How can I search for 604-8H or 604-8E ?

[tubestyle]

I’m trying to find a way to search for threads that discuss the 604-8H and the 8-E. How can I use the search engine to find the threads?
I tried different ways, but I’m sure i’m not getting all the threads.

Thanks

Go to search
then advanced search
enter Altec 604 and titles only
expand your search by adding posts

Here's one of my faves

Thanks Cal

I’m trying to find info/comments on the GPA 604-8E, and the MLTL with the 604 in general.

A search with 604-8H or 694-8E doesn’t return anything. A search with GPA and a combination of 604 does not work either. I think there is a limitation in word size. Looking for Great plains audio does not include all the posts with GPA
Altec works, but I’m not sure I get all the hits I would like to see.
