Hi gonzo, Im just getting into my mach one mod. I'm wondering what you decided to do about the vents in the horn driver body? Did you just leave them open? When I asked AI it told me to cover them with plumbers putty....But it seems that steve just left them open? Wondering what you did and how it worked out. Thanks

Good morning, Dony. Started going thru your check list this am, and got as far as step 9, and I'm stuck. Just to verify, I have an Hp model s5603w desktop. I'm not getting the allerts on a watched item that I should get, but will watch for a reply. Here is a pic of the screen I'm on.

Looking to buy the "STK-0050-II,60,70,80 replacement Modules(2), complete kit with all parts & docs" off eBay, but there is a no ship to Maryland, US issue. I messaged you about it. Do you sell here? I can do PayPal or Venmo.

I have a Fisher SA 880 I can't seem to part with that needs "restoring".

Thanks again!
