Hello to the group.

Well, I had time today to do the PTO rebuild. As one gent said, 
"The first one took about 2 hours". That's about how 
long it took me from start to finish. Everything you need to do the 
job is in the parts kit from Ten Tec.  Now I no longer have warbles 
in my audio when tuning someone in.  The only negative things I have 
to mention concern the written directions for the kit. Step one says 
"Remove the PTO box from the rig". No mention of how to go about this 
onerous task at all. I have been an electronics tech for about 30 
years now, so I didn't have a whole lot of trouble identifying the 
PTO. For the less technically inclined, a little more description of 
how to remove the PTO would be in order. One step you need to perform 
is not mentioned in the write up at all. To disassemble the PTO for 
rebuild, you have to remove the top cover of the PTO box!! I am a real 
stickler when it comes to following directions, and when it came time to 
start removing parts, I couldn't even locate them due to the cover still 
being in place. 

Try and have a helper around when you install the kit! Some of the steps 
are much easier to perform with 2 people. Besides, it givves you someone 
to talk to while you are doing the job. Lastly, read the directions a few times 
while studying the diagram supplied with the kit. If you understand what it 
is you are about to tackle, it makes it a whole lot easier.

To remove the PTO from the rig:
Remove the tuning knob as described in the Corsair II owners manual.
Behind the tuning dial skirt you will see 2 screws. Loosen both 
screws, but DO NOT REMOVE them. These two screws have a kind of 
safety pin attached and are a real bear to get back in place if 
removed (experience from today). As the screws come loose, hold onto 
the PTO box so it doesn't drop. 

Good luck to those of you that are about to start this process. It is 
not all that hard to do, and well worth the effort. Thanks to all of 
you who were kind enough to email me with things to watch out for.
