Yes the one with the mini cartridge. Motor runs fine but the entire cartridge holder, tape heads and the cart itself broken beyond proper fixing, has been badly repaired over the years with wrong screws etc so nothing goes together properly any more. Had it kind of working in a nicely broken sounding way but like I say I think I need to hack some other tape mechanism into it.

Do you have this type of "Apollon tape"?
The top problem on those tapes with that unit is the "tape pressure pads"
do you have any squishy foam pads that IC chips are stuck on during shipping?
make replacement pads for keeping tape on tape heads......................
insert under tape in case.......................................
the old pads on those tapes disintegrate over time..................
you can hack something together even if it is simple tape loop in Apollon case
btw felt didn't work as well as IC chip foam
get creative when troubleshooting
best of luck
cheers

silly question time....
can you somehow mount the record/play heads so they make better contact with tape?
sounds like your Univox tape delay unit will function with some creativity from your description IMO

Yep it's a that same kind of cartridge.l, totally broken tho. Ah the IC anti-static sponge idea is a good call. I've fixed 8-tracks before with some kind of window insulation foam tape stuff too

That was the plan but it's broken or loose in so many places that it barely functions :) I did try attaching a walkman temporarily and that seemed like it would work, I should properly rebuild soon that way :)
