Tube Locations
As you can see in the picture below, the two larger tubes go into the 8 pin sockets.
The tubes should be matched and it makes no difference which one goes on what
side.
The two smaller 9 pin tubes are of the same type. They are either 6N1P or 6922, often
supplied in matched pairs, meaning both tubes are of the same type. If this is the
case, then it makes no difference which tube goes in the front or the back position.
If you plan to get creative and try mixing it up a bit, by installing one of each, the front
tube is likely to have the biggest impact on the sound. The rear tube is what we call a
follower so it adds no gain to the signal, just a lot of torque. Often we see users
placing a 6922 in the front location and a 6N1P in the rear location but reversing it
changes the sound too.
The sound of these interchangeable tubes are as follows:
6N1P - warmest, smoothest, most forgiving
6922 - slightly less warm, more dynamic, tighter focus
