1964 RCA VFE 03 Record Player Speaker
I ended out with one of these and need a speaker. The good speaker tests at 37.7 ohms, so if I understand right it would be about 42 ohms. Seems goofy to me. Does anyone have a schematic?
No name on the turntable top or bottom. No tubes. no radio, just a record player. Its like a childrens player but is walnut veneered and on spindle legs and looks nice. Im surprised the cabinet is so nice with such a mediocre changer. Here is a similar one http://www.lotnut.com/app/item.html;...0-0702490f4c46 |

I did some research and I think the Sams folder is number 765-11. Maybe that will help people search. Thanks!

Picture of speaker you seek??

i dont necessarilly need an exact replacement. Im more wanting to know what ohms it is from a schematic before I dig thru my parts. But I will get a pic of speaker on tomorrow. Thanks!

IIRC, RCA speakers were something like 8-16-32ohms impedance.

Heres a pic of the speaker. The numbers on it are 961615-11 and 2746505.2 the - and . could be wrong of course. Last edited by Celt; 08-08-2018 at 05:39 PM. |

Yes, Ill have a look at that for you. The higher (than 8 ohms) impedance speakers were used with early solid state amps that used certain germanium transistors.

PM me with your email address and Ill scan the sams for you. I found the folder but forgot to bring this morning or you'd have an answer by now.
I am out of upload space on my posts and need to go back and shrink-edit some huge files I posted. 7 years is a long time to be posting if you cant keep stuff to yourself

I got this working quite a while ago and set it aside and am now looking at it again. It sounds real nice except for its running a little bit low, like 31 speed. Im fairly sure it is not the idler due to experimenting. Anyway Im thinking its possibly a leaking diode (and I could be wrong!!!) that connect to the motor. There are 2 Im concerned with but before I remove them the number is 1N1692 which crosses to NTE117. can they be replaced with 1N4007's? I have those on hand is why I ask. They are circled in black in the pic. Thanks!

N1692 600ma 100v
1N4007 1A 1000v - should work fine |

Thanks! The different kinds of diodes always scare me a little.

Numbers on spkr. The one ending -11 is what RCA calls a drawing
number. There was a cross reference to get the real 6 digit part number. The one starting 274. 274 is RCA's EIA number. Almost every US mfg had a different one. The 6505 is probably the date code. So 1965 fifth week. Last number probably run number for that week. Common impedance for speakers was 4-8-16 & 32. It is not DC ohms & will measure different. Matching impedance to the design is most efficient & safest. IIRC Sams shows actual impedance. Try to match it. Also be sure there is no DC voltage on the speaker wires before replacing it. Compare to the good channel. A leaky output can pop the spkr or other things.... 73 Zeno LFOD ! |

Thank you for the added info Zeno.
Dave Goodlin was kind enough to email me the sams months ago for the electronics and I found the changer Sam online. These were a strange ohm, 35 ohms to be exact. I was actually lucky enough to find one on ebay the right size and ohms and it sounds good for a cheap changer. I never expected to find one with that ohm amount. I switched the diodes and just now gave it a whirl and the speed tests correct by eyeballing it, so I got lucky. I did order one of those laser RPM meters and will test it for sure when it arrives but its awful close. I was hoping it wasnt the motor. Its nice to have one project done, lol |
