[R-390] 3rd mixer

Sat, 04 Jan 2003 13:43:19 -0500

Hi,

How is the rest of the socket wired? Obviously somebody has moved the plate
connection off of pin one ....

With a pentagrid converter in there all sorts of odd things are possible.

Assuming it looks like amateur work my vote would be to document it and then
switch it back to stock. The 6BE6 is not going to be as good a mixer as the
6C4.

    Take Care!
