The new Western Electric in Rossville GA has been mentioning their new WE 91E amplifier for at least a couple of years now. No surprise, it's a single-ended 300B amp but with 20 watts output! Yes, single-ended 300B with 20 watts output. It may be closer to being released because they are providing some more details about its circuit design. From the WE website: "Experience over 20 watts per channel-a first for the 300B. This never before realized level of performance has been achieved with a completely new approach to SE amplifier design. Developed over two years, the 91E's circuitry intelligently steers the parallel feed constant current source (SCCS), allowing the tubes to deliver more than double their previously rated output of 7-8 watts. You've never heard the 300B like this before. "Our patented steered constant current source always keeps the tubes within their safe operating area. This means full power dissipation without sacrificing tube life." On the same page as the quote above, under additional features, they also list "Class A3 parallel feed single-ended Triode topology" and "Zero feedback". My questions are why has nobody thought of this before and (for the amplifier techies out there) given what you know about amplifier design, can this truly sound great given its design? Thanks!

This "Simple 45" circuit of Dan Tucker and Dan Schmalle, breathed on by Steve Brown was the culmination. All the kids thought it was the best they'd ever heard. Then five years ago I decided I needed more headroom, found and built the Mullard 5-20 Mono-blocks. I have about $1800 in parts, not $1562 per watt ;-), and remain thrilled with their sound quality whether girl and guitar, Dizzy and Charlie Chan, or The Symphony Of A Thousand. These are the amps I'll be buried with. |
It's a scare tactic. :) (nt), posted on June 25, 2021 at 19:49:59 | |
