The WVA Series 5 has a different valve line-up to the Series 4; Rectifier is an EZ81 and the bias and erase oscillator has a push-pull arrangement using an ECC85.

WVA 5 Manual is here but is missing the full circuit diagram..

The amplifier circuits are similar to one half of the stereo CBL 5 and a copy of that circuit is here..

Hope this helps,
