I have a question about my DSL5CR Classic Gain channel. I replaced the stock power tube with a 12BH7A-STR-TAD and replaced the stock pre-amp tubes with Genalex Gold Lion ECC83/12AX7 tubes. I biassed to 100mV. I now have no discernible gain in the clean channel. I can alter the volume, but even at full gain and full volume the tone is pure clean. Did I clean it up too much or is this normal?
Hello Steve,
Please can we ask did the DSL5CR work and have gain before you replaced the valves, if it did then one of the new valves may be faulty.
Kind Regards
