Hi everybody!! I need this schematic for a complete restoration of a Ford 1958 radio. I will appreciate any info.

Thanks in advance!!
Carlos

Techpreservation has it..... http://techpreservation.dyndns.org/schematics/58/58_Motorola_84MF_90.djvu

Its DJVU frmat, if you cant get it, post back here with an email, and i'll try to convert it and send it to you

Hopefully, this is mo' bigger...plus its extras....

'Mo info available if needed...never had any problem with the ray-dee-oo on my unit, with my custom add on / built in RCA 45 rpm record player.
BUT... its retractable hardtop feature was a real "rattle trap" !

Thanks Edd!! Its an excellent schematic!! If you have some alignment info, will appreciate it!!
Thanks Jeremy too, but couldn't open the webpage.

Maravilloso!! wonderful :-))
Thanks Edd, only need to replace all three broken tunning cores, (only could get smaller ones), and will try to put it on!!

Thanks Again (Ford Custom '58)

Hi Edd, Im here again. Please if you have any info about R3 transistor bias calibration, and anything else, I will appreciate send me it.

Thanks in advance

My SAMS references give no info as to the specific adjustment of that pot and if it was mine I would be sure that the supplied references red marked electrolytics were fine, and then monitor the current consumption in the green referenced box to be sure that the quiescent current was not above that reading and also place a sine signal into the AF section while monitoring the output stage with a scope and
see if the response on sine purity was good at that setting of the R3 bias pot...just don't run the AF out unit too hot, being old Germanium it can get away from you with rising heat, beyond what its protective thermistor is already able to compensate for.

Hope your smaller sized tuning inductors worked out for you, If excessively "wobbly" I was going to suggest a bit of effective external diameter build up with a layer / layers of conformal fitting heat shrink tubing.

EDD/Carlos,
I've never tried it, but suggest that plumber's tape (teflon) might be a better choice (more conformal) for building up the outer diameter of a tuning slug, and in addition, easier to adjust.

Edd/Marv, hoped could calibrate R3 without scope, but its the best way with it. Thanxs both!!

About the tuning slug, Its good idea to use teflon, but think it could loose with use, what do you think? I dont put it yet, because im still thinking how to repair original ones, witch are broken only at union sector.

At the end, one question about capacitors, doy you think will be better to change all electrolithics/paper ones or only bad measures??

thanks in advance
Carlos

Carlos,
Once they are adjusted, the slugs shouldn't require regular tuning, so teflon should work fine. Don't understand "broken at the union sector"

Hi, when i tell you tunning cores, I1m referring to the ones wich ar moving and tunes the radio (three moving cores).

Thanks
