It's been about a year since I had Steve complete a Hazen modification on my Decware SE84CS EX.   That coupled with substituting a couple of  cyro'd SV83 output tubes for my previous Genalex Gold Lion EL84's (reissues) have simply put me in sonic heaven.

Kudo's and thanks from a very satisfied customer.  A lot of friends with very expensive, generally high powered amp systems, just shake their heads in awe and amazement.  Nothing like a few converts!
