This trusty beast has been to battle with me many a time, but for the past year, it's been retired to my backups case, so it deserves a new home.
This is a Decimator 2 - SDI to Composite downconverter, and SDI to HDMI cross-converter. Never needed to be serviced, never blown up. There are a few scratches and dings, and some of the lettering has worn off, but it worked perfectly the last time I needed it. Keep a backup for using your TB-6 CRT, or use it to turn an HDMI LCD into an SDI monitor (what this was often used for).
Comes with the original AC adaptor, and I can toss in a homemade GPI PRO 4 pin LEMO to Decimator Power/Video cable for an extra $50.
Paid $500 in 2011. Asking $200 without the LEMO cable, $250 with. Email me at firstname.lastname@example.org.
