Selling my full set of Cryotone tubes for the Sarah 300B amplifier.  Tubes were purchased earlier last year but my amplifier arrived on 2/13/26.  Tubes were put in amplifier to make sure they were in working order.  Tubes have less than one hour of use, essentially brand new.  Selling at around a 15% discount off retail price when purchased directly from Cryotone.  When I purchased the set there was a lead time of a few months; I know there are supply issues with the OC-2WC tubes currently (also stated on their website).  Price new is $2320, asking $1975.
