    TELEX CB-73 Microphone

    Well I finally got her going. It took quite a bit of "unmodifying". Two buttons were removed that were added for some weird switching as well as random resistors soldered all over the place that looked like everything was added by a three year old! Now back to original factory wiring. Thanks to...

    TELEX CB-73 Microphone

    Thanks for that! I will dig into this over the next day or so and let you know how I make out. I think I should be able to piece it back together with the help of these pics. Thanks again!!! 73 Tom KCINGR

    TELEX CB-73 Microphone

    That would be great!!! Sorry it's taken so long to get back to you but it's like to get this mic going if possible. Any pictures of the board would be greatly appreciated!

    Kobitone microphone element(Part #25LM022) comparison!

    Hmmm I have a good assortment of hermetically sealed Korbitone elements which I have experimented with. All pretty good but I have to say that their is a noticeable difference in total tonal properties when comparing a nice sounding MC320 against most of my Korbitone heads. Sorry dude, just...

    Kobitone microphone element(Part #25LM022) comparison!

    Maybe, or maybe just the care taken 30+ years ago with manufacturing a pristine quality crystal head microphone. Astatic just made good shit back in the day, plain and simple. It wasn't the size of the head, it was the quality control and the hand picking of organically found Rochelle salt...

    Kobitone microphone element(Part #25LM022) comparison!

    Of course the original MC320 element in good condition (minus being stored in an otherwise less than perfect humidity/temperature condition) is untouchable in my opinion, the Korbitone element is the absolute best replacement for authentic audio properties, and taken into account it's almost...

    TELEX CB-73 Microphone

    Thank you for that! That helps with getting the mic wired correctly. I'm hoping that someone may have the board schematic, showing component layout as well. This thing has been hacked good lol.

    TELEX CB-73 Microphone

    This thread is a bit old but I picked up one of these Telex CB-73 mics and I am trying to get it back to factory. Whoever had this before hacked it with some strange mod that has two pushbuttons on the top of the mic. There's also added resistors on the mic switch which I'm still trying to...

    Sirio 827 base antennae issue

    So it's been awhile since the last post on this situation. Well I'm convinced it's just that Texas Star is now total crap. Steer clear of these amps as they are now total crap. I have alot of respect for Mike and I know he knows these amps but he is in denial just as Texas Star is as a company...

    Browning Mark 3 receiver drift fix.

    Just a quick update on the state of this repair. What I ended up finding was that my major drifting issue was with the main tuning dial itself. Just years of oxidation that took a lot more elbow grease with a fine burnishing stick and some D5 cleaning the contacts at the capacitor shaft as you...

    Browning Mark 3 receiver drift fix.

    I can tune that frequency in on my old Yaesu FT101 receiver. I will test the mechanical oscillator link tonight using that method. Thanks for that. I am also not 100% sure now if my new C50 trimmer replacement that I put in at the beginning of this whole thing was actually bad from the get go. I...

    Browning Mark 3 receiver drift fix.

    I haven't noticed any particular skittishness in the tuning dial itself but I will certainly give it a real good cleaning this evening. I've gotten myself some white nylon string from the hardware store this morning and I have some 99% Isopropyl so we'll see if it helps or not. Maybe some D5...

    Browning Mark 3 receiver drift fix.

    Well, it appears that I raised the victory flag too soon. The drifting reciever is back at it. Uhhg!! It seemed to hold frequency for a couple of rag chewing sessions and then it started jumping around again this afternoon. At this point I'm hoping Nomad has the capacity to take this girl in for...

    Browning Mark 3 receiver drift fix.

    Sorry it took so long to report back but here it is. I completed Nomads mod and, holy crap, my bird once again can hear!!! Thank you Chris from the bottom of my heart. You are the man!! After carefully completing the mod and making sure that my 5V signal wire was not causing stray capacitance...

    Browning Mark 3 receiver drift fix.

    Excellent. I will complete the mod this evening after work and report back the results. BTW my Mark 3 does not have the black wire attached to SW2 and it does not appear that anything else had ever been soldered to the open lugs of SW2. That being said, my dial light has never shut off when...
