted base..... the base would then be known as a sub to noval converter.... or, in this case, a 7963 to 6DJ8 pinout converter. I think that's the best way to go..... I'll order some bases up and do a step by step "pictorial" of what goes where..... give me a couple of weeks on this. All the best, Mike. |

Mike, Moving on from Alex's thought of taking the adapters apart, how about these? The source I found them on was out of stock eighth item down, but if you find them elsewhere it make the change far more compact. The picture doesn't tell the full story.... it shows the pins but doesn't show any sockets.... I don't think these will be of any use. What we need is an 8 pin socket and a 9 pin base in a housing..... we, then, need to be able to solder wires from the 8 pin socket "internally" onto the 9 pin base.... The socket you have found would STILL require bending the leads of the 7963 into spaghetti junction. I'll draw a diagram of what we need but I don't think such a "converter" actually exists and it would cost a bomb to get one made and the limited "stock" of the 7963 would possibly make it a totally fruitless endeavour. So, to sum up...... we need an 8 pin socket which is totally independent, we solder the 7963 onto it without having to resort to wire bending / funky angling etc....... We THEN need a 9 pin base.... we then need to be able to wire the socket to the base AND support it with a housing..... nope, no such device on planet Earth unless I am losing my marbles All the best, Mike. |

If the plugs that Chris and myself mentioned were still available, you may have been able to do the "spaghetti" bit, then carefully enlarge the cable entry hole so that it slipped over the tube, thus concealing the "spaghetti" ?

Have you spoken to your GP about this ?

x2! I didn't realise you were trying to avoid the spaghetti, my find would just lower the height of the conversion. Alex's suggestion is also sensible or even fit an eight pin socket to the top of said cowling. |

Hi Alex, Yes, I have spoken with my GP and the "may be" cure is total abstinence from alcohol. I have asked for 25 further opinions Mike xx |

That test bed looks like a sunrise/horizon. Number 2 of 4 which is "still" on sale A really popular amp by all accounts? I would have thought number 2 of 4 would be up there with the Mona Lisa............. |

I think I need to "decrease" the blood flow to my hands...... they are far too red as it is........ |

Greetings! Is anyone willing to sell a couple of these tubes already mounted on a 9pin socket saver? I can't solder anymore because my sight is going down the tubes...pun intended. Please pm me if you would like to sell a couple.
Thanks!
Doug

If you check out a recent post by Mike you will see that at present his eyes are even worse than yours, and likely to be for several weeks at least ! Regards Alex

Sorry to hear, Mike. I've located a source on ebay so perhaps I'll break out the hakko and give it a whirl. The tubes are only $20 each. Hope your eyes get better Mike and thanks for the info, Alex! Doug |

From where you get the 7963? Gives a datasheet from it? How much it costs? PS: Its cold at your home, you have 'red' fingers that imagine that  Hi Friedrich, Here is the datasheet: frank.pocnet.net/other/Sylvania/Sylvania-SSFGT.pdf scroll down a little bit until you come to the 7963. I don't, personally, sell them but Alex mentioned there were some on sale on ebay and I found this guy: www.ebay.co.uk/itm/NOS-NIB-Sylvania-7963-Frame-Grid-Medium-Mu-Twin-Triode-Vacuum-Tube-/151156917123?pt=Vintage_Electronics_R2&hash=item2331a78383Seems it's not much of a discovery as his listing mentions the fact that you can use them as an alternative to the 6DJ8 Oh well, it was a new discovery for "me" I only have six of them. All the best, Mike. Just thought I should point out that the 7963's in this ebay link although listed as Sylvania are in fact stamped Philips as in the photo, not Sylvania as in Mikes photo. I followed my curiosity and ordered a pair (be surprised if I was alone in doing this  they arrived today. |

I followed my curiosity and ordered a pair (be surprised if I was alone in doing this they arrived today. Hello, As far as I know Philips bought Sylvania at some point so there should be no difference. I purchased two of them too but they are taking a long time to arrive (tomorrow I guess). Mike, I am following this thread with great interest, have you tried them in MF XCAN V3? How it compares with 6h6p in it? Regards Maxi |

The tubes arrived this morning. Soldering them in the adapters has been a real nightmare, but I am not very good at soldering  . Furthermore I made a mistake with the pins so my advice is checking twice. I have tried them in a Counterpoint SA-100, my DIY DAC with a Broskie Cathode Follower and in an Earmax Pro. The tubes don't work properly in the Earmax but in the other circuits works beautifully although I haven't enough time to listen carefully. Anyway the sound is very promising. Maxi |

I soldered one up but couldn't get it to work. The pics that Mike posted look opposite of what the pin out shows but I'm hoping the image was reversed. I was hoping to get confirmation before trying again. |

Hello Doug, Any pics? Well, I am not very proud about their appearence so...I think better not to show them  But basically are like Mike's ones but in "other (ugly) fashion" .
I have a diagram but I can't attach the image. Sorry. You can make it yourself with two concentric circles being the inner the 7963 pins and the outer the 9 pins one. Draw it from the top view. Then draw the lines between the pins following the previous posts indications. Be careful when you find the first pin because in this tiny space is very easy to make a mistake. I did it.

Doug,
I forgot to remark that the tubes diagrams are always from bottom view. Sure you know it but I tell you just to be sure. I propose you redraw it from top because I think is easier for soldering in the adaptors.
regards
Maxi

Sorry guys, I haven't been logged in for a few days so have missed most of the recent developments. I had drawn a diagram to upload but it seems to have disappeared!  It can be quite confusing getting the pins of the 7963 in the right place.... Alex, what you have to do is to mirror image the 6922 socket so 9 becomes 1 and 1 becomes nine.... remember, the diagrams are showing the valves "upside down" so when you turn them the right way up the actual lead outs are reversed (if that makes any sense?). I'll do another drawing and upload it as soon as I can. They are not the easiest of things to funky angle but well worth the effort as they sound pretty damned good! |
