Well executed, high performing simple designs. Add enclosure and attenuator. VTA Roy Mottram's SP14 is based on the same Akido circuit.
Single input tube preamp
I'm looking for options for a 1-2 input tube preamp. Space-Tech Laboratory in Canada has the type I'm looking for but I don't know anything about them. If anyone has direct experience with them, please respond. Otherwise, I like to know about similar builders of small, tube line stage preamps.
Balanced preferred but not required. Thanks for any responses.
