I have a number of SED "Winged C" 6550 tubes that I acquired several years ago, and I have now sold off my amps that could use them, so I am willing to part with them. Most of these are NOS, and test as such. I purchased all of these brand new, and have only used the one quad marked as such. Prices are listed for the sets presented:SED 6550 ("Winged C"): from The Tube Store; still NOS - $260/quad [4 pieces available, all tested an Amplitrex AT-1000 tester by TC Tubes, with values shown. Note: these run high in iP and Gm, and will work fine an a manually biased amp with enough range; do not try them in a autobias amp - - they could tax the power transformer. Photos 1 & 2.] Etched date codes are 01?? / 0233 / 0514 / 0824. SED 6550 ("Winged C"): from The Tube Store; USED, test new - $180/quad [4 pieces available, all tested an Amplitrex AT-1000 tester by TC Tubes, with values shown. Note: these run high in iP and Gm, and will work fine an a manually biased amp with enough range; do not try them in a autobias amp - - they could tax the power transformer. 3rd (last) photo.] Etched date codes are 0725 (x3) and 07?3.
