In the Thread: The RCA’s 6C33C sockets?

Post Subject: That’s all that mattersPosted by Romy the Cat on: 3/24/2012

Paul, I can’t say anything about it and I invest zero trust to what the seller say. The fact that he insists that “customers have never returned any or complained of their quality” does makes me horny however. The socket at your picture does have name Johnson on it and it is all that counts – no one would face the $5 worth socket if they sold 100 per year.

The truth is that the ceramic pieces are absolutely irrelevant. What is relevant is the shape of the pin contacts – something that is absolutely impossible to say from picture. The Chinese, Russian and anyone else sockets have the contacts shaped that when they embrace the tube pins then the contact surface is pretty much a single narrow point. When you put the tube in and look at the pin-contact interface behind strong light than you will see that there is a single dot where the metal of contact holds the tube pin. The Johnson and RCA contact is the same but the pin-contact interface has a shape of not single dot but a small surface. It is just a bit longer for a few mm and has slightly different angle. That is all that matters.

I use the Johnsons in Milq and for 8 years I use the amps I did not have any problems with pins. I do not mind to go to basement and to find my Johnson and RCA sockets and tell you their numbers. However, no one said that ONLY my sockets have that proper engagement of the pins. It is possible that other Johnsons models do the same. So, if I were you than I would buy from this guy one socket, get it, inspect it and compare it to the Chinese socket and if they do have property flat/cylindrical connection with the 6C33C pins then I would get as many from your seller as you need.
