for all Cloney Users who have the PCB Version Z17/10 mk4 cba SME (from 2017/18) please use this link :  The Cloney - secret files

important is the issue on the Z card or you short -9 and 12V 

the latest Version is Z19/09 Mk4 cba (you find it on rear of the Z card) for this is  following issue list except my build tips which are for all versions

ID	MatthiasIssueNr.	Issue release date	Issue	Solution
1	29	19.dec.2019	When mounting the matrix to the lower frontpanel by the ground terminals, a distance of 1 - 1.5 mm can be noticed between the matrix's surface and the frontpanel. Caused by the production charge of the ground terminals. In this charge the isolating upper bushing of the terminal is longer than usual. See the attached graphic therefor.	File down the narrow part of the bushing to at least 3 mm or less. Use a file or some sandpaper, a countersink will also help. Another option is to re-drill the matrix at these two holes to the diameter of 8.6 mm. Plan B: try a washer or 2 of them (not tested yet) Plan C:  Re-drill the matrix at these two holes to the diameter of 8 mm and file down the tooth.
2	28	16.dec.2019	At the Z board there is a link missing on the 12 V trace. See the attached photo The failure affects OSC 1..
3	27	16.dec2019	At the Z board the captions of the presets are not printed.	See herefor the attached page of the population guide.
4	26	08.dec2019	"I meanwhile realized the EK construction manual gives no detailled information about mounting the matrix to the lower panel. So I decided to extend the manual by an additional page. Find this new page attached to this Newsletter. With this change, the actual EK construction manual now is rev. 1.24 and will be part of the next shipments (serial 078, 101, 106)."
5	25	04.dec.2019	PCB Version: Y19/09/mk4 cba There is no trace error at the X board. It is at the Y board - I am sorry. As reported, it was already soldered by Derek before packing the Electronics-Kit. But its good to check this one more time, as the soldered wire can be fallen off whilst transportation or handling.	Therefor see the attached photo. If this link is not present, solder a piece of wire to complete the trace.
6	24	03.dec.2019	There is a track error at the -9 V rail. Its at the bottom of the Z board area in the BACKPLANE !! See the attached backplane photo.	Solution: Solder a cable as shown in the picture (yellow link) to connect the right part of the -9 V rail. The upper panel is usually connected to the power rails by one of the 4-pin sockets in this area.
7	22	03.dec	Info only: Please refer to page 2 of the Population-Guide Version 1.92	population guide_1.92_page2.pdf
8	--	23.dec	Info: the 1K 2Watt resistor for the X board is for the PSU wiring... not on the X board pcb use 1% metal film resistors or select the 2% resistors on board X.
9	Issue 30	27.dec	R 12 (PSU / earth link) The wiring diagrams were not correct since an update earlier. This causes a parasitic voltage and in some cases obviously a strange behaviour	Solution: Exchange the specific pages at your manual by the updated pages attached to this newsletter and follow these instructions. So the next shipments will include construction manual rev. 1.26 or even a higher revision. File: 2019 PSU issue.pdf
10	--	29.dec	howto for X card remove the Pin 4 and 8 (the connector for the 2 TIp3055)
11			use a 7mm drill that the flat screws fits flat on bottom of the PSU base plate, only as seen on the picture on right side. wide also the fuse holders with a 4mm drill that the delivered screws from the kit will fit thru the fuse holders.
12	31		Major Problem: At 110 - 120 V mains voltage, the primary wiring of the 115 V transformer causes problems on the secondary coils/outputs	Solution: Change the primary transformer wiring to the way, shown in the diagram attached to this Newsletter.
13	Patrick Issue		Problem: the regulators are too hot for my experience - we waste too much energy in heat	the 18V AC transformer is "wrong" here - we have a 27V DC output after the bridge rectifier, beer we only need 15V DC. so I tried a 12V AC transformer which gives you a stable 18V DC output under load which is much better, the heatsinks are only at 22-30 degrees instead of 50C or higher. TME PART number:  TS20/023 please note: you have to drill 3 holes in the PSU back plate to mount this.
14	Patricks		Problem: Envelope bleeds in VCOs	the Lamp is the root cause. it can be replaced by a LED (preferred yellow) you also Need a 6V8 zener (6.8V zener Diode and cable tube/shrink) it was tested by me and works fine. TME Led holder with included LED: 2658.8073 (mentor vendor part nr.) 6v8 zener diode:   BZX55C6V8-TAP
