[Harp-L] Suggested modifications to a Peavey 210 Delta Blues Amp?

["Billy James" <billyjames@xxxxxxxxxxx>]

Has anyone in HarpL had experience undertaking a  tube swap [or any other harmonica amp enhancing modifications] to the Peavey Delta Blues 210? Apparently this was the harmonica amplifier endorsed at one time by Jimmy Hall of Wet Willie. It's a good looking,affordable and importantly reliable Peavey amp [unlike some of the other cheapies].
*Any useful information will be very much appreciated.
