Studio Standard FISHER 1980's amp


I wonder if anyone here can give me a idea what I can ask for a vintage Studio Standard FISHER
1980's amp.  Model is a CA -880
Besides the power level meter everything is working very well.
Thanks upfront

Can be found at GoodWill for $25! Along with the other matching Studio Standard components. The nadir of Fisher!

The only Fisher gear worth owning are the 50's/60's tube stuff.
donate to goodwill. 
Thank you guys, appreciate your speedy reply!
