Hi Ken. Yes the schematic sheet shows the EV 26s. Not sure what the replacement part is. I got it from V-M Audio enthusiasts.

I am looking for a preamp to connect to the tape in RCA jacks so my phone/ipod will be as loud as the record changer.

Also going to add binding posts and a switch to use external speakers, instead of the old 4 prong plugs as installed.

thank you
BruceF

Thanks for the links to cleaning up the record changer. Tore into it this morning and cleaned and relubed the mechanism. It now works as it should. Time to finish this machine up.

Thank you
BruceF

Have been busy with some other things lately(cataract surgery), but will be back to this soon.
Last time I used the record changer, it was dropping the stack, only 3 or 4 45s, It sounds like maybe the parts in the spindle need a little more cleaning.

hope all had a good Thanksgiving!

Yeah, a VM changer should be pretty silent, so it may need more lubrication. Happy holidays, Bruce :D

Hello I am back with a new set of eyes :shock:
I have been trying to get the record changer to not drop all of the records at once, and have found that the lever that pivots in the spindle to kick the next record out feels rough and does not drop back down to the lower position when the next record hits it. I have cleaned with contact cleaner and used very light weight lube on the pivot area. When i left to go to work this afternoon it was still dropping all the records.

I will try it again in the AM, but if that doesn't clear the problem, have any of you taken the spindle apart? Do you just push the pivot pin out and the polish up the lever and the inside of the spindle?

Mine was made in May of 59 and has a point on the lever that looks like it should catch the next record, but is worn and not very sharp.

Thank you
Bruce

I think I figured it out, after finding what the spindle should look like on the V-M website. Mine is missing the dome cap that guides the record down to the ledge where they should hold station until the unit cycles. I'll post a picture when the new spindle gets here. I assume the cap is stuck in the 45 adapter, which is missing.

That was it. Missing the top cap on the spindle. I made a quick one on the lathe this evening and it is now working fine, no more dropping all the records at once. A replacement spindle is on the way. I will post picture of the spindles for anyone else who runs into this problem. Seem VM only made this spindle for a couple of years.

Here is the picture of the old spindle, missing the cap, and the replacement complete spindle. Unit is now working very well. Very simple to replace, a little heat was required on the fitting to loosen the old grease. EDIT Zenith Cobra and Customatic record changers built after April, 1959 and before 1961. EDIT

Yep, that'll do it. That piece is rather fragile, it's easy to see how it could be broken. I'm glad it had a happy ending

Got the last wax capacitors changed. Sounds even better. Don't stop until the wax caps are all out. The 2 wrapped around the bass control pot and the 2 way over on the left. Played it about 4 hours with my cell phone plugged into the RCA jacks on the back and was now plenty loud.

Done.
Rewired the speakers to use the 3 1/2" with the right speaker and the 5 1/2" speaker with the left. Added a filter capacitor .22uf for the 3 1/2" and 3.3uf for the 5 1/2". really sounds great, playing some Stray Cats. Time to bring it in the house.
