It is just for reference from my carbon Bom list. You could check these part No. from www.mouser.com 1. 584-OP27GPZ 2. The normal 2.5mcd should be OK. (859-LTL-4221NLC) 3. 941-C2M1000170D

Payment sent. Because I can't not use the gift payment with paypal in our Country. So I sent you the total amount plus the extra fee 4%(not sure whether it is enough). Thanks a lot.

Changed to FT Caps with 32pcs instead of the mcap 12pcs. Thanks

Hello, I've ordered a transformer with the spec: Primary voltage 0-115-230V 50/60Hz Secondary voltage: 2x 360V @350mA 18-0-18V @1A Because I'm going to build the carbon with the 20mA outupt. Should I change the value of the resistor from 5.1ohm/3W to 3ohm/3W? Thanks.

Thanks a lot.

Hi everyone. I'm going to order the transformer for the kgsshv carbon. So the output of the transform will be 360V @200mA x2 and 15V-0-15V @500mA is it correct？ Thanks a lot.

I'm in for 16 Mundorf caps. Updated the spreadsheet. thanks

Oh, what a great project! So It will be 8 boards+ 3 transformers to build the circlotron?

Finally, I got the three boards to work. I'm going to build the chassis and the panel the next week. For the psu board.the out put is +506V, -506V, Bias +586V, +14.82V, -15.15V For the amp board. : L+,L- :24V, L+,GND:6V, R+,R-: 34V, R+,GND:9V. Some notes for this build: 1)At first I forgot to connect the GND cable between the amp board and the psu board. I met a strange issue that the LED(D13) was dark when turn on the power. And then when I turn off the power,It starts to light again. 2)If I don't setup the jumper for neither the local or the gobal feedback. I got the o+,o- with about 1500V. Oh, my god!I turn off the power immediately and setup the jumper and now I get about 20~30V.

Hi RistaR I see. Thanks a lot for your kindly comment.

Thanks for all of the comment. But I've already ordered some STTH1210D, so is it OK to add some TO-220A insulator rube to this diode like this? http://www.ebay.com/itm/TO-220-Transistor-Silicone-Rubber-Cap-Insulator-x-10-/400244726109 ps: I'm building the large version of the PSU board.

Thanks a lot. I've found another problem with the fast recovery diode. In the latest bom it shows as:　STTH512FB　but it used the type : 511-STTH1210D (mouser PN). I found another type as 511-STTH512FP (mouser PN) mentioned in the megatron thread. I'm not sure what is the difference between the two types. And which one should I choose?

I've found that there is a CL60 thermistor in Yun's BOM. But I'm not sure how to mount this part on the PCB or in the connection wires. Is it functioned as a fuse? if so it is, could I put it between the transformer and the power switch? Any advice will be appreciated.
