A matched quad, or two matched pairs, of TJ 300B/n mesh plate output triodes
They date form 2011 but have been in storage for most of that time and have less than 50 hours use
They test, work and sound very good
£250 per pair inc shipping, or £475 for both pairs inc shipping

NOTE: The specs suggest they are equivalent to the original WE 300B with 40W max dissipation and 450V max plate voltage, however it is recommended that mesh plate vales are run much more conservatively, say below 25W dissipation for long life. Having said that they worked very well in the SJS Model 5 power amp at 30W dissipation.
