Thanks for all the encouraging words and your time Mark! Also a rather impressive de-solder and bit of socketing there!

The new socket will help when the rest of get sent the wrong chip...add it to the parts list for the kit. In fact I am adding sockets to everything I have!

It's been a while. Is there any movement on this?

Yeah, I've been distracted with other things.
Hopefully at the weekend, I can do some more. I'll then post an update here.

I just used the "slave tape" output on my 1980's prototype (pictured at the beginning of this thread) to copy an entire tape for a friend. The clone seems to load even more reliably than the original! Can't wait to see these kits distributed, once they pass muster.

Afternoon Lardo Boffin
Okay first, sorry that this has taken a while. Too many distractions
So after repairing my audio sine wave generator (a PP3 leaked and corroded all along one of the connection leads) I have completed some bench testing.
Along the way, I discovered another track break. Now repaired. I also tidied up a couple of other connections.
So as far as bench testing is concerned, it works fine
. I'll post the results a bit later (need to convert to a forum friendly format).
Now just have to find a ZX81 cassette tape...
Also can you please send me your current address via PM so that I can return it to you.
Mark

That's great work Mark, thank-you.
The table seems to show the unit very stable once the "lit" threshold is reached. It never occurred to me to quantify it like that; I just know the darn thing works.
Here's hoping for your problematic tapes Lardo,...
