My mess ..

Thats a mess, alright

New layout, symmetry not as good now though.

OMG! I don't think I want one now...

So, we were trying for a long time to get white boards with green silk screen. Ended up going green and putting the extra cost into more boards.

 

[steenoe]

white boards

I would jump offboard right away

Allright, I am seriously nitpicking here but we're running out of serious issues
Re: C4/C5, the standard lead spacing for box caps is 22.5mm not 20mm

Here is an issue: I would like to have 37,5mm pinout for the outputcaps! Is that possible, Russ? If it is only me wanting that, no need to worry! My preffered part for outputcaps has that pin dist. Have a peek

Russ,

I have my concerns about splitting the supply cap (C2/3) this is one circuit, one channel, shouldn’t it have only one supply voltage at any given time? Or what’s the reason for doing so?

Never seen this done before

I suppose I did it because it worked so well for metalman(Terry) and Kari.

It should not hurt anything in anyway.

Regarding the two 1000uF's, take a look at KK's schematic. It should be ok.

They are connected differently, in that case they are in parallel which is not the case with Russ schematic.

Russ, could you point to Metalman schematic?

here is my schematic

Dooh, I cant follow you Tony, sorry but thats propably me gone blind again Both C2 and C3 has their negative pin connected to GND, as they should.

I dont think it split's anything as such, its filtering for the Pos and the Neg side of the circuit.

The US sources I have found for Rifa PHE caps are geared to large purchasers. Does anyone know of a US source (small quantity)?

 

[Russ White]

For Steenoe and Nisbeth

Your wish is granted.

Cheers!

Ed that was me posting that
For your mistake I will offer you to buy 4 of those things for you and send them to you!! You just have to pay the excact price and postage Those Rifa's arent even so costly here in EU!!
Just let me know if you want them

Steen.

 

[steenoe]

I love you, Russ But dont tell anyone

[Ed LaFontaine]

Sir Steenoe, You have mail.

 

[steenoe]

Sir Steenoe, You have mail.

I thought so
Ok I just checked the prices, so here is the pleasant news The 10uF's cost 5,5usd. You can have them in 15uF too at 7,2usd
Cant believe they sell that stuff at those prices But what, I dont complain Sorry but postage is added, too. Maybe if some of you US guys could get together, and organize a lokal distributor?? I will do the footwork here in EU.
