Hi All
New to the list, so can someone explane. I have a Henry 2kd classic desktop
amp.
I have a problem when I put in a new set of 3-500z and it want to take
off.(osilating for give typing and spelling skills.) So before I put in the
suppressor retrofit-kit and the Glitch protection. BTW I put the older tubes
back in for now. Should I do this retro fit kit and if so or not , Why?
Second ? is Henry doing the modifacation on newer amps?
and third ? the 8k has a set of buit in watt and swr meters built in . Can
you do this on the 2kd classic. I hope that this is the correct place to ask
these question.
