CR-70A receiver - UK Vintage Radio Repair and Restoration Discussion Forum

Hi

Wondering if anyone here has advice on how to repair a cracked screen on my CR-70a MKI

It is of sentimental value, my father owned it in Ireland, spent many hours as a kid listening to it, when he passed away I brought it back with me to Canada.

Unfortunately in transit, in the cargo hold, it was damaged and the screen broke. The metal work got a slight dent as well and the paintwork I believe non original, I suspect he resprayed it in Hammerite silver sometime in the eighties.

I have the glass piece but wondered if there was anyone remaking old glass screens? Or advice on repair, have thought about superglue but .......

Thank you in advance

John

Hi John, can't help with glass, but I suspect the paint may be original please have a look at mine. Seems to be light grey Hammerite.

Hmmmm some food for thought there. Thank you

There is a special type of superglue formulated for glass repair.
I have used it and it worked very well.

I think if the break is clean (no missing chips) then it might make a surprisingly good job of it.

There is nothing to lose. If you still don't like it see about having a copy made.

Glueing it together so you can take some really good photos would be the first step towards making a replacement, so it's worth doing anyway.

Ok I am sold, I will try gluing, having a look around locally for a matching refractive epoxy and see how I get on and if no go will will scan to clear acetate and play with that
