Value of 1W, R67 near the footswitch socket, measures about 1200 ohm but
overheated colour bands look like 11 ohm ?

The polished stainless steel control panel has the legends only silk screen
printed on. No more durable than the white markings on valves/tubes. On/Off
and standby legends already worn off.
What is the recognised way of ameliorating this, remove pots etc, clean off
panel with very weak solvent and spray varnish over ?
