 Dynaco ST70 rebuilt with Welborne Labs Driver board mod. This amp is in great condition,,The driver tubes are a pair of GE JAN 5751 And splitters are a pair of Philips JAN 6u8a in mint condition very low hours on all these tubes.this unit gets rid of the quad cap and uses much better Mallory Caps that are placed into chassis on the welborne labs board with More capacitance for much tighter deeper bass. I will also include the Sylvania fat bottle 5ar4 which is one of the best 5ar4 available,No EL34 tubes are included with the amp.
