Respectfully disagree with Mechans; although his concerns are very well taken. But, $75 to get a taste of what tubes are all about? No brainer IMO! These Scott amps can be very sweet sounding, and will definitely let you hear what the fuss is all about; look cool too. But as Mechans mentioned, you should not try to drive anything other than a fairly high efficiency, easy load speaker. With an efficient small box speaker, the Scott can sound really good.
Sounds like cost is a conern for you. If you are reasonably sure that the amp has not been abused you are probably in good shape. Check to see what tubes are in there. Probably Telefunkens, which last a long time, and are probably worth more than $75 by themselves. Even if the amp is not working, it is worth much more than $75 for parts alone (transformers). I would buy or borrow a Variac and bring it up to full voltage SLOWLY, since it has not been turned on for a long time. Go for it!
