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.

Absolutely DO NOT put 6DJ8 tubes in this preamp! It uses 4 12AX7 or equivilent(ecc83, 7025, 5751) I have this preamp and this info is direct from the owners manual.
