Kia ora all

I have encountered many squealing tapes in the collections I'm working
on in the Archive. Be mindful they have been recorded in locations all
over the Pacific so the climate, humidity and temperature has played a
part.

I have great success with baking the cassettes and leave in the oven
for at least 2 days.  If really bad, I will open up the case and drip
some isopropyl over the tape.  I haven't had any yet that I can't
reproduce.  They are all different brands and lengths also.

Hope that helps.

I have had cheap casstes and extra long ones (such as C-100 and C-120) bind and slow down warbling in speed, and usually winding forward and back helps, as well as slapping the casstte flat on a desk to re-align the tape pack.

I have a number of cassettes that display sticky shed but before baking them I'd like to know whether there may be a problem with the shell warping, the pinch pads falling off, etc. Taking the tape pack out of the shell is certainly an option, but I'd rather not if I can help it. Suggestions would be helpful. Thanks!
