This is my enhanced Teaberry T Command service manual. I also included the usual separate spliced together schematic. This schematic is not a redraw like I sometimes like to do with radios that I own, but nevertheless, it should be easy to follow on the big screen.
I suggest Celine Dion singing "Hymne A L'Amour" at the base of the Eiffel Tower following the cauldron lighting, but youtube didn’t allow linkage. If you haven't seen this spectacular performance already, view it on youtube or other sources directly.
There was a time when I was burning mini CD-R disks. I wanted to try something different, but my interest didn’t last long. I must say they were more convenient to ship. I remember that I always had to make sure the mini was removed before a full sized disk was placed in the tray. Otherwise...
I did a redraw of the Robyn T-123B. I also corrected several tube pin-out errors. Hopefully I didn’t create any errors of my own in the process. The “Green bird” once saturated the market in our area, viewed especially as an alternative for those that couldn’t afford a Tram or Browning. Usually...
The 77-830 is my pick, only because love the old Cybernet circuit boards. The 510XL does have better transmit audio, because they use a different type of mic (Electret condenser) that has a wider audio range. The more common dynamic mics used on many other radios will not work. I do a number...
I know it’s aggravating, but Sam’s (except for some of the early radios) negated to list the resistors in their parts pages. It has become a two step process. Download the CB-243 Cobra 87gtl pdf file that Shummy posted. The resistors in question will be either on page 14 or 15. Study the...
Hachi A Dog's Tail
This one brought tears even after seeing it for the second time. As kid, did you cry after watching Old Yeller? If you love dogs, Hachi is sure to bring a tear at any age.
This is my Lafayette Comstat 25B schematic that was redrawn for my archive and others that might be interested in restoring this classic. The original schematic that was posted previously needed clarification with a higher resolution and additional detail.
I have an old 2 meter Regency with a weak front end. A pre-amp brought it back to life. Stations down in the mud wouldn’t be heard without it. A particular receiver’s sensitivity is a huge factor in determining whether a pre-amp is needed or not. Without knowing how sensitive that particular...
The very early Sam’s never included a block diagram. Book 14 contains 14 radios, all with a limited number of pages.
The Comstat 19 uses the old HC6/u crystals. The transmit crystal operates on the operating frequency and the receive crystal operates at -455Kc from the fundamental. As an...
That was the best C.W. McCall logo pic I’ve seen. I agree, that one needed to be saved and enhanced for future use as a poster or smaller accent in an old school shack. That logo was placed on a number of different Midland models during that time period. I decided to delete the reference to any...
The 02A will give you lows all the way down to 26.645Mhz with no missing frequencies in 10Kc steps, provided that you also program the 10KC pin 15. No extra mixing crystals are needed. In my experience it will go down even lower, but radical re-tuning is required that would also affect the...
Back in the 80’s computers mainly used gold plated jumpers. I had a bag full of jumpers, but I now have a much smaller amount since I tossed all the others.
I consolidated your Zip into a single modified PDF. As usual I spliced together the schematic, and put it in a separate Jpg file. The high resolution of your original scans were great, but the circuit boards would have turned out a little clearer if they were scanned in at least 256 grayscale...
A short time ago in the midst of Covid, some people started raising chicken in their garage, just like they did in during the great depression. People stole ketchup out of restaurants to make tomato soup for their families. People jumped out of high rise windows. So much for the stock market…...
Our short haired bully sheds a lot too. Breeders trick: Disposable gloves help collect that hair. Dogs love a rub down and most of the hair will attach to the glove from the static it produces. Hairs along with the gloves are then tossed in the trash afterwards. A win win....Just another tool...
