It took me three hours. The parts in mine were worn so the rebuild kit
was a necessity. Work over a tray with turned up edges (like a cafeteria
tray) and no gaps, else you will be in need of small steel balls.

Its the external PA control relay. Many have been quieted with a match
stick or piece off a match book between the clapper and the coil.

While looking for a complete manual, does anyone have page 3-34 in their
manual. The manuals that WA3MKB and I have, two that came with radios,
one from W7FG are all missing page 3-34 which the table on contents says
is the parts list. Is this a page Tentec neglected to update and so
ripped out, or is it gone because its the last page of the book?
