Hi Group,
For sometime I have considered having wood side panel replacements made for the
Triton transceivers. I have made drawings for the replacements
and have a CNC shop that can do the work. Also, mounting screws would be
machine screws and not tapered wood or metal screws. This will facilitate
opening the unit up for repairs with no concern of stripping anything. I don't
have a final price but would like to see the cost be around $50 give or take,
If I have these made, I will sell them to users of this reflector at my cost
plus shipping for 30 days and then sell them elsewhere at a higher price.
I am considering Oak but other woods can be used. There are some exotic
hardwood that are beautiful but also more expensive. My CNC guy does not care
but he wants to work with one wood type at a time to keep his human
intervention efforts minimal.
The Triton IV's had the aluminium, non painted front panels and many have
oxidized or have rub marks, not to mention scratches, mod holes and other
damages. I may additionally look into having new panels made and screened. My
cost to have these done will be near $50 each as well. The screening alone is
right at $20 unless the screen shop can screen multiple panels at the same
time.
The Triton IV's, although, not as good as a Corsair, are decent transceivers
and with a cosmetic face lift might well be a great companion to a Corsair or
Omni ?? rig.
Some of the Triton IV's will need lots of work such as band switch wafers
replaced, solder connections redone and old caps replaced. Clearly not
something that would be cost effective to have done, however, many of the users
of this group are technically minded and enjoy tinkering. This is one of those
labor of love projects that could be loads of fun and yielding a nice looking
Rig. Personally, I like the look of Hawaiian Koa but the cost of the wood might
exceed the cost of the Triton; but it's cute!
So, is there interest or what are your thoughts?
Regards,

Hi Barry,
Thanks for the encouragement. Perhaps this will be a good winter project.
It would be awesome if I could talk Jerry into doing the board layout.
The design work is finished and I wish you could hear the audio from my Cosair
II with the
Bur Brown OP amps; it's sharp, crisp and clear. IF you have ever listened to a
Racal 6790GM on SSB, I would rate the
audio even better. Compared to a regular Corsair audio stage it's literally
night and day difference.
What I would need to do is verify my notes and schematic and see if Jerry could
be persuaded to do the layout. This is an area
that I am slow in and based on the SUPERB job he did with the layout of the
display board, I am convinced he could do the work very well.
Keep in mind also, I have between 30 to 50 of all 21 IC's on the Omni 6 logic
board. Several of these IC's are not available at Digikey, Mouser, Allied,
Newark nor Jameco. I found an overseas company who probably has the worlds
largest NOS IC Inventory.
Since I don't have permission yet from Ten Tec, I will not burn the 27C64 and
27C256 EPROMS. However, I do have about 60 of each in stock if anyone wanted to
burn a spare set for their own consumption.
I know Ten Tec does have and sell those EPROMS should anyone need them.
On the boards I repair for clients, I install machined IC sockets wherever I
remove a defective IC. I have 3 logic boards that I have installed machined IC
sockets
in all 23 positions. These are my test bed boards.
On my test bed, I stack machined sockets to raise an IC above the clutter of
cables and connectors on the board. Then I install my custom ZIF, Zero
Insertion
Sockets, for troubleshooting. As an example, I can raise U1 and clamp on my
custom 40 pin adapter that goes to my Logic analyzer. Then I can exercise the
encoders and front panel switches to look at at the buses for faults.
As it turns out the pins on a ZIF socket are designed to be soldered to a board
and are to wide to fit into a machined socket. Even too wide to fit into a leaf
socket. So, I developed a technique to hand solder all of the ZIF pins to the
top side of a machined socket. Once I developed this technique, it was not to
bad to make even 40 pin mates. Now the ZIF will plug into a machined socket on
the board or I can raise it up by stacking sockets if I need more room.
Remember
ZIF's are wider and longer than sockets by a considerable amount.

Glenn, I can't encourage you enough to proceed with the AF/IF project.
Lately my focus has been on the AF side and I drifted from the Corsair
II to the Omni 6. The AF strips in both radios are throw-away and I'm
in the midst of replacing everything in the Omni 6 except for the dsp
sidetone (everything else in the dsp + notch + af output goes). It is
just amazing when you unlock the potential in these radios that was
hidden/mangled by bad AF circuitry.
