[R-390] OT: Tubes needed for TEK561A

[Scott, Barry (Clyde B)]

Dennis,

I'll probably have to join that group (if they'll have me).

This group, though, is pretty amazing.  Within 45 minutes of posting, I have
two businesses with the tubes for $8 each as well as some "I have some tubes
I'd be glad to send you".

My initial search turned up some of the more expensive European brands at
$20+ each and that's what I was trying to avoid.

Thanks guys!

Hi Barry (III),

	If you haven't found it already, you might try the "TekScopes" list 
on Yahoogroups.  There are some true experts hanging out there.  I 
have a 545A and a 531...but no spare tubes.  Luckily, I haven't 
needed them yet.  These scopes just keep going, and going, and 
going.....

	Good luck...pass on any sources you might dig up.
