A number of years ago a question kept coming up about what Bob liked best in his Dual Rec. Everyone that played his amp here in the studio commented about how lush the cleans were and how smooth the other channels were and how much gain it had. We decided to make the kit available to everyone and we called it the "Personal Fave". The front end starts out with a long plate Gold Pin ECC803S for V1, followed by a Gold Pin ECC83S in V2, next comes a handpicked High gain ECC83S for V3, a standard ECC83S in V4 and a Balanced ECC83S in V5. Headroom and chime in Channel 1, Smooth and round in Channel 2, Completely over the top in channel 3. For the power section a pair of JJ 6V6S's in the middle two power tube sockets and a pair of the JJ KT77's in the outside two power tube sockets. These all run in the EL34 mode and in the tube rectifier mode with a pair of JJ GZ34's. So the default power tubes are the 6V6S / KT77 Integrated quad. With the customize option you can choose a different Integrated quad which is great if you like the Personal Fave pre amp election but would like to go a different route for the power section.
These amps are fixed bias with no adjustment other than the switch to go between EL34 mode and 6L6 mode. 6L6GC's, KT66's and KT88's are run in the 6L6 mode.EL34's, 6V6S's, E34L's, KT77's and 6CA7's are run in the EL34 mode.
