July 10, 201610 yr comment_735194 I had some comments back so I've made the following changes: I reversed the SE and balanced outputs I fixed a mistake in the schematic for the negative off-board voltage regulator Thanks to Kevin (of course), Birgir, Marshall and Joachim for your feedback Here's what might be the final...

July 11, 201610 yr comment_735217 This is a good reason to get back into dynamics, awesome work Kerry. Alpha will only do a 1000 pc order last time I checked. Report
July 11, 201610 yr comment_735222 We'll have to look into options. I've sent the board out to manufacturing so we can prototype it Report
July 11, 201610 yr comment_735244 maybe i just got a bad batch, but i had a lot of trouble with the Alpha pots and plan to stop offering it in the GS-X mk2. A large percentage of them have a noticeable lump at a particular point when turning it. Sometimes you have to have a large knob attached first and then turn it slowly to find the spot. but around half of them ended up in the trash Report
July 11, 201610 yr Author comment_735245 It must have been a bad batch as these work perfectly. Some of my first ones had the center bump but I returned all of them. Report
July 11, 201610 yr comment_735246 fine, cram the new digital attenuator in there. should be enough room. Report

July 11, 201610 yr comment_735255 SMD, SMPS... Blasphemy! I'm actually super proud to see HC finally embracing the newer tech. How do these SMPS'es look under the scope? Does extra after-regulation help? Edited July 11, 201610 yr by RudeWolf Report

July 11, 201610 yr comment_735270 I'm in for whatever group buys emerge from this terrific design. Report
July 11, 201610 yr comment_735290 Very cool Kerry! Subscribed! Very nice board layout as well. What did you use for that? Report
July 11, 201610 yr comment_735291 Thanks. The design was done in DipTrace v3. I've been using it for a while and like it. Report
July 12, 201610 yr comment_735310 Unless that software is ExpressPCB. Quote I'd love to try my hand at building one, though it sounds a bit beyond hand tools http://www.rocketscream.com/shop/reflow-oven-controller-shield-arduino-compatible Report
