6021 Amp project..looking for some input

Working on a "powerman" type build using 6021 subminature tubes. I have built a few prototypes with both a single push pull output and one with a parallel push pull setup. I can't decide one over the other so I would like to be able to "switch" the parallel 6021 in and out of the circuit.

I am thinking to keep the heaters hard-wired and the cathode and bias resistors will be a separate setup.

So that leaves 6 connections that need to be simultaneously switched off and on. That is where I am running into an issue...relays? latch circuits? 6 pole switch of some type?

Thoughts, suggestions, comments from the peanut gallery?

Thanks!
Tim
