question about tube placement on my tremoverb...

[glamboy69]

I just got a new set of power amp and preamp tubes form Eurotubes however one of the boxes is labled "Balanced Tube For Phase Inverter" also on the box it is labeled it goes into position V6, my question is I thought that V1(the one under the silver cap) was for the phase inverter. Also which preamp tube is for the reverb, i get a loud hiss when reverb is turned up. Thanks.....

According to your instruction manual, V6 is phase inverter and V5 is the reverb tube...
