Hello everyone, and Thanks for reading my sad tale.
I have a Cybertwin, bought it brand new when they first came out 10 or so years ago. Rarely leaves my house..Haven't played it in a while. been dabbling in acoustic stuff. But anyway..came down stairs last night, and only the "amps" that use the dyna touch tubes would work..everything else no sound at all.
Could all of the other tubes have blown at same time..Doesn't seem likely.
I have restored it back to factory defaults..still the same.
Any help would be greatly appreciated.
Thanks, Glen

I have a CT too, and from the symptoms, probably you need to replace the two preamp tubes.
