Default micro pre amp

a few years ago i acquired a Croft Micro pre-amp from an employee of Glen Croft,who had it upgraded by Glen himself.From other sites i found this to be not unusual as he upgraded the Micro several times. What i want to know is does anyone have a diagram of the basic Micro which i can purchase.Also can anyone help me identifi one of the valves as the print has worn off.
There are 4 valves in my Micro,2 ECC83,1 5814a and the one with the print missing is EC?????.

Hope some one can help.
