Conion C100 resto

[stragulus]

Hey Eric,

How did you attach the trim to the case? My lower section is loose as well and I need to re-attach it. Do you clean up the old glue and then reapply new glue, and what kind?

 

[caution]

Nah, the old glue doesn't hurt anything. I used RTV silicone sealant to attach them.

Hey Caution
After changing the caps on the tuner board, did you have to recalibrate it?

 

[caution]

Sounds fine! The fine tuning is typically done with polystyrene or ceramic caps, which are prone to less drift/failure.

Great thread almost out of this planet with the pics shown by a pro at work.I wish i had a fractal of those skills.
I just want to ask the pro a question of how to address issues like those.
I do not seem to find a pro with "electronics" skills combined with restoration skills.
Is it a good idea to address a "modelist" for the case issues(glass colour bumps cracks)?
Do you have people that actually send boxes to you for such resto?
Should i address somebody in Europe for such issues and tackle the pay and shipping costs?
How do other inexperienced members tackle such problems?
Thanks

I joined this a while back and have been stagnant in my posts, but the work by Caution is always in the back of my mind when I think of improving my boom box. You're an artist and an incredibly gifted technician, sir. If I'm in a bind and I need someone to figure out a way to get it resolved, my preference would be for Caution over McGuyver any day.

Hello,

There is another Conion radio in the UK, in Manchester more specifically. From what I can see especially in this pinned tweet that ALL boxes appear to be restorable. would like to either have a go myself or be pointed to a person who can do this radio justice.

I do not know what shape it is in so I am going to post pictures and give information etc if I am in the right place and this forum is still active.

 

[harry.stone1111]

By the end of the week, I should have a new lower cassette drawer manufactured for my box.

Can you give me the formula for the treatment you apply and if there is any trick in how to apply it? I can see most of the ingedients in the photo, but I can't see them all and I don't know about how much of each chemical. I live in Florida and we got plenty of sun.

 

[Dbzerk]

Hey Caution, just a question about your re-capping. Did you glue down the new caps, the ones that were previously glued onto the board?
In the process of doing my recap..

You need a bottle of "40 volume" hair bleaching cream. In the unlikely event you can't find the cream version you can add a thickener like guar gum, xanthan gum or arrowroot. Paint it over the entire piece and cover with clear plastic wrap to avoid drying out, and set in the sun for a while. It's common to accelerate the process with a dash of Oxi Clean, but I'd skip that. 40 volume's hydrogen peroxide concentration of 12% is plenty strong enough as-is. You risk over-processing the plastic, which causes this pattern of white marks where the plastic originally flowed during casting, which is irreversible. A ton of info on blogs is out there from others' experiences, whitening everything from action figures to game consoles to sneakers.

Yeah I glued the five big ones on the amp board but it's not a big deal if you don't.

Amazing. It seems everyone on here is great at working on these old boxes. I find it very intimidating to start to work on these as I am just starting out and don’t have an electronics background. I guess you just have to get in there and do it eh? Anyone k ow of any basic electronic courses or any course specific to fixing old boomboxes?

Thanks for the info, my friend. I think I'm officially scared to do it. It might be green, but it still looks pretty good.

Just got reading this thread from start to finish. Fantastic work caution. You've set the bar with your dedication, thoroughness and attention to detail. Thanks for the inspiration!

Oh my, this was an incredible read and restoration. It's better than new.

 

[testacorsa]

I just have to chime in as well. What a machine! What a restoration! My hat is off!

I might as well post the info I put together for the recap...

Price breaks at 25pcs. for four of them takes it down to $57.64 and yields 13 extra capacitors.

EDIT: I found ten more electrolytics while reassembling for testing, on the LED meter boards and the mixer knob board. Here is how to adjust ordering if you want to replace them as well.

Mixer knob board: (4 total)
C501 0.22@50 - Order one more of 0.22@50
C503, C504 0.1@50 - Order two more of 0.1@50
C505 100@10 - Instead of 4 there will be 3 extra from qty. 25 order

LED meter board (right), LED meter board (left): (6 total)
C601, C701 4.7@25 - order two more of 4.7@50
C603, C703 1@50 - no longer have one left over from qty. 25 order, need 26 now
C605, C705 47@16 - Instead of 5 extra of 47@25 there will be 3 extra from qty. 25 order

I been thinking about recapping all the electrolytics.
The links you have set up no longer work.
It has been a long time since I had done this type of work.
My understanding is the Aluminum Electrolytics are self-healing. Which gives added lifetime.
I would think the original type of cap would need to go in the unit? Even though the poly-Aluminum may have a lower XC resistance.
When you list 5mm on the caps. Is this the lead separation or the height?
I re-arranged your list in two different files and have attached them here. {Unfortunately, I cannot attach a excel and word document on this site.}

Are there capacitor manufacturers I should stay away from?

 

[Tinman]

Damn, I wish there would've been a list like this for every box I've recapped, lol.
One possible correction, I assume the (2) 4.7 caps are for the tweeters and not the woofers.
