Used to have a picture of a blower mod one of my customers did to his Pride. Found that a plastic caulk-gun tube was a near-perfect fit for the old blower's metal flange. It was tall enough to protrude through a hole in the top of the cabinet cover. A blower with a 2-inch round flange was bolted to the top of the cabinet and used the caulk tube as a duct.

Looked quite odd, but did the job. Made it a PITA to take apart and reassemble.

More air is always good, especially if you go for the 8930 type tube. Had a guy tell me years ago that too much air is not desirable. Found the quote in Eimac's book "Care and Feeding of Power Grid Tubes". Airflow is only excessive if it dislodges the tube from the socket.

We use a Dayton 1TDN1 or equivalent. Has just enough capacity for the stock 250 tube and fits without an act of congress.

[QUOTE="nomadradio, post: 855134, member: 22"] Used to have a picture of a blower mod one of my customers did to his Pride.

A blower with a 2-inch round flange was bolted to the top of the cabinet and used the caulk tube as a duct. Looked quite odd, but did the job. Made it a PITA to take apart and reassemble. More air is always good, especially if you go for the 8930 type tube. Had a guy tell me years ago that too much air is not desirable.
