My Eico 710 GDO has died. No response to changing coils. Dial light comes on when turned on. I have found a users manual but not the building manual. Does anyone have assembly or disassembly instruct

My guess would include a failed tube, probably a 6AF4 UHF tuner triode, or a broken cable if the power supply is separate from the dipper. Getting into the dipper probably requires removing the screw

Jerry, I suspect the tube myself. I have the case off. The GDO is in a subchassis and I started to take it apart but figured if I could find the construction manual, I might save myself some grief. I

The world is starting to look a lot better. I bought a tube from http://www.vacuumtubes.net and I received the tube 2 days later. Installed the tube and got a meter reading. phew! I now have new issu

That brown stuff is probably Pliobond. A rubbery contact adhesive. It holds better than tape. It may still be available, if not go to a car parts store and get a tube of 3M trim adhesive. 73, Jerry,

Jerry. Thanks for the tips. I have a trip to the hardware store in my future. My GDO lives again. I also feel better about my knight-kit tube tester that has a place of honor on the shelf in my shop.

A grid to cathode short was the most common failure for the 6AF4 family. It had tiny geometry and small spacings to oscillate up to about 850 MHz in the UHF tuner or converter. And short life from th

John, If there is room for the tape, I have used tape to glue a plastic window, and it worked very well, and held up. Use good quality tape like 3M, not import Dollar store stuff. -Stuart Rohre K5KVH

The tape I used was the Scotch 3M Magic Tape, cause that was on the reel at hand. Seems to hold up well, and is a bit thicker than import clear tapes. Stuart _________________________________________
