I'm actually quite amazed that ardent Shads fans would want an amp without at least an EF86 based channel - as opposed to a purely EF86 based front end. In my view, such preamp arrangement is the source of one element of an authentic Shads sound up to and including Wonderful Land. Note the use of the word "authentic"... not "good" or "close" or "acceptable" ...
It's possible to buy an original 60's Vox at more or less the price that Music Ground (JMI) are charging for this modern kit...
And whilst the sounds that Hank achieved on the Cliff tour were better than his previous attempts, they still fell short of what other folks (notably Colin Pryce-Jones) are able to achieve on a daily basis...
My tin hat is on... shoot!
