[QUOTE="Hasren, post: 918976, member: 21201"] Thanks for sharing the article and the proposed design for the preamp. As I have indicated I am a novice when it comes to tube designs or even coming up with a topology of any design. The best I can do is to build a well documented design. So far I have realised that I have taken a challenge of the best of the two worlds (i.e. Tube preamp matted with Solid State Amp :mates:). Therefore, reading the article I am inclined to go with any design considerations that would ensure minimal output impedance (with minimal compromises if any). I picked up a suggestion of an active tone control with a cathode follower or two-stage circuit to ensure low impedance. I am not sure if this is doable. So here I am relying solely on the advice of the experts out there :notworthy: With regards to Balance Control, I have read some article advising that it tends to affect the sound quality. So in this design, I would advise against it. Otherwise best sound quality is the ultimate goal :groovy: [/QUOTE]
