The power amplifier we supplied was an Insight+ Double 170 built in a Dyna St-120 chassis.
I had expected to have an Insight+ 240 available in our own chassis for the event, but my demo unit, sent out for an evaluation ended up being sold and not returned.
The Insight+170 has the same audio circuits as the 240, just a slightly smaller power transformer to fit in the available space and a different layout.
When we rebuild an old Dyna St-120, all we save is the bare chassis, cover, two of the black metal heat sinks, and the black and red binding posts. Everything else is brand new. Its a fun project for us to build.
I am very glad our equipment worked well for you and with all those different speakers. It appears a great time was had by all.
Best regards,
Frank Van Alstine
