sorenb Posted January 25, 2016 Author Report Share Posted January 25, 2016 (edited) Thanks to all who have paid. Unfortunately I don't have a record of the paypal <-> Head-Case-ID of each and thus have no way of keeping track of who has paid. Which is why I asked for: " Please transfer the amount stated in the spreadsheet to [email protected], putting "Group Buy DA, Head-Case ID" into the notes field. Those participated in Caps or Circlotron GB I can figure out, but others I cannot unfortunately. Sorry for the inconvinience. So people who have paid and not participated in Caps nor Circlotron GB please send me a mail with your Head-Case ID and shipping adress while we're at it ? /S Edited May 1, 2019 by sorenb Quote Link to comment Share on other sites More sharing options...

sorenb Posted January 26, 2016 Author Report Share Posted January 26, 2016 This is the relay needed for the Digital Attenuator I have added the part to the spreadsheet here. The price ea is USD4.39/ea, If more than 500 the price is < 3USD/ea. The quantum price is contained in the sheet and thus the price (in the E8) will show actual price according to the total amount. Please add the amount you want. Thanks. /S Quote Link to comment Share on other sites More sharing options...

kevin gilmore Posted January 26, 2016 Report Share Posted January 26, 2016 (edited) the attenuator resistors are not actually 10k, they depend on attenuation per switch and total impedance. Edited January 26, 2016 by kevin gilmore Quote Link to comment Share on other sites More sharing options...
Aive Posted January 26, 2016 Report Share Posted January 26, 2016 Hey Soren, just sent you an email confirming Head-case ID, Paypal email address and shipping address. Just in case it ends up in your junk, yes I'm Jodi Quote Link to comment Share on other sites More sharing options...

luvdunhill Posted January 28, 2016 Report Share Posted January 28, 2016 You might also look at the NEC / TOKIN / (Kemet? lost track) EA2/EB2 series relays. Quote Link to comment Share on other sites More sharing options...
Kerry Posted January 28, 2016 Report Share Posted January 28, 2016 Yeah. Those particular relays are just an example of what can work. Same foot print with 4.5V and low current (19x ohms for the Omron) would be fine. Quote Link to comment Share on other sites More sharing options...
sorenb Posted March 4, 2016 Author Report Share Posted March 4, 2016 (edited) Did a brief check at Mouser in rgrds to MAX's+resistors+capacitors ~ 70USD ...if buying in quantity > 25 sets ...it drops to some 35USD, if there's interest a Group Buy for the this can be done ... Relays are due monday next week, and shipping of Dig.Att+relays will start hereafter unless people want combined ship with Über and/or Dig.Att.Kit Sheet Edited March 4, 2016 by sorenb Quote Link to comment Share on other sites More sharing options...

Pars Posted March 5, 2016 Report Share Posted March 5, 2016 What is in the Dig. Att. Kits? The boards I have are the first version, so don't use the MAX chips, but I could be interested in the resistors, etc. Quote Link to comment Share on other sites More sharing options...
