Buying tube amps on ebay can go well and then it can suck. I bought an sb-200 and the person who assured me that it would be packed very well threw it in a box full of peanuts and it arrived wasted. Case was crushed, chassis was bent, power supply board was busted from a direct blow. It was in immaculate condition when shipped but it arrived a fixer upper. I was lucky I got a little over half my money back. Straightened out the chassis, rebuilt the circuit board with epoxy and made new traces. I got 98% of the case straightened out and bought an excellent pair of new tubes.It's not the 9.5 out of 10 I bought but rather an 8 out of 10 that works like brand new.If you buy any amp with an internal transformer make absolute sure that they pull the tubes and box them seperate, pack the amp very tightly in foam and then pack that box into another with lots of foam packing. You have a much better chance of the amp arriving usable. Myself, if I ever buy another amp off ebay with an internal transformer, It will have to be picked up and simply not shipped. I paid 330 dollars for my amp, it's easily worth 300+ again but I have some serious hours making repairs and re-soldering every single connection in it. OH, yea.. 700 bucks for a absolute mint sb-220 is over priced. May 750 or so for an unopened unbuilt kit.Thanks for reading my story, Been a pissed off bird here lately!
