Clean Channel Preamp Tube

Post by npo12354 » Sun Nov 01, 2020 10:29 pm

Hi all!

After too long of a hiatus, I was recently able to bust out my Dual Rec 100 watt Solo Head (non multi-watt) and it still sounds as beautiful as I remember.

After playing for a bit, the clean channel began to experience volume swells and so I believe a preamp tube is the culprit. The only problem is that I can't remember which preamp tube is associated with the clean channel (V1 A, V2 A, V2 B, V3A...). Can anyone share some insight into which spot is associated with channel 1? I looked at the manual but couldn't find where it explicitly states this.

Thanks in advance for any help!
