  8. Short update, mainly to thank you for your opinions and assistance. I've got a Synology 920+ NAS and a couple of 16TB server HDD. Once this is set up and working, I'll decide if I add more RAM and/or a M.2 drive to be used as cache. This unit admits up to 4GB RAM extension, but it's been tested to work well with an additional 16GB DIMM for 20GB RAM. Main concern is how noisy it's going to be with 2 fans and up to 4 HDD, but I can always replace HDD for SSD units sacrificing capacity. Fortunately it can be placed away from my desk.

  13. I think I am going to try to use a reflective sensor - looking at Vishay VCNT2020. I need a mirror or similar, assuming the acrylic platter won’t be IR reflective. Maybe a foil sticker? http://www.farnell.com/datasheets/2614502.pdf added a comparator to the board to adjust the sensitivity

  22. I've never owned any UAD plugins but I have used some at studios with their cards. Be aware that their plugins require the use of one of their Apollo interfaces or a computer with one of their DSP cards installed. I'm not so sure how relevant these systems are anymore since computers are much more capable than they were when these systems were developed. Still, putting cpu intensive software on another computer or another processor system (DSP cards) makes a lot of sense if you do a lot of laptop work or just want to load up a ton of plugins/processing. There are other non-UAD options to get that Neve sound. I have the Slate Digital virtual mixbus and Waves virtual mixer. Both have Neve settings. I prefer Slate. https://slatedigital.com/ I believe it is easy to get a demo or try Slate's for a month or so. Channel strips are nice for mixing and probably half of the plugins I own are primarily for mixing. I haven't done very much mixing in the last couple of years so I don't find myself using them that often anymore. For music production I try to make the tracks sound the way they should in the first place but sometimes I do try console type modeling to add a little something. All a matter of taste I think.

  26. My partner has gotten into watches a bit (I should never have given her that Timex last year, literally just off my coffee table where I had forgotten I had thrown it), and I bought a Tissot Lovely Square for her. The packaging is trying way too hard. The thing on top is a 280 page illustrated history of Tissot, which is included with a catalog that is basically a miniature coffee-table book. I wonder if anybody has ever read that history of Tissot. I bet she'll like it, being a literature professor and all. I also got a Seiko "Tank" for her, which is a surprisingly hard watch to get considering how cheap they are (and holds up surprisingly well compared to my mother's 40 year old Must de Cartier Tank, though it's not quite as nice as my mother's 45 year old Seiko "Tank" that was the first watch my father ever bought her, and which had a similar price retail). She likes wearing my Reverso and my Santos, so I figured square-ish and different would be good choices. The large Santos fits her surprisingly well, with a bunch of links removed (she is tiny), but I figured something smaller would be a good idea for daily wear. Also she can't have my Santos.

  28. I would say it’s a modified KGSShv or Carbon with T2 style current sources at outputs. My intention is +/-400V but +/-450V will be OK as 2SA1968 is a 900V device (I think). Schematically it looks like this. I’ve saved the old, now hard to find, transistors from my first built electrostatic amplifier - an onboard heat sinks KGSShv.

  33. My guide to golden reference high voltage (grhv) variants Here is my attempt at documenting some of the different GRHV board variations. (this will be work in progress for sometime) feel free to private message me with any additions comments, corrections etc. please note the schematic for version 1.5 has been reverse engineered by me from the gerbers and may contain error(s). location of the gerbers: https://drive.google.com/drive/folders/0B_iJFfZStuVhSE5nOHBVdTByR1k golden reference filename naming guide fat - boards which are wider and have less height than the non fat variants L bracket mounting only same as the non fat variants. fat with S as the last character of the filename - boards which are wider and have less height than the non fat variants and the height is about 6.3mm less than the fat variant. these boards also feature more screw hole options for the mounting the pcb to the case including an option of not using an L shaped bracket and mounting the transistors directly to the vertical face of a heatsink/side of the case. a silkscreen cut line is included to guide removal of the L bracket mounting roles to facilitate direct transistor to heatsink mounting. dual - has both positive and negative hv supply with additional bias and both positive and negative low voltage supplies on a single pcb left - has a single negative hv rail and both positive and negative low voltage supplies right - has a single positive hv rail and bias no new in the filename version - 1.5 boards high voltage starts instantly board has high voltage VAC power. Topology is much simpler then version 1.7 and 1.8 and therefore not considered golden reference. new in the filename actual golden reference boards with extensive post pass transistor regulation. new without sw in the filename- version 1.7 high voltage starts instantly board has high voltage VAC power. new with sw in the filename - version 1.8 or later boards same topology as 1.7 but high voltage will not start until dc power supplied to the cpc1117n no dual and no fat in the filename - minimal width and quite high. NOTE placement of the screw terminals for input VAC can vary considerably depending on if the board is a fat, fat S or non fat. Overview of the versions It is the extensive post pass transistor regulation that marks the golden reference out from the other power supply designs as such version 1.5 and earlier not classify as a golden reference since they lack any post pass transistor regulation. No details of versions before 1.5 or version 1.6 could be found in the gerber archives. Apparently pre 1.5 versions had on board heatsinks and ground lanes but there gerbers and not available in the google drive archive. No schematic could be found for version 1.5 although after reverse engineering it was found that the circlotronps.pdf is similar in topology but modified to support 900V output. No bill of materials could be found for version 1.5 and it is not certain what is the power rating for the larger resistors. All versions have the pcb tracks on the underside with no tracks on the top. All versions have no ground plane ALL versions have bleed resistors to help discharge the high voltage caps although version 1.5 and a few variants of 1.7 use a single high power resistor and the rest two 1/2W resistors in series. All versions have the same basic voltage regulator based low voltage positive and negative supplies All versions have the same bias supply although v1.5 has different resistor values. ALL versions use a LT1021-10 voltage reference All the versions 1.5, 1.7 and 1.8 use a C2M1000170D pass transistor All the versions use a 10M90S pre regulator although version 1.5 controls it with a zener string and 1.7 and 1.8 control with a DN2540. 1.7 and 1.8 are almost identical in topology although 1.8 does not automatically start the high voltages. DC must be applied to the CPC1117N to start. note 1.8 does not have provision for screw terminals for the DC to switch on the cpc1117n. versions 1.7 and 1.8 have more post regulation using a second 10m90s (which is not present in version 1.5) after the 1N4007 protection diode. version 1.5 uses a 10ohm current sense resistor and versions 1.7 and 1.8 use 5.1ohm by default. version 1.5 uses a 10K resistor to ground in the 3 series resistor chain to decide the output voltage, 1.7 and 1.8 use 20K to get 400V output. The other 2 resistors in the chain are the same for version 1.5 and version 1.7/1.8 version 1.5 uses two stn0214 which are replaced by two KSC5026M in v1.7/1.8 version 1.5 uses two stn9360 which are replaced by two BC557B in v1.7/1.8 Known non golden reference boards which are variations or predecessors to version 1.5 and golden reference variants NOTE These have not been looked at in detail by me or fully reverse engineered. The cyclotron power supply series follows a similar evolution to the golden reference. earlier cyclotron psus (circlotronps.PDF) use a variation of version 1.5 topology with modifications to bring the output up to 900V. However since it lacks any post pass transistor regulation it can not be considered a golden reference these psus do not have new in their name. The later cyclotron power supplies have the words new or newver in their name on quick inspection of the gerbers appear to be modifications for 900V of the version 1.7 power supplies, have post pass transistor regulation and may be considered golden reference variants. The filename conventions follows the guide above with dual, single, S and SWS versions available. circlotronhvpowerdualnew.zip appears to be derived from the version 1.7 topology with a similar complement of transistors. On the underside of the pcb there are two additional stn0214 transistors compared to the version 1.7 plus 3 mount points for a total of 500V worth of smd zeners. circlotronhvpowerdualnewer2.zip ditches the zener string and introduces another stn3960 and includes sw and sws variations. The kgsshv8g.pdf power supply appears to be an predecessor version of version 1.5. There are very close similarities in topology including no post pass transistor regulation. Current sense is still controlled by a 2n3904. The pre-regulator is 10m90s controlled by a zener string and a quad of transistors like the version 1.5. However the pass transistor is two parallel fqpf8n80c. The control transistors are 2sa1486 instead of stn9360 and 2sc3840 instead of stn0214. Both types of control transistor are no longer in production and hence the conclusion this is older than version 1.5. Apparently these boards are classified as KGSSHV ------------------------------------------------ Version 1.5 boards ------------------------------------------------- predecessor to the golden reference with no post pass transistor regulation the board uses a single high wattage bleed resistor for each cap uses multiple stn9360s, stn0214s uses a serial zener string for to control the 10m90s pre regulator.
