[AMRadio] Trade nos Stancor A-3894 poly-pedance 125 watt modulation xfmr

[Bob Login]

Hi Paul, Thanks for your offer. Need more info
are the first two 115vac primaries or 230/115? My first
thought is that the 3000vct used in a bridge
would give more than 3kv at half the current
and that would be ok. Can you describe the
3000vct size, weight. Is it potted...manufacturer?
