Mark IV for a V some kind of trade maybe???

I am very interested in the V's Clean and Mark I modes, I am not totally sure on the Lead channel yet, but maybe I can work with it. I love the Lead channel on my IVB. I have some replacement caps for the DC filament supply that needs to be changed to 16 volt, the factory installed 10 volt and has been a problem with some of the IV's. Anyway I am going to try to check out a V this weekend, and get those caps replaced in my IV, and give it a good listen to decide if I am going to let it go for a V or other amp. Any suggestions welcome! I don't know if anyone is interested in some kind of trade here, but I am putting it out there
Thanks!
