So I did a board using the Tyr tricks, moved things around to accommodate the toroid, and did a prototype.Īll wins. This is why Tyr runs fairly cool, and still delivers the benefits of Continuity.Īnd, I realized: we could put a scaled-down version of this in Aegir 2.Īnd that’s about the time I started thinking of it as “Aegir 2,” something distinctly different than Aegir, something that really upped the Aegir game. So, Tyr was the place we experimented with Enhanced Continuity, and discovered that we could use a single corrector to linearize a slew of output transistors, rather than one corrector per output. There’s no way Tyr would be able to use the original Continuity idea from Aegir and survive without melting down. This was especially pressing on Tyr, given the high power output targets. While we were doing that, I was putting the finishing touches on Tyr, including deciding what kind of Continuity we’d be using (re the Tyr chapter: Embedded Continuity vs Enhanced Continuity). How many is too many? Like 3 years worth.īut that’s not the end of the story, not by a long shot. This is in the pre-ERP days, and it illustrates the problem with flying by the seat of your pants. The mistake being: we ordered wayyyyyyyyy toooooo many Ragnarok 2 transformers. Happy trombone: mechanical noise was a lot lower, even lower than the best EI transformers.Happy trombone: power output increased slightly.Sad trombone: noise floor remained the same.All I know is a Ragnarok 2 started gracing my desk as soon as the toroid happened.Īnd, as soon as we did that to Ragnarok 2, I started wondering: what about a toroid in Aegir 2? Because the Ragnarok 2 and Aegir transformers are virtually the same, other than the insane amount of shielding we wrapped around the Ragnarok version. I can speculate that the original Ragnarok 2 was a bit “fat” sounding and the new transformer leaned it out complementarily, but that’s a guess. Sometimes you don’t know what will work and what won’t. The toroids that Mike likes to make fun of work better in Ragnarok 2. Oh and they all worked-no sorting necessary.Spurred by the difficulty, cost, and reliability problems with building an EI transformer, wrapping it in mu-metal, and potting it into a welded box, we decided to try a toroid as an alternate. The bit of luck came in the transition from an EI transformer in Ragnarok 2 to a toroid. The first piece for a new Aegir fell into place due to a fortuitous finding, and a mistake. Aside: and for those saying “throw a choke in it,” I ask, “Where?” There’s no space.
