I picked up an additional ST-70 a few days ago. When I arrived at the sellers home, he had it playing some music and I thought it sounded just fine. I pulled the screws, three to a side, and took a quick look inside (cant be to careful) everything looked in order and I noted it had cloth transformer leads. Today I had it set up in my workshop and I noticed the transformers were both marked: 454326 and Z-326 the power transformer was marked: PA 060. So here is my question. I thought only the A-470 transformers had cloth leads and I thought the Chassis with three screws were newer moldels. Is it reasonable to assume that this was a transition piece where they ran out of the A-470 covers and just slapped Z-326 covers on the older cloth lead wound core?
Can any of you hard core Dynaco historians shed some light on this ?
As always thanks for your knowledge and support!!!!
