Here's an update on progress. I managed to pull the chassis/tube from the cabinet, (see pics). the gasket around the tube surround is still soft and in good condition. The chassis components look OK with no major heat damage or other mishaps. I now realise the valve that has gone to air with a crack in the base is a PCC89 in the socket for V4 (6BW7). A replacement 6BW7 will be ordered. I will check all the other valves shortly for the correct types. I have dismantled the cabinet, removing the front glass, bezel and liberally treated the woodworm infestation in the front baffle. The woodgrain effect appears to be a painted/printed effect in a dark brown. There are some deep scoring that's removed the grain effect. I was going to paint in the 'grain'. The varnish appears to be a cellulose lacquer - is this correct? Work on cleaning and recapping the chassis will start once the cabinet is sorted.
