Unhappy Copland CTA-401 - early layout ?

I have purchased an early version of the CTA-401 as the print layout in the amp and the schematics found are quite different: no relais-driven input, a smal separate print mounted vertically and the power supply capacitors are quite different to the pictures I have seen.
Question: I need a tube layout description (5 x ECC8n) on the print - some without name - are they all ECC83 ?
Has somebody a schematics with the values ?
Thanks.
