Tubes
Your Alchemist comes with a matched pair of 6L6 power amp tubes depending on availability. Five
12AX7/ECC83 tubes are used in the pre amp. See below for individual functions.
Note: If you want to experiment with different tubes, you can reduce the potential for amp noise by 1)
choosing lower gain tubes, and 2) placing any higher gain tubes earlier in the signal chain (the signall
flows in order from V1, to V2, etc.).
• V1 - First stage, Channel 1 and Channel 2 / Second stage, Channel 1
• V2 - Crunch stage, Channel 1 / Second stage, Channel 2
• V3 - Third stage, Channel 2 / Fourth stage, Channel 2
• V4 - External FX Loop / Internal FX
• V5 - Power Amp Phase Inverter
• V6 & V7 - Power Amp Tubes
