Al et al.....
Those of us to whom changing final transistors has become routine, often
overlook a small but crucial point when explaining to others just how to
go about doing it.
After you've removed the old transistors, clean the pads well and make
sure the sink surface is clean. Then, after applying compound to the
transistors, mount them and tighten the screws BEFORE SOLDERING the wings.
If you solder before tightening the screws, you'll likely pop the metal
sink off the backside of the transistor, and that cannot be repaired.
So, if you're a fan of MP devices, neither of your new transistors are
useable and you'll need a new matched pair.
Other than that, it's pretty simple. You shouldn't be afraid to tackle
it yourself.

and the whole crew to be Very Helpful. Once you become accustomed to the
way Ten Tec lays out their schematics and learn some of the common problems
.... they are a Joy to work on.
Final Replacement ....?? 1. Remove old Finals 2. Replace with new ones.
Make sure that all soldering is done neatly using enough heat. Some care is
needed here, there is a fine line between enough heat and too much. 3.
Check and adjust Bias if needed and neatly reassemble the radio, paying
close attention to connectors and the placement of cables. I know of
nothing more that has to be tuned or aligned. If, I had a full Lab Bench I
would probably check things out a lot closer. My equipment is the good
stuff but, very old. Thanks to John Henry, Paul and Gary... and the entire
Ten Tec Staff for their support.

Thanks for the support of TenTec SERVICE.

6 months ago I tried to have finals replaced in my Delta-II; Service told
me it was not worth to do it.
===============
That should be a decision the the owner should make. They would not give
me an estimate of repair.
I wasted the $$ for shipping both ways and the normal fee for the bench.
I'm still trying to find someone to replace the finals. Maybe,
Instructions from the factory could be made available for the owner to do.
All the advertisement about service didn't come thru for me this time.
I have had good service from Paul & Gary in the past.

TEN-TEC does have an opening for a service tech, and the main rig that
service tech worked on is the Orion models. So, if anyone nearby wants to
apply, get with Paul Clinton in service and see what happens.
Depending upon the nature of the problem it might affect service turn
around, but, we are having production techs handle servicing at the moment
and also one of the Orion engineers is handling the more difficult repairs.
On average though, they get out rigs per week as fast as when we had a
dedicated service repair person.
I think what really impacted service times on the Orion is the changes in
the latest firmware revision. The latest software releases provide features
that improved the performance to a point that people are hauling out their
Orion's out of the closet and placing them back on the bench as the main
transceiver again. We are running into a lot of rigs that were "mothballed"
and for whatever reason now have some issues. So we are getting bombarded
with a LOT of rigs whose problems would have been resolved over years, now
all at once. I guess that is a problem with continuing on with software
updates providing new features taking them to new performance levels,
1 - we don't sell new rigs (why buy a new rig when the performance level of
the Orions are now jumping ahead of competition? SAF for example, best
feature added (per several customers inputs) to any rig in years)
2 - we have to service more rigs. (rigs that were put in storage, off the
shelf, and due to whatever reason now exhibit issues that need repair).
I'll quit rambling and get back to work. Enjoy
Thanks, and 73,
