Hello!
Thanks for checking in - yes I get e-mails about the step-ups almost every day.
Both the pre-amp stuff and the step-up are very close to a resolution - I am deep in step-up testing this week. I'll be posting a complete update of all the products and the results of my testing early next week. That'll be followed by a web page update.
Despite the fact it has been slow at the forum I think August was close to a record months for shipments - much of it cleaning up old stock along with some resistor based units, lots of remote control kits, etc.
Sorry to not have more updates or to have new products flowing sooner - I was determined when I started this new stuff to take time to get it right!
Thanks!
John
