Here is my prototype preamp. It is an SRPP design using 2, 6SN7 tubes. The power supply (the large box) uses 1 regulated HT at 315V and 2, regulated LT, one with an elevated reference.
The case was built using salvaged stuff that I bought at various electronic flea markets. Most of the components where purchased from Newark or parts Connexion. The design and construction is based on the Morgan Jones books
I have seen it work on the scope. I think I am a few weeks away from hearing music though it.
Cross you fingers! |
