Good news update to the "band-aid" remedy of a fan to reduce processor temperature: For what it's worth, the installation of a 30mm x 30mm x 10mm, 12v, 1.8cfm fan to move a little air thru the logic
Mike, Thanks! Pulled the P22 plug (schematically labeled "KEY/GND", and the processor keyer output is disabled, AND I still have straight key/bug CW capability. I can sure live with that. 73! Allen--
Of my two Corsair II's, one has a NB board p/n 80977, which correspond to the NB called out in the manual. The other Corsair II has a NB board p/n 81401, for which I've not been able to find any docu
Yes, the circuitry is different. The 81401 IC complement is 2-MC1350P's and 1-LM358N, and it has 6 transistors and 3 diodes. Interface to the NB level and NB width pots (connectors #7 and 22 respecti
I agree. The NB on the Triton's completely eliminates my S9+ powerline noise, but neither the Corsair or OMNI V NB's are effective dealing with that noise. I too have wondered why the Triton NB desig
With my particular noise source (powerline), the TRITON NB removes the noise without having to fuss with anything, and at least I cannot detect any compromise of audio quality. The ANC-4 that I use f
I've run across two 425's, each with different front panel color schemes and knob styles. fine-serrated tune and load knobs, and no 10m legend marked on the panel. Front panel is marked "TITAN" (no 4
Thanks Barry. That link was really useful. It looks like the #1 amp in question is the third production variant described on the ref link. Owner says the nameplate specifies Model 425, s/n 91A10160.
I believe they're Chinese mfg branded "TAYLOR". Can't speak to their life or reliability. 3CX800A7's are cheaper than I remember. When I blew up the ones in my Titan through grievous operator error,
Does anyone know of a source for a suitable replacement for the 60 microHenry plate choke for a TITAN 425? The guys at Sevierville can't help. Thanks.... _____________________________________________
Thanks to all for the leads and suggestions. My first thought was to rewind the damaged choke, since the core/form is still good. Actually, although the choke has obviously been overheated and I can
I ordered one this morning online, and am just waiting for the shipping cost quote to finalize the order processing. We just put one of these chokes in an Alpha 76A and it works fine. I think the pri
I've completed at least the initial resurrection of a long dormant, and neglected (abused?) 425, and have a question re what the resting current (keyed, no signal) of healthy 3CX800's should be in a
Does anyone have any "spare" pushbuttons for an OMNI V or OMNI VI? I have a need for the "REV", "A=B" and "A/B" pushbuttons. Checked with TT, and they can't help. The silk-screened legend/characters
Recently acquired a nice OMNI VI Plus-OPT 3, and have disposed of all issues except for an inop VOX function. In fact, the VOX misbehaves. When the VOX pushbutton is pressed, I get the VOX lamp lit,
Dave, My OMNI V is I think an '89 production (s/n 63A10699), and like yours has the 8-pin U8 RAM. The hold-up battery is an easily replaceable 3v CR2032 Lithium which I replaced about 2 years ago whe
My recently acquired ORION 565 is one great radio, but has one annoying trait. Upon power-up, the panel-mounted VFO A encoder ignores rotational travel over about a 180 degree arc. The dead area of a
Mike and Barry: Yikes! No "MULTI" control would be a definite PITA. Given the symptoms, the connector interface integrity sure makes a whole lot more sense than a problem with the encoder itself. I'm
Does anyone have a Studio One mic with a 4-pin mic connector-equipped cable available? Looking to replace the 705 currently on my 565 Orion. Please contact me off list. Thanks and 73, Allen--W7GIF __
DigiKey definitely has them. Their p/n 497-3689-5-ND is the 48mah, 497-3690-5-ND is the 120mah. The 120mah SNAPHAT fits/works well in the 565 Orion. 73, Allen--W7GIF -- Original Message -- From: Scot
