They appear to be based on the Mullard 5-20 circuit. EF86,ECC83 and a pair of El34's. You should get matched pairs or a matched quad.

Does anyone know if this amp will take 6CA7's and KT77's?

My winged C's are a matched quad as are my 6CA7's - happy to bob them round for a listen sometime Graham.
