- Hello, today I am showing you a Capehart 41-E changer which was converted to play 331/3 RPM Stereo records. It has a stereo cartridge and a 33 1/3 rpm motor installed under the turntable. The weights on the back side of the tone arm are to lighten up the stylus so that stereo records won't be damaged. The changer plays both sides of a record and then returns it to the magazine, (10" and 12" records intermixed). It will play up to 16 records, both sides before repeating. This mechanism also has a 'counter' which will shut off the mechanism after a preselected number of sides have been played. Years ago I purchased this Capehart changer mounted on the plexiglass base as you see it now. It's fasinating to watch the gears and mechanism under the unit as it changes the records only touching them by the edges !! It can be set for Manual play, One Side or Both Sides. It has two stereo leads which plug into your own stereo amplifier and a reject button on a three foot cord. Thank you for checking out my RUclips videos. This video is still listed in memory of Bob who passed away in August 2022.

I always thought that these two problems require major re-engineering to make it destruction-free for Stereo LPs.
Thanks for posting this
Your changer is one of the early 41-E changers. The early 41-E changers (1946-48) were 78 RPM only, but the later ones (1949-50) were dual-speed (78 and 33). Early dual-speed changers were designed so you could swap the tonearm back and forth between a cart with a 3mil to a cart with .7 Mil Cartridge depending on which speed you were playing. Later when Cartridges with dual styli were available Capeheart adopted those.
I wish I could find an affordable (sub $400) 41-E. All I've been able to find is a 16-E...And mine has pot-metal issues (including a mostly missing turnover arm). The 16-E is not as easy to adapt to LPs. The changer and turntable are both driven off a single motor (no turntable idler drive like the 41) and the tonearm doesn't appear to be made in a way condusive to mounting or adjusting the tracking force of a post-WWII cartridge (read that any cart that has any business playing an actual LP).
Still, If I can cast new parts to replace the ruined pot metal and make my 16-E work at 78 RPM I may try to copy the planetary 78 to 33 RPM reduction gearing on my RCA RAE-26, and see if I can adapt the tonearm to track at a safe/gentle weight for LPs.
That project is on hold till I restore the bargain E.H. Scott FM Phillahrmonic chassis I want to pair my 16-E with.
That is quite a unique operating automatic turntable, and sounds very good. There is one automatic turntable that I never see anywhere, not even on ebay, it is the Lincon 50 automatic turntable.
This is just showing off !!!!! Simply Brilliant and I want one !!!! what can you say ???????? fantastic / I could watch all day Tim.
The proof is in the listening, and your modified-for-stereo LPs Capehart sounds good on every one you've played.
We use this Capehart record changer every night for background music with dinner. The albums are played multiple times with no damage, as they are only handled by their edges. Anyother part of the mechanism that would come in contact with the records is felt covered. There is a Shure stereo cartridge installed in the headshell.
Hello Martin, it was already converted when I purchased it. But, I can tell you that the original 78 turntable motor shaft was filed down till the table rotated at 33 RPM. The headshell was fitted with a Shure stereo cartridge. A counterweight was added on the end of the tone arm.
I believe the two speed changer was designated as 42-E. Probably didn't manufacture too many of those due to less expensive changers from other companies im the late 40s. My 1947 413-N1 came equipped with a 41-E and cost was around $1700.00 new, a rather princely sum in the late 40s.
Very nice engineering.
Awesome 👌
Wow, that is a piece of work! It is surprisingly gentle with the records. I am impressed! Thanks for posting.
Very Kool! Thank you for sharing.
COOOOOOL!!!!!
There must not be many of the Lincolns left. I'm guessing these were VERY expensive machines back in the day.
WOW! I wish I had the money.
Wow sweet conversation, great work 👍
Great changer and modifications. I'm wondering exactly how you modified the tone arm to make it compliant with the more sensitive Shure Stereo phono cartridge. You must have changed it's pivot points as well by adding low friction bearings.
Finally I thank Ebay , Just managed to get one of these amazing record changers ,
please can you tell me where I can get the correct cartridge ?? its Missing,
I just cannot wait until its playing , thanks for the video, " hope you can help me get a cartridge ? " Tim.
The country record that plays... is that Patsy Cline? (Sounds like her... and I love Patsy).
Hello, interesting, you did what Capehart did about 2 years later. They added a 33 rpm tone arm to this changer.
How did you address the two challenges of this changer with LPs?
1. The trip mechanism is very heavy and requires something like 8 grms for correct operation.
2. The changer only works correctly with very thick 1948 LPs. With later (and thinner) LPs, it usually throws out two records at the same time.
I has seen this on E-bay few months ago bid up to $1,000 played 78rmp
How did you convert that changer to 33 rpm??It interests me so much,I want to know how did you convert that changer to 33 rpm
Hi Bob , would you know where I can get my clear purspex cartridge rejuvenated as it has lost it's stylus , many thanks Tim.
If I might ask, what cartridge did you use? Shure M44C?
