Re: dead reds

Well it's not quite right as it is but a working version will be finished soon, when I say soon I would imagine within the next 6 months.
Apparently there is another version of the amplifone HV transformer floating around a few people in the States, its being tested right now so someone else may have a good version for sale very soon.
Does anyone know the part number for the 6100 original Transformer? I can't see it listed in the manual

  Hi,

  It has to work.

    Hi,

    I hate dig up old bones, but again where is the by far cheaper working model. I know I does not mean much by now but
    Wintron for US customers is the best bet. The HVT you made or may nor work, does it really work???? Simon?

This flyback was/is being designed from the ground up, to work in the
Amplifone circuit as a drop in replacement. It uses the same primary
input voltage and (is supposed to) resonate at the same frequency.

A custom mold was made for the outer housing and a custom bobbin with
terminal pins in the end-flange spaced specifically to fit the Amplifone PCB
was also developed as part of the project.

Cinelabs released an easter egg photo of the FBT some time ago when
we annouced the Sanyo replacement FBT, but as we've been encountering
the well documented issues associated with developing a replacement
for this particular circuit, had been keeping it low profile, so as
to not get people's hopes up (and prevent a flood of "is it done yet"
emails).

Regarding using existing TV FBTs, I really don't want my vector games
to sound like they've got raster monitors in them!

being about 9kv too low :(
      9kV out, bummer :( Is this a 'standard' model of flyback or a custom job ?
I ask as looking at 'modern' flybacks they mostly seem to run from a
120v-160v voltage. So my thinking goes.. using a 48V available as a source
( the -24 to +24 on the Amplifone board ) you'd theoretically only get
a voltage stepped to around 10kV ? Correct me if I'm wrong ;)

Also for general interest I've seen monitor/TV's running around a
50V supply into to a boost regulator to generate about 130v before
powering the primary of the flyback.

Great idea for a drop in replacement BTW, hope you get it working.
