Zercom Max Z Telephone Hybrid Interface Mixer W/ Bag - No Power

Description

Estate find,  I plugged in adapter and it does not power up.   seems like simple enough, there is a power switch and appears to have proper adapter , but no power.
cosmetically looks good, has canvas bag, but again no power , no display.  cosmetically just a few old masking tape type spots on top.
No clue why no power?  bad adapter ? fuse?  more?
bag included, adapter included.  no directions.
Final sale as found,   as-is, priced to sell.  thanks
