: : : : : : : : : : : :Sir Bill. . . . : : : :Ahhhhhhhhhh Soooooooooo . . . . with your most honnable info . . .and evaluating it, seems like you just might have have found yourself what is called a :a piston variable capacitor. : : :BUT the SAMS page 3 photo is too poor for me to be able to differentiate it out in the possible area it is used . . . near osc coil L4, possibly as capacitor adjustment A7. It possibly might even be a glass cylinder with L4 being a spiraled flat ribbon wire wound around it, for its required 2 or 3 turns of created inductance. : : :The metal piston "slug" will be internal of the glass tubing and is adjusted with a threaded screw which drives it laterally. : : :Can you get a digital closeup photo for confirmation ? : : :Also that sel rectifier should be your low B+ problem and needs a 1N4007 silicon diode totally replacing it. . . . no mo' SR. : : :Also filters may be in order after 50 years of time. : : :Your volume and performance should come up appreciably after that. : : :A 1N4007's increased B+ output will require some raising of R22's ohmic value to set the B+ back down to its initial value with the old SR being initially used. : : : : : :73's de Edd : : : : : :Why Athletes Can’t Have Regular Jobs: : : : : : :Upon his hearing of Joe Jacobi of the Redskin’s say: : : :“I’d run over my own mother to win the Super Bowl,” : : :Matt Millen of the Raiders said: “To win, I’d run over Joe’s Mom, too.” : : : : : : : :

::::::::::What is the difference between models 610 and 610U ?
::::::::::
::::::::::I can provide the Photofact for model 610 (six tube FM only tabletop)however I can find no documentaion for a 610U.
::::::::::
::::::::::Dennis
::::::::::I don't know if there is a difference. I was using the model number of a picture of my radio. It may refer to the color of the cabinet. Thanks for any help.Bill
:::::::::
:::::::::Dennis,
:::::::::
:::::::::I have a photofact set 283 folder 6. It is marked Granco 610. The back of my radio says 610U. May mean the color of the case? I just included it in the model #.

::::::::I want to thank Tony and Dennis for their help. I have the radio playing now but the small tuning slug is broken. How should I proceed? Some of it is still in the tube.Volume is low. Is that due to slug?
::::::Bill
:::::::Edd,
::Thanks for replying. I may have to have an interpreter but I think I get most of your comments. I checked the voltage at SR and have 105volts instead of 135. The plate voltages to V1,2,3,4 tubes is 68 instead of 80. Think the filtercaps are bad?
::Earlier,I was trying to say the tuning rod made out of glass or ceramic is broken where it attaches to the plastic mounting holder thing.
::I guess you have already concluded I am new to radio and need a lot of learning.
::Thanks for your help.
