Tube socket for ECC88, drawing

[peranders]

This is the very first tube thread for me

I'm searching without success for mechanical drawings for tube sockets for ECC88. Is there a standard for tube sockets or can the pin placement for the socket vary?

 

[SY]

The socket placement is, of course, standard. But there are LOTS of difference mechanical configurations.Typically, one buys sockets and measures them, then does the PCB.

So the socket pins don't always are directly under the pins on the tube?

No, they are a little bit spread out. The only exception I know of are the teflon UX4 sockets. These are not, strictly speaking, actually made for PCBs, but they can be made to work.

Pete Millett has an eagle library on his website with good tube stuff. So does Tubelab. If you want to know what not to do, look at the tube libraries that come with Eagle.

I'll think I'll start with this socket

BTW: Have you seen my and Mr. Ruschkowski's high-end adapters ?

 

[peranders]

I bought the RH21 socket from Mr. Svalander. It was quite easy to make a footprint

Just wondering, the tubes are shown in "bottom view", right? I have followed the internal wires in the tube and think I'm right here. The tube is E88CC from TAD. This is my very first tube project ever, this "tube buffered gainclone", my take. Rhys' project got me inspired.

Yes, the datasheets show tube from the bottom. In case of ECC88 it is easy to orient by following heater wires (pins 4 & 5).
