These where purchased to use in my Dynaco mark III mono blocks and I can't use them due to the VTA boards I had installed. These are brand new un opened and sold in a set of 2 with free shipping. Just looking to get my money back. DESCRIPTION The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes.
