Finally got to drop in the nos Sylvania 6CA7 power tubes I picked up for the Traynor (YBA-1) last week. These tubes are massive, they make the old EL34’s I had in there look like toys. They sound incredibly full yet deliver wicked glassy cleans. I snuck in a nos JAN GE 5751 in a preamp slot as well. I’m in love with my Traynor again! Can’t wait to start playing it out of six 12” speakers.
