Tea is having more boards made specfically for us at beginning of the year. The store should have their boards around Christmas. One column should say CL60 instead of both being CL30. Please confirm you selections, as i need some concrete numbers.

"theguy" was nice enough to come up with a helpful spreadsheet to get all info together. I will add any info that is not clear or needs better definition. Please check it for accuracy and let me know if there are any errors.

Thanks, "theguy". you will be rewarded for your efforts.

Hi, Buzzforb

For the V3 PSU, how many CL30 and CL60 are required for each channel?
Also, since I am a newbie, I am worry that I might blow up some of the FET's while assembling and/or testing the amp, is it possible to get an extra set, if I decide so?

Thanks again for the effort!

Regards,

[buzzforb]

You treat a V3 almost like it was a stereo V2. CL30 adnd 60 are included in the PSU components, but you can get extra if you want them. You can get as many fets as you want to pay for

Great news on the boards (I presume this refers to both main and PSU), have updated spreadsheet to reflect this. Interesting to see that Tea Bag is now doing an F6 board group buy.

Looking at the PSU schematic I'm seeing two thermistors, and the text refers to a CL30 and a CL60, so presuming the 2 quantity on the first line item in original post was a typo...have updated spreadsheet to reflect one CL60, one CL30, assuming that the CL60 was the more expensive one, hope this is correct.

Another thing I'm not clear on here is whether the V1 and V2 use the same PSU components (as the thread would seem to indicate). The manual states in the V2 section that "you are going to need a beefier power supply to do deliver all this additional power"; is your V1 PSU the same to simplify the group buy and potential upgrades, or am I misinterpreting the positioning of the manual text?

Main schematic and text also seems to show that V2 is V1 plus some diodes on the output, though not clear whether the mosfets are different since V2 schematic shows FQA19N20 and FQA12P20 where V1 schematic shows FQAN and FQAP (is this just an abbreviation?). If V2 is V1 plus diodes, then I'll take V2 for potential later upgrade.

Also updated RKH request to reflect no PSU or Mosfets/Diodes... hope I have this right, could have sworn I saw a post requesting the Mosfets/diodes, but not seeing it anymore.

Lastly, thanks to those who updated spreadsheet themselves.

Gentlemen,

In the PSU schematic, there is a thermostat set at 75oC in series with the power switch, is this necessary? If it is, then where should this thermostat be located (somewhere on the heatsink)?

V2 is V1 with diodes. Everything else is the same, simple as that. The thermostat in the psu is not something i have used, so i cant comment. If you want TeaBags PSU boards, it might be smart to go through me, as this will save shipping, including it with GBcomponents. Its up to you. I will create a spot on spreadsheet for this option. I will send out collection/communication emails tomorrow.

Edit
I have noticed folks adding thermistors. I assume that these are in addition to the ones included in the psu component kit. If not, please specify as extra
