ORIGINAL MESSAGE: REPLY: I disagree. The braid itself can present a safety hazard under some conditions, especially if the braid loses it's connection at one end and someone tries to hot plug the oth
Jim, you are 100% correct about a single diode being sufficient for B minus surge protection. I guess we habitually say/use back to back or back to front or reversed connected pairs just in case we s
Not to be flip about this but if we're talking about the safest design, that is in my opinion, to forget about B+ cables and separate cabinets and build the whole thing, p.s. and RF deck, into a sing
Rob, I was thinking the same thing as you. A guy can spend a mountain of cash on interconnects for hv and still get fried. A stand alone supply by definition means kicking the danger awareness up a n
With all this talk about B- diodes etc., I wonder what the recommended safety practice would be for an amp/supply arrangement where B- is not near ground potential; for example, a grounded-screen tet

near B- I think that's a very interesting question, Scott, and I'm looking forward to hearing other folks' opinions. I don't see any obvious way to protect such a circuit, other than fusing the HV l
Scott, Jim and all, it certainly is not as simple as grounded grid B minus protection but there are a couple of options. There are some hefty surge limiting devices available. One series was made by
