Solder directly on tube?

DragonMaster · 16th May 2006, 03:47 PM

I forgot to buy a socket and I need to finish a project in a few days. Is it possible?

guitvinny · 16th May 2006, 03:52 PM

Je te le conseil pas, j`ai deja essayer, car c`est du fillage assez gros (la pin) donc ca prend du temps a chauffer. De plus, moi tout ce que j`ai réussit a faire c`est casser la pin d`un tube de 25 $....

donc non acheter toi le socket a la place.. ca en vaut le cout

For english folks, i said no...

Actually I did this once when I was in the same situation and too impatient to wait for the sockets to arrive. I wrapped solidcore copper wire around each pin and tried to solder them to the steel pins of a 6922 tube. Even with a 80watt iron the solder wouldn't stick to the pins. But I still got the components connected and it did work, though I dont recommend it. Not a good and longlasting connection. But if desperate enuff...

Right... I' trying the same thing with an Amperex 6DJ8...

I wouldn't, particularly if it is a genie Amperex. You should be able to get sockets quite quickly from a variety of sources.
Maybe Audio Marginal in Quebec can help. (I think they are still in business.) FWIW I agree totally with quitvinny, amusante cette texte en francais.

In a pinch, I have used the socket pins from a Radio Shack RS-232 connector, with some heatshrink tubing shrunk onto each socket pin. (Rat Shack has heatshrink too) Works real nice, and they are gold plated socket pins.

In fact, it worked so well, that I now use this method for a curve tracer setup, where I can pin configure the "socket" for any tube type quickly.

Soldering directly onto tube pins will likely crack the glass vacuum seal.

Il marche bien pour les Octals.

I've used it for the 802 pentode, socket for it seems to be almost unobtainable. Otherwise, alligator clips are the way to go, but I wouldn't suggest this without suggesting to BE CAREFUL with the high voltages, alligator clips can jump out of their place if aren't placed carefully, and maybe hit your face

For octals, you can use tip jacks to make a re-configurable socket. You have to file down the plastic collar at the top so they don't bump into each other for adjacent pins.

Hi SY,

Unless you need to replace the tubes at some point! Ever work on an AMC tube amplifier product? Not fun. (EL34's)

I don't recommend this.
