Lazarus Cascade Basic Preamp - What type of tubes?
I have a Lazarus Cascade Basic tube preamplifier and do not know what type of tubes it uses. There are four tubes of the same type, but there are no markings to indiciate the tube type. Thanks for any help or information you can provide.
Does anyone have schematics for it, Trying to restore one but can't find anything on it, A photo or anything from an original would be much appreciated, Thanks
The Lazarus Cascade Basic Preamp uses 12AX7 tubes in all four of the sockets. Two of the sockets are for the phono preamp and two are for the line-level (control) section.
