OK guys, I am moving forward with the design for the 'Analog Bridge' tube buffer.
I have a lot going on right now, so be patient, but I do believe this product 'has legs'. I am working on an enclosure design and the first product will be RCA in and out, one set of inputs, probably two sets of outputs. No volume control. It will be a buffer/impedance matcher with very low distortion, wide bandwidth tube circuit. It can be used between any source with built in volume control, straight to your amp. It can also be used between any passive preamp/attenuator and amp.
The two things that this product will bring to any system, is the 3-D body and weight of tubes as well as an excellent impedance match to your amps. With an ouptut impedance of < 100 ohms, it is ideal for this purpose.
Target price is $750 with (2)6dj8/6922/7308 tubes.
Once the initial design is out and I see how it is received, I will look at the following options:
Volume control (w/bypass)
I want to start with the simplest and cleanest design concept first to prove its worth and success.
