Meskandar if you know someone who does a little soldering the mods are not difficult. Here is a link that shows what needs to be done. It's for a 302, the mod would be virtually the same. http://www.audiocircle.com/index.php?topic=17354.0
If not see what a local tech would charge. I think Dave wrote the article a few years ago it was less than $120 in parts. More stuff could be added but it would get you most of the way there. You would probably be very happy.
Don't think about the preamp now. Just my advice. If you can have someone change the parts for you, it would be worth it. But if you need to send it in to have it done? You can also look for one that's modded to come up for sale.
The 302/502 are the same amps with different bias resistors. I have not looked at the 202 but I believe it is the same with different/smaller transformers? Good luck and as other said you won't know until you try.
