Removed the cage to replace the tubes…
Removed the power tubes in order to get at the preamp tubes…
Two of the preamp tubes are tucked behind the transformer…
The preamp tubes are set low and directly on the circuit board…
You can see here the circuit board tube sockets…
I didn’t realize the Mark 5:35 had a fan in the chassis…
Resetting the preamp tube housing was tricky…
Very tricky…
With all the preamp tubes replace and rehoused, time to replace the power tubes…. This is much easier…
All done and tube cage back in place
