5902 submini build

Post by Jered »

On your builds using 5902 for power, are you connecting all three cathodes or just using one (pin 8)? If the later, are you connecting the other two and just let them float, or?
Thank you

There's only one cathode, but it's internally connected to all three pins (2, 4 & 8 ). You can connect to any of them but only need one.

Awesome, thank you very much. Any idea why they would design a single pentode with three cathode pins? I'm sure it makes it easier to do a layout. Other reasons?
Thanks Katopan

I'm only guessing that it gave them more flexibility for compact layout.
