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!

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.

That would be my guess, one of those, Im just hoping someone knows exact ohms as ive read its hard on other parts if its wrong.

Heres a pic of the speaker. The numbers on it are 961615-11 and 2746505.2 the - and . could be wrong of course.

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 host all photos I post on a 3rd party site for a few reasons: One main one is that storage space is small so I rather save space for file types I have to use VK to host like .PDFs and .Zip. Also, Vk's interface is a bit clunky, and most pics I don't like to have access limited to those logged in.

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....

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
