Drew, Never got to buy this pcb and noticed the out of stock label on Kens site. Did the "aren't available anymore" come from Ken? I was thinking of a building a couple of these myself. If Ken needed an order for the minimum of 3 (as he has for blue special order boards) I'd grab

Anyone have a spare "Master Divider" (CGS22) PCB they don't want? Due to lack of interest, they aren't available anymore. Being the oddball that I am, I want one :) thanks, Drew

I'm trying to build up the Tube VCA and the Power Delay projects and it's been a frustrating situation. Does anyone have a current list for part numbers for these? I have been looking to fill these orders for the past few weeks and it's just so hard to tell from the Mouser site i

Okay, Just finishing wiring up the front panel and pots- A few questions on the wiring of the pots- I based my front panel on the Elby CGS48 panel http://www.elby-designs.com/ken- stone/cgs48-fpd.pdf and here are my questions: -What are the "Processor Pots" 1 + 2? are they the PW

No problem :) I haven't bought bypass caps in years, as I still have a couple dozen left. So I would have to look to see if if use the exact same ones. I bought whatever were the least expensive axial ceramic Z5U .1uF caps from Digikey. In retrospect, I probably shouldn't have sa

As has been mentioned numeroust times on this list (and this is a message to EVERYBODY) do NOT use any CMOS chips with part numbers starting with "74xx4" in any CGS design unless that part number is specifically given. CGS designs usually run the CMOS chips from 15 volts. 74xx4xx

The Phillips chips are for 5V (74HCxxxx) use only so they wouldn't have worked here. Surprised the Fairchild chips didn't work. I will see if I can get some time to check it out at my end., Best Regards (Mr) Laurie Biddulph Phone: +61 (0)2 4340 0938 Mobile: 0400 257 645 Elby Desi
