Sorry, it won't work. the 8YP4 is magnetic deflection while the 7JP4 is electrostatic. The sockets are different too. I use a 7VP1 for testing. It's a green phosphor CRT I pulled from an old o-scope. jr_tech 12-12-2009, 09:37 PM That sounds like a great idea :thmbsp: What model 'scope did you yank the 7VP1 out of ? jr bandersen 12-12-2009, 09:59 PM That sounds like a great idea :thmbsp: What model 'scope did you yank the 7VP1 out of ? jr I pulled it from an RCA WO-56A. I wonder if other scope CRTs might work as well - like a 5UP1 :scratch2: http://farm3.static.flickr.com/2657/4180695108_4508948d9a.jpg http://www.bobandersen.com/images/TS4H/s020.jpg |
