Hi Sinusoids
The mechanical arrangement of your amp is clever in that the two chassis have their open side out for easy modification and repair.
The only questionable facet is the heat of the power tubes between the chassis may cause accelerated aging of the preamp components. Maybe a fan should be added if there is not one already. This can be a 12Vdc fan operated from 8Vdc generated from the 6V heater.
