Checking the ETF site and scrolling down their 19" color page, pictures both a Raytheon and an identical rebadged Trutone 19" with the CBS 19VP22 tube, both with links to an ad. Click the link to the Raytheon ad and it shows the set with the 19TP22? tube. The set now in question on this thread with the more stylized cabinet. Just adds to the mystery.
