Hi to all,
@Wayne B. you're surely in the true about the mechanism which destroyed the Barco's flyback and H out transistors. Our lab guys weren't too interested in the inner workings of monitors, they just made sure the info got around "don't use the Barco(s) without Sync !"
BTW, i made a mistake, it was the 22" or possibly the 25" model which failed. These were carted around standalone for demos or customer training and not nicely wired in a permanent rack.
H out transistors were pricey in the 80s, ouch !
Glad you liked the French magazine !
a group of guys of our forum is scanning back issues. Like the UK mag "Wireless World" it ran from the 30s to 2000, so the database is huge. They proceed by sampling interesting issues in each era. Publication is +/- one every week, see here, 43 page long topic, everything is in pdf so downloadable :

@Kf4rca, yes the VPR-80 came with a CTVM22 9" monitor "side-car" style.
On the VPR-1/1C/2/2B/VPR3 & the Quads (AVR2/AVR3) having a bridge monitor we used the Tektronix 12" Trinitron monitor, then later Trinitron HR.
When i worked at RCA (summer jobs) there was a 12" Conrac, also with Trinitron tube. I got a write-off for a song, fixed it & still have it in the
attic...
@TeleColor3007 : you asked "I wonder what cameras French colour television used in it's early days."
You must define "early days" : 1)Monochrome
30s : Barthelemy mechanical design, CDC (Compagnie Des Compteurs), 30/60/120/180 lines
Mid-end 30s : experimental Iconoscope, (US import), Telefunken licensed Iconoscope, Radio-Industrie cameras.
Mid-end 40s, same as prewar, then CFTH (Compagnie Française Thomson-Houston), then Thomson-CSF. Thomson reigned supreme as a French supplier & state-controlled TV.
2)Color :
Thomson ruled the roost from 1950 to the 80s, then Japanese cameras took over (Sony, Ikegami) via U-Matic news reporting, then Betacam.
From the Jo Flaherty, head of engineering at CBS + Sony venture came the MicroCam, a truely miniaturized ENG camera. Thomson made some improvements and it became a popular product.
RCA (TK-76) was also very popular for ENG. Later, the Philips LDK-14 & Ikegami HL-79. Still later, Sony BVP-300/330.
Before CCDs, camera tubes (Orthicon, Image-Orthicon) were of RCA US construction & later manufactured under license by Thomson & EEV (UK).
Philips made huge inroads with the Plumbicon tubes for color pickup.
Later on, Japanese Saticons, Newvicons were also offered as options in new cameras.
