Re: Disintegrating Handle on my TM503
Hmmmm¡­ Seems like cold-shrink tape may come to the rescue. Made by Daburn Industries and Available from Digi-Key and maybe Mouser. Put some foam or bubble wrap around the metal handle and then

Look for heater hose at an automotive parts place. This one is not Tek blue but close: https://radiatorpros.com/catalog/product/view/id/5354?gad_source=1&gbraid=0AAAAACfza3oIShxzph-nbtZ-58F5q7bXo

You might consider a length of garden hose or the equivalent for an inexpensive replacement. Harvey

Re: Disintegrating Handle on my TM503
Hi Benjamin. I personally have not had any success restoring old tektronix handles. However there are a lot of companies who make equipment handles. Ones intended for audio equipment usually will work

Re: Disintegrating Handle on my TM503
Not with a tm503 yet, but most 5xx scopes. A method I like is wrap with leather and sew shut. I might have some spare tek blue handle material from other cases. Would need to be cut down

Disintegrating Handle on my TM503
Hello people of TekScopes, I have a TM503 with a disintegrating handle. The blue outer sheath for the steel inner core has become brittle and ripped open. This just leaves the thin strip of rusty

Re: SC504 Trace Shadow
Edward, First off thanks for your comment. This scope has other issues right now. I need to understand more about crt acceleration. But will go through a full calibration if I can get everything

Re: SC504 Trace Shadow
Ozan, I took both of the hybrids out for inspection. I found an open trace on Pin1 and Pin2 of the hybrid that was installed on channel 2. I tried to repair the trace but ended up damaging several

Re: SC504 Trace Shadow
I see some type of conic beam expansion going on. The gost image is larger in both the x and y direction. Guessing it's crt (acceleration) related. I would check every bias voltage going to the tube,

Re: SC504 Trace Shadow
Hi Barry, If you look at hybrid schematic on TekWiki pin 1 is the mid point of a 845-ohm to ground and 1.21k to +5V. In your measurement Ch2 hybrid shows ~ 0.366-0.649V at pin 1. This means a current

Alternative calibration pulsers for the Tek 11801 family.
I was going to attach screenshots from my 11801/SD-32 comparing one of Leo Bodnar's new LBE-1322 pulsers to the calibrator in the 11801. Seems I'm not allowed to do that. Don't know why or care.
