OK!  that makes sense!
 
I have heard   about the deck tipping but have not tried  thanks  for the 
warning!

Just catching up on posts. Did not  mean to imply that adding a hi-band 
head to a lo-band machine would constitute  the complete conversion, it's just 
one step. However, doing this on a TR-5 did  make the editors more pleased 
with the quality of video brought back from  remotes.
 
Hi-banding was an expensive operation for a small station in the 70's. We  
had moderate success hi-banding (playback only!) a couple well-used  TR-22's 
by following a homebrew procedure given to us by some helpful folks at  a 
Kaiser Broadcasting station in Detroit, where the non-RCA conversion was  
probably designed. Widening out the bandwidth of the RF stages was a big part  
of the process.
 
One safety note for anyone working on a TR-5. The deck will raise up  about 
10 inches in the back, making it easier to slap those heavy 60 min reels  
of tape on the machine. There is a potential guillotine hazard if fingers get 
 caught between the underside of the raised deck and the machine's side 
panels;  and the deck drops unexpectedly. A single pair of telescoping square 
metal  tubes with a pushbutton latch are all that supports the raised deck. I 
drilled  a hole in the lower tube and put a #10 bolt through it whenever 
the deck was  raised, which was 95% of the time.
 
The machine in the color photo looks very clean, like it had seldom been  
on the road. Just hook the video out to an old monochrome Conrac monitor with 
 a decent sync separator and playback will be fine for a museum. Consider  
showing off the unit with monochrome video in LBM mode, to get away from the 
 fuzzy appearance of color, due to the lesser-deviated LBC mode and 
dot-crawl  issues.
