does the x07 drivers fit into x04 or previous? from my knowledge they do not.

Correct my posting, thanks. Isn't 500V rails on the onboard KGSShv pushing it a bit?

http://www.aavid.com/product-group/accessories/washers (you need to make sure that the washer goes into the alu pad so not metal is exposed. As for the Zeners, it doesn't matter as long as the total sum is the same: 500V (DC450V) or 550V (DC500V) [As per comment by Spritzer below] if you are really kean on getting those 680uF/450V I can supply you some, pm me - wouldn't do it my self though ... those are in series and thus can withstand the 500V no prob As for the 2200uF/50V ....no big deal ....you might hear some strange noise when powering off the amp and have the headphone connected ...nothing to worrie about ....should you consider changing to 3300uF go for 35V rather than 25V ... and please change the rectifiers for the STTH512F as pointed out by several good people in here A general advice; please read this thread ...yes, all of it ... you might find yourself much better equipped afterwards....and answers to all your questions as well :o)

Update: 680uF caps are comming 23/10 (according to FTCap). As soon as I have got those I'll post pics, and start shipping.

Update: 470uF caps are comming 13/11 (according to FTCap).

At least it shows that one might spend at least as much time figuring out whether the stuff has been assembled correctly as one would spend building the stuff from scratch ... BTW doesn't the LV rectifier look a bit odd? Would be interesting to see the bottom side of the boards as well ...

the two resistors pointed out as 250ohm is governing the current in the output stage, at 250ohm you'll have 4.5mA ....at 180ohm you'll have 6.5mA ....the transistor can go to 10-12mA but then you need bigger heatsinks.

Did you buy it off someone at Head-fi?

Insanity is right, those rectifiers looks like the ones from the original BOM (more space between on that PCB) Those should be STTH512FP from the pics it seems like the isolating washers are missing from the 10m90 on your amp

Closing the Group Buy. As of today I got the price confirmed of 147USD/each if buying at least 12. Last chance is monday 12/10-15 as I'll place the order the 13/10-15.

Yep, some stax jack boards has been added ... part of the negotiation Jay did with PCBNet. /S Final shipping etc will be calculated when we get hold of the caps as well.

Just a brief comment on the picture; the regular HV PSU boards are NOT part of the circlotron GB ....only HV900, driver + output boards are included in the Circlotron GB. /S

You could replace the HD as a hole before sending it for service

Circlotron boards arrived at Jays today. Will start shipping ASAP.

Why the crossing of the 50k's??

Thnx Kerry.

Estimated ship date from PCBNet rgrd the Circlotron boards 22 of september 2015

About a month ago Kerry was testing some late revision Kevin had done to the boards. I don't know the latest status on this, maybe Kerry can chim in?

680uF/550V + some 470uF/550V are set for week 43, the reaminder of 470uF/550V are set for week 46. We are working on having all caps delivered week 43 (19.october-23.october) Thanks NoPants for pointing out the week issue.

Most caps are set for week 43, the remainder for week 46. Jay is currently trying to get everything delivered at the same time.
