  1. Any plans of high current GRLV? Current version limits to 1.5A
  2. is it possible to make BAL-BAL into zero gain? Just like SE-SE, it's unity gain (When BAL-BAL is 0db gain, SE-SE is -6db gain, is this correct)
  3. Regarding those big caps on the fat HV carbon board and the circlotron 900V board Here's the list per ear fat hv 550v 680uf *2 in parallel = one 550v 1360uf circlotron 470uf 550v *2 in series = one 117.5uf 1100v 470uf 500v *2 in series = one 117.5uf 1000v here's one set, per channel needs two sets ---> and then = two sets = two 117.5uf 1100v + two 117.5uf 1000v (these four caps are separated) I met a resident in my building, according to him, he owns a small house to produce caps, consumed caps up to 2.8kv whatever normal value, is it a good idea that I order two 550v 1360uf eight 117.5uf 1100v for the circlotron? Now it's 10 caps instead of 20 Shouldn't be 360vac?
  4. is this input + output board + attenuator also the same as here? Or put the attenuator in between the two boards? https://www.head-case.org/forums/topic/12024-and-now-for-something-completely-different-part-3/?page=6#comment-724017 BTW, about these output boards, the orginal one and the newer one, could we wire them to output SE signals?
  5. Hi there, speaking of CREE driver, here's a pricy edition of c2m1000170d still 1700V, but rates at 72A http://www.mouser.com/ProductDetail/Wolfspeed-Cree/C2M0045170D Will this high current version be stable at 100ma or even 200ma? (Maybe at that level, have to mate with a $$$$$ source to hear the small difference compared to 25ma) Looks like there will be higher voltage CREE driver coming out in the future, let's say, 2.5kV 5A (HV version of c2m1000170d), is the 2.5kV Cree driver still have benefits in the design, ie. of the electrostatics amps?
