Info on Marshall Lead 12 mini stack

[NHTom]

Hi there,

 

Thinking about picking up a late 80's Marshall Lead 12 Mini (micro?) stack for a practice amp.

 

Does anyone know if these heads had a headphone jack? I know they had a few years, and I believe the one I'm going to check out is a 1988.

 

I have heard mention of scratchy knobs on these, anything else to watch out for?

 

Thanks,

I believe the one I had back in the day had a headphone and line in as well.
