Can you please help me identify these two octal tubes for me.
The first one is a Motorola with a 1-2-4-5-7-8 pin out. On the base it says 5 4 6 W, the digits being written vertically.
The second is what I believe is a 6L6 type RCA tube with a black plate. On the glass it says RCA 7552, the last digit being barely readable. What variant of the 6L6 family do you think it is?
