Interestingly 320mH/10R - 50uF - 320mH/10R - 50uF looks really good in PSUD.
Since I build my all single-valvers with "WE Connection" capacitative divider for increased PSRR I'm going to see if I can get away with just ONE section for my next 801 amp :)

Brian.

Low H, low DCR PS chokes

Hi Dave, Jeff Medwin has been advocating the use of the low H, low DCR Triad C-40X, 320mH, 10ohms choke and claiming that the smaller core is an advantage compared to Hammond 600mH, 11ohms for L-C-L-C. Have you, or anyone else here, experimented along these lines? In other words, should I be asking ...

Hmm. My proposal involves 3 transformers, each with two primary coils interconnected such that LHC had R out of phase with L, CC with L & R in phase and RHC with L out of phase with R. The number of turns of each primary coil set to produce the desired ratio. All mounted in the same box as the s...

Good point Raj! :wink:

However I was thinking of early stereo recorded 3-track on Mercury, Command and so on. There was some decent stuff laid in vinyl back then :)

Trinaural-type matrixing using transformers?

Dave, do you think it a feasible idea to use 3 line-bridge type trannys, specially wound with appropriate dual primaries, to provide the 2-channels -to-3 blending along the lines of Jim Bongiorno's "Trinaural" processor which uses <place peg on nose> IC op-amps <remove peg from nose> :?: T...
