According to the manual link you posted with phono if I'm reading this right there would be 9 tubes?!
Tube type and location
Phono Board
V1 6DJ8 or 6922 MC amp
V2 6DJ8 or 6922 MC amp
V3 6DJ8 or 6922 MC amp
V4 12AX7 MM amp
V5 12AX7 MM amp
V6 6DJ8 or 6922 Infrasonic amp
Line Board
V1 6DJ8 or 6922 Contour amp
V2 6DJ8 or 6922 Line amp/Bal amp
V3 6DJ8 or 6922 Line amp/Bal amp
Note: 6922 Tubes are preferred as they
have less noise and microphonics than 6DJ8s
