Re: Re: 6100 HV transformer in an Amplifone HV PCB

Sorry to chime in late, but I recall an ebay auction several years back- it had an amplifone w/ a 6100 cage. The description read "yes, what you see is a 6100 HV cage running on an amplifone- it works (if you know what you're doing)"

hope your mod works out,
James Hagen
