Scott 222 B tube amp

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!

You did well on the price!- properly refurbished they can be quite nice sounding. However unless you have it on good information that the unit has been recently serviced, I would not run it until you have the power supply rebuilt with new filter caps and have the unit checked over, else the power transformer could be damaged.

With a new set of filter capacitors and other relatively minor service issues taken care of, you can expect the amp to be reasonably reliable for another 20 years or so.

We've been doing a lot of work like this in the last few years but anyone familiar with servicing tube amps should be able to take care of it. I would allow for at least $200 to get things taken care of, although it could go higher than that if the tubes have to be replaced.

You need to be a-bit DIY to handle this amp. The cap banks that most-likely need to be replaced are not cheap and might cost more than you would pay for the amp, but $75 is a great price even for the partially functional unit.
I agree with Mechans that this amp is great for near-field, but should probably mention that built quality of this amp is superior to the modern tube amps.

How slowly are you suggesting?

Minutes? Hours?

It's normally takes 3 min to 'fill up' caps. This much time I guess is needed.
