If that voltage is when it is disconnected from the amp, then it is normal. The adapter has a high output resistance, which when under load drops the voltage down to the specified 18VDC.
If that measurement is with the amp connected and running, then it is probably too high.

Overheating & Hum FIXED
Thanks to PSHITNIS I fixed this problem for ~$5. First I like to say I know very little regarding electronics. But I'm good at following instructions. Ordered those capacitors from ebay. Over 3-weeks shipping time from Hong Kong. I'm on a tight budget, so this was worthwhile. Kudos to pshitnis.
