Question 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?

Why not just find sockets for them and simply remove the paralleled ones when not needed? Sockets for those sometimes come up on Fleabay and I've used the old TO5 style op amp sockets with those also...
