Sell and refurbish?

I currently have a Rotel RX-1050 (100W) receiver, run through a NAD 525BEE Cd player& hooked to a pair of PSB T45's. It sounds excellent and I enjoy it much. Last week I picked up a Sansui 8080 for $20 at a garage sale. After some topical cleaning I hooked it up and wow! For being 30 years old it definitely gives my Rotel a run for its money. The low end certainly delivers more punch although the Rotel has a slight edge in clarity. I am considering selling the Rotel and putting the funds into a complete refurbishment (there's a local shop willing) hoping to make this beast sound even better. Does this sound practical, or would it be more trouble then it's worth. Also, would refurbishing the Sansui really improve the sound dramatically? Thanks
If your current system sounds excellent and you enjoy it, then I think you ought to upgrade to a subwoofer instead. This way you keep that clarity w/the Rotel and improve the bottom end. Your money will be better spent this way. Besides, refurbishing can be quite expensive, if done properly by an experienced technician, and you may only have a very marginal improvement in sonics. Go the sub route and you'll be satified.
An alternative viewpoint. I picked up an old Marantz 2230 receiver for $20 at a flea market. The initial listening test was promising, so I decided to refurbish the unit myself. I replaced every electrolytic cap (~75 of them) with 105 deg C rated modern caps and replaced some of the mylars as well, cleaned and reseated the transistors on their heat sinks, replaced all of the lamps, put in new diffuser paper behind the dial (so it was deep blue again instead of aqua), replaced a broken power switch and a few broken speaker posts, and polished the chassis to a gleaming finish (see pictures below). The total cost for all the parts was <$100, and I now have a kickass 30WPC receiver (a VERY powerful 30 watts, I might add) that is also beautiful to look at, and a bit of a conversation piece. It's now the centerpiece of my basement workshop system, along with an Onkyo DX-702 CD player (picked it up for free) and a pair of Pioneer HPM-40 speakers (also a free score).

So for a total of $120 I have a system that sounds excellent in that space, and a lot of personal satisfaction. It won't replace my main system in a much larger room, but that system cost me >$15K! And that Marantz will be good for another 20 years at least.

In summary, if you like unusual/vintage gear and like to work on /fix things, and you have some free time, why not go for it yourself?

So what do you think?
Good job Ait! I've always thought it would be fun to do something like that. However, I'm always scared off when I see a notice: "Danger, Lethal Voltages Inside". :)
Ait, excellent job that looks beautiful.

I heard an old Kenwood receiver the other day that was pretty damn stout (hadn't been refurbished). Maybe the best thing to do would be to keep the Rotel until you get the Sansui back and make a fair shoot-out of it. It shouldn't be too much of a hit if it doesn't come out the way you had hoped and you would still have a system you obviously enjoy.
