Anthony, I have an unexpected advice to you. Label all knobs, testing points, input and outputs. Everything sounds to you very logical and self-explanatory not but, so it was to me. In 12 years you will be looking at the thing and wondering where is the knob to adjust the DC at DHT stage and where the specific testing jack for a specific 6C33C bias is and how it differ from the testing jack for 6E5P plate. I am 48 and it is not that I am having Alzheimer’s, yet, but with touching it for years the thing like this run out of memory. So, ether label everything of make the test point and knobs map  and put the map in some kind of save place inside the amp. 


Most definitely yes to the labels.  The analogue meters will have a mix of fullscale deflections (250mA, 50mA etc.) and therefore I have to make new 'labels' for their internals and on each of these labels will be the channel name (Upperbass, Midrange, Fundamentals etc.).  There is a local signwriter that I use from time to time and he will make up some nice decals to put on the steel panel above the knobs to identify the channel.  Similarly, the stepped attenuators will have not only the channel but the attenuation marked.

I half struggle to remember which is which now so in a years time I might have no clue at all.
