HI DL,
The pinout is different, so even though the tubes are the same size and have the same amount of pins, it will not work.
The easiest way to find out if the pinouts are compatible, is to go to the Radiomuseum site. As an example, just type in Radiomuseum EF86 in the google search box, and it comes up. Under the usual picture of the tube you have a diagram of the pinouts. Just compare each letter and location to see if they are identical or not.
This is the pinout for an ECC88 tube:
This is the pinout for the EF86 tube:
As you can see, the pinout is very different and not compatible.
