Dynaco ST-70 Audition with FM-3 tuner

Dynaco st-70 I modded, has the tubes4hifi vta hi-gain board with upgraded russian pio caps and upgraded lytics soldered under board, 4 bias test points in front. Runs a SDS first gen cap board underneath, mullard rectifier with 4 new jj el34’s biased at .4v each. FM-3 tuner has the cap board and pec boards on order from SDS but it works as is!
