xlr8or Posted October 25, 2022 Share Posted October 25, 2022 (edited) Just a quick update from me on my 7th Japanese made tube amp, The front end EF37A's are driving the 300B's very nicely using a 5U3C (5U4G) rectifier. There is plenty of peak to peak drive available for the 300B's to shine. Love this sound .... Edited October 25, 2022 by xlr8or 3 4 Link to comment Share on other sites More sharing options...
