Yeah, miss Roger Modjeski - what a treasure he was. He was the master of tube conservation. Gave me a good tongue lashing for biasing my RM10 wrong and set me straight for an hour on the phone. Never wore out or shorted a tube in over 10 yrs on my unit. Sorry I sold my RM10MkII. He wrote on his forum "don't worry about handling tubes w/bare hands just get the peanut butter off your fingers". Just got a matched quad of EL34's from RAM tubes yesterday.
