[TenTec] Looking for photograph/sketch of assembled Ten-Tec MR-1

[Bwana Bob]

Maybe Ten Tec has the documentation. While some old manuals are on their 
download area, they don't have everything there. A inquiry may bring you 
a copy or maybe Ten Tec will post it on the download area.

The VO1 capacitor rotates only 180 degrees, so if the calibration marks 
cover only  half of the  dial area, then it was meant to mount on the 
capacitor shaft. Also, look at the dial to see if it has a bushing and 
setscrew to mount it to the capacitor shaft. If, instead, it has two 
small holes on either side of the center hole, and the calibration scale 
covers most of the dial area, then it was probably meant to mount on one 
of those 6:1 vernier drives. I doubt that Ten Tec intended the MR1 to be 
used with a dial cord. That would introduce too many variables and 
complexities.

                                 73,

Consider a large wood file card box, wood gift box, surplus ammo box Pelican case, sportsman's dry box, etc. If you do breadboard it, as in the days of old, you will still have to mount the boards on spacers and fabricate brackets to hold the variable capacitors and switches. You will also need a vernier dial drive because the VO1 tuning capacitor does not have a reduction gear, at least mine doesn't.
