hizzieallen Posted June 25, 2021 Share Posted June 25, 2021 (edited) In my never ending quest to thin out my audio collection. Today I have for sale a pair of RB-81 and a Tec-On model 55 single ended tube amp. $250 for the speakers $250 for the amp. I’m in the Silver Spring MD area and would prefer local pickup.
