Banbury

Looking for some insight into an old Japanese build amp and its applicability to being used with GB mic. Its Teisco Melody using 6AU6 drivers and 6RA5 outputs with a small 6 inch speaker. Very little info on the web, and a total nob on these tubes. I won’t have a chance to test this item out before purchasing due to meeting the owner some several hours drive at a Ti1#&ym82m7;s.
