Purpose/Replacement part 2064 in Collaro Conquest?

[jtwiddler]

Hello,

I've been going through the excellent restoration instructions in this post on restoring a Collaro Conquest in a console I'm restoring for my wife:

https://www.vintage-radio.net/forum/...ad.php?t=68177

The post includes a link to the service sheets for that model here:

https://www.vintage-radio.net/forum/...llaro+conquest

and therein is contained a link to "Figure 2" of the service manual here:

https://www.vintage-radio.net/forum/...6&d=1255736647

My issue is, everything seems to be present except for part number 2064. I have no idea what this does, it's right by the main spindle the turntable is on.

Does anyone who has this changer know what this part is for, or how I might rig up a replacement or workaround?

Thanks!

P.S. I was going to reply to that thread, but it's closed.

Part 2064 is part of the end of record change cycle. As the arm gets to the end of the record part 2064 engages with a stub on the turntable bearing, is pushed to the right and that engages with the cycle change mechanism.

Why is yours missing?

Good question! I recovered a console from a junk collector, been restoring it. The tube amp is almost done, but I started working on the turntable and ran into this :/

Do you think it would be possible to rig something up if I can’t find a replacement? Would really prefer not to buy another whole turntable off eBay or something just for this little part! Lol

Can you post a picture of the top of the sub chassis?

[peter_sol]

If you are referring to the part which looks like a rubber ring on the end of the trip lever. Later decks omitted that part.

[jtwiddler]

I've got it pulled apart right now, attached are a picture of the top of the unit, and the changer with the place where the missing part would be circled in orange.

I'm sorry I'm new to this and don't know if this covers the subchassis or you need a different picture. Let me know, thanks for any help!

I’ve attached a picture of Collaro Challenger,that I serviced a while ago, it clearly shows the part you are referring to. I’m no expert on these decks so I can’t give you any advice, except I found it well engineered.

As I have said. Later decks don't have that part on the end of the trip lever. They left it off to reduce weight so less drag on the pickup arm.

[peter_sol]

If you look at the sticky items on the HiFi section of the forum you will see the servicing of the Collaro Studio C60 deck. That will show the mechanism you have.

I’m confused. My turntable is a Collaro conquest, I used the sticky here to service it.

Is there something about the Collaro studio post that isn’t covered in the other one?

[peter_sol]

It just shows the later type of trip lever fitted to your later conquest for lighter tracking weight. It shows that you have nothing missing. Collaro were constantly improving / changing things.

[jtwiddler]

Oh awesome, thanks @peter_sol! So I don't need a part there - great to know. Thanks so much for your help.

So I hooked the turntable up to the tuner in the console (without the changer part attached), turned on the tuner, and tried starting and stopping the changer.

It will start (the wheel will keep spinning) in about 1 and 20 tries. But when I get it running smooth and turn it off, I have to flip back and forth between start/stop and auto/manual start to get it to start again.

Would this indicate a problem with the switch? Any ideas?

[Edward Huggins]

It more likely indicates a problem with the linkage as I have had the same issue on my "Conquest" here.
Noting your comment in Post #11, the Collaro "Conquest" and "Studio" mechanisms are very similar.

[John10b]

I had a problem with the Challenger ( similar to Conquest) mechanism being temperamental. The switch mechanism was a bit loose, but this was aggravated by the pin linking to the switch, which had broken the connecting lever, see pics. I was unable to source a new switch so it was temporarily bypassed.
